Scarring alopecia, also called cicatricial alopecia, refers to a group of hair-loss disorders that can permanently damage hair follicles and replace them with scar-like tissue.
Unlike many non-scarring forms of hair loss, scarring alopecia can cause permanent loss in affected areas. Therefore, recognising active disease and obtaining an accurate diagnosis early can be especially important.
Warning signs may include scalp burning, pain, itching, redness, scaling, pustules, crusting, tenderness, eyebrow loss or smooth areas where normal follicular openings are no longer visible.
However, not everyone experiences obvious inflammation. Some forms progress gradually with relatively few symptoms.
This guide explains the main types of scarring alopecia, possible symptoms and causes, how the condition is diagnosed, treatment options and when dermatology assessment is particularly important.

Medical note: Scarring alopecia can permanently damage follicles. This article provides general educational information and cannot diagnose the cause of hair loss. Prompt dermatology assessment is particularly important when scarring alopecia is suspected.
Direct Answer: What Is Scarring Alopecia?
Scarring alopecia is a group of disorders in which inflammation or another destructive process damages hair follicles and can replace them with scar tissue.
Once a follicle has been completely destroyed, normal hair growth from that follicle is generally not expected to return.
Therefore, treatment usually focuses on controlling active disease, protecting follicles that remain and preventing further permanent hair loss.
Key Takeaways
- Scarring alopecia can cause permanent hair loss. Inflammation or another destructive process damages follicles and may replace them with scar-like tissue.
- Early diagnosis matters. Once a follicle has been completely destroyed, restoring normal growth from that follicle is generally not possible.
- Inflammation can produce warning signs. Redness, burning, itching, scaling, pustules, pain, crusting, drainage or tenderness may indicate active disease.
- Some cases have few symptoms. Painless or slowly progressive loss does not completely exclude scarring alopecia.
- A scalp biopsy may be needed. A dermatologist may use biopsy findings to confirm the diagnosis and identify the inflammatory pattern.
- Treatment focuses on stopping progression. The main goals are to control inflammation and preserve surviving follicles.
- Different forms require different approaches. Lichen planopilaris, CCCA, folliculitis decalvans and discoid lupus are distinct conditions.
- Trichologists and dermatologists have different roles. A trichologist can recognise warning signs and support monitoring, while a dermatologist can provide medical diagnosis, biopsy and prescription treatment.

Concerned About Painful, Inflamed or Patchy Hair Loss?
Scarring alopecia deserves early assessment because ongoing disease activity can permanently damage follicles.
A qualified trichologist can examine the pattern, document changes and recognise warning signs that need medical referral. Meanwhile, a dermatologist can diagnose inflammatory scalp disease, perform a biopsy when appropriate and prescribe medical treatment.

Quick Next Steps if You Suspect Scarring Alopecia
- Check the pattern: Look for patchy loss, frontal hairline recession, crown-centred loss, eyebrow thinning or smooth and shiny areas.
- Examine the scalp: Burning, pain, redness, scale, pustules, crusting, drainage or tenderness may indicate active inflammation.
- Do not delay assessment: Active scarring alopecia can permanently damage follicles.
- Track changes: Take clear photographs under consistent lighting while waiting for an appointment.
- Avoid additional irritation: Pause tight hairstyles, harsh chemical treatments, excessive heat, scalp acids, undiluted essential oils and home microneedling.
- Arrange medical assessment: A dermatologist may need to perform trichoscopy, take a scalp biopsy or prescribe anti-inflammatory treatment.
What Is Scarring Alopecia?
Scarring alopecia is not one disease. Instead, the term describes a group of conditions that permanently damage hair follicles through inflammation, injury, infection or another destructive process.
The defining feature is damage to follicular structures needed for future hair growth.
In primary scarring alopecia, inflammation often affects the upper follicle and the region containing important follicular stem cells.
If inflammation destroys these structures, the follicle may lose its ability to regenerate and produce a normal hair shaft.
Over time, fibrous or scar-like tissue can replace the damaged follicle. As a result, the small follicular openings where hairs normally emerge may disappear.
This process distinguishes scarring alopecia from non-scarring conditions such as telogen effluvium and androgenetic alopecia.
In non-scarring hair loss, follicles generally remain present even when hair production is reduced.
For more detail about chemical processing and cicatricial alopecia, read The Truth About Cicatricial Alopecia and Chemical Straightening.
Primary vs Secondary Scarring Alopecia
Scarring alopecia can broadly be divided into primary and secondary forms.
- Primary scarring alopecia: The inflammatory disease primarily targets and damages the hair follicle. Examples include lichen planopilaris, CCCA and folliculitis decalvans.
- Secondary scarring alopecia: Follicles are destroyed as a consequence of another disease or injury. Causes can include burns, radiation, severe infection, trauma, surgery, tumours or deeply destructive inflammatory skin disease.
This guide focuses mainly on primary scarring alopecia.
How Scarring Alopecia Damages Hair Follicles
Inflammation drives many primary forms of scarring alopecia.
Depending on the condition, the inflammatory infiltrate may predominantly contain lymphocytes, neutrophils or a mixture of inflammatory cells.
These cells collect around the follicle and surrounding tissue. Persistent inflammation can eventually damage important follicular structures and produce fibrosis.
During active disease, a person may notice redness, scaling, itching, burning, tenderness, pustules, bumps, drainage or increased hair loss.
Later, affected skin may become smooth, pale, shiny, tight or scar-like. Normal follicular openings may no longer be visible.
Lymphocytic Scarring Alopecia
In lymphocytic forms, lymphocytes are the predominant inflammatory cells seen around affected follicles.
Examples include:
- Lichen planopilaris.
- Frontal fibrosing alopecia.
- Central centrifugal cicatricial alopecia.
- Discoid lupus erythematosus.
- Some cases historically classified as pseudopelade.
Neutrophilic Scarring Alopecia
In neutrophilic forms, neutrophils predominate in the inflammatory pattern.
Pustules, crusting, drainage, scalp bumps and tenderness may therefore be prominent in some of these conditions.
Examples include folliculitis decalvans and dissecting cellulitis of the scalp.
Mixed Inflammatory Patterns
Some scarring alopecias can show mixed inflammatory patterns. In addition, histological features can vary according to the stage of disease.
For this reason, a dermatologist may combine clinical examination, trichoscopy, cultures and biopsy findings before establishing a diagnosis and treatment plan.
Common Types of Scarring Alopecia
Scarring alopecias differ in their clinical appearance, distribution, symptoms and microscopic inflammatory pattern.
Important forms include lichen planopilaris, frontal fibrosing alopecia, folliculitis decalvans, discoid lupus erythematosus, central centrifugal cicatricial alopecia and dissecting cellulitis.
1. Lichen Planopilaris
Lichen planopilaris is an inflammatory form of scarring alopecia that typically involves lymphocytic inflammation around follicles.
It can produce irregular areas of hair loss together with redness and scaling around remaining follicles.
Burning, itching, discomfort or tenderness may also occur.
As the condition progresses, affected areas can become smooth, pale, shiny and permanently hairless. Normal follicular openings may disappear.
2. Frontal Fibrosing Alopecia
Frontal fibrosing alopecia is considered part of the lichen planopilaris spectrum.
It typically produces a band-like recession across the frontal and temporal hairline.
Eyebrow loss is also common. Some people develop facial papules, body-hair loss or redness and scale around hairs at the active margin.
The condition occurs most often in postmenopausal women. However, younger women and men can also develop it.
3. Folliculitis Decalvans
Folliculitis decalvans is a predominantly neutrophilic form of scarring alopecia.
It may cause persistent inflammation, pustules, crusting, soreness and progressive scarred areas.
Staphylococcus aureus is frequently associated with the condition. However, folliculitis decalvans is more complex than a simple bacterial scalp infection.
A characteristic finding is hair tufting, where several hair shafts appear to emerge together from one follicular opening.
Without adequate control, ongoing inflammation may destroy additional follicles.
4. Discoid Lupus Erythematosus
Discoid lupus erythematosus can affect the scalp and cause inflammatory plaques with permanent scarring hair loss.
Earlier lesions may appear red, scaly or thickened and can show follicular plugging.
Over time, affected skin may become lighter or darker than the surrounding scalp. It can also become thin, smooth, scarred and permanently hairless.
Discoid lupus can remain limited to the skin. However, medical assessment may be appropriate when symptoms or findings raise concern about systemic disease.
5. Central Centrifugal Cicatricial Alopecia
Central centrifugal cicatricial alopecia (CCCA) commonly begins around the crown or vertex and gradually spreads outward.
CCCA disproportionately affects women of African ancestry, although it is not limited exclusively to this group.
Learn more in our detailed guide to central centrifugal cicatricial alopecia.
The cause is complex and not completely understood. Genetic susceptibility and inflammation appear important.
Hair-care practices that create repeated tension, heat or chemical injury may add stress in some individuals. However, they do not fully explain the disease.
6. Pseudopelade of Brocq
Pseudopelade of Brocq is a rare clinical diagnosis historically used to describe slowly progressive areas of permanent scalp hair loss.
It may appear as small, irregular, smooth and pale patches with relatively little visible inflammation.
Because other scarring alopecias can eventually develop a similar appearance, specialist evaluation and sometimes biopsy are important before using this diagnosis.
7. Dissecting Cellulitis of the Scalp
Dissecting cellulitis is a deeply inflammatory scalp disorder.
It can cause painful nodules, abscesses, drainage, sinus tracts beneath the skin and permanent scarring hair loss.
The condition commonly affects the vertex and occipital scalp.
Because inflammation can become severe, medical treatment should not be delayed.
Scarring Alopecia Symptoms and Warning Signs
Symptoms vary according to the exact condition, disease activity and stage.
Some people experience obvious inflammation and discomfort. Others develop progressive hair loss with few symptoms.
Therefore, painless hair loss does not completely exclude scarring alopecia.
Changes in Hair Density and Distribution
- Patchy loss: Hair may disappear in small patches or larger irregular areas.
- Crown-centred thinning: Hair loss beginning around the centre of the scalp may occur with CCCA.
- Frontal hairline recession: Progressive band-like recession may occur with frontal fibrosing alopecia.
- Eyebrow thinning: This commonly occurs with frontal fibrosing alopecia and can occur with other inflammatory disorders.
- Tufted hairs: Several shafts emerging together can occur with folliculitis decalvans.
- Expanding areas: Existing patches may enlarge while inflammatory disease remains active.
Inflammatory Scalp Symptoms
- Redness: Redness around individual follicles can indicate active inflammation.
- Scaling or crusting: Fine scale, thicker scale, crusts or follicular plugs may develop.
- Pustules or bumps: These may be prominent in neutrophilic disorders.
- Burning or pain: Burning, tenderness or soreness can accompany active disease.
- Itching: Itching may range from mild to severe.
- Drainage: Fluid or pus may occur in deeply inflammatory disorders.
Signs of Established Scarring
- Smooth or shiny scalp areas.
- Pale, white, darker or otherwise discoloured skin.
- Loss of visible follicular openings.
- A thin, tight or scar-like scalp texture.
- Persistent areas without visible regrowth.
Scarring alopecia needs faster assessment than ordinary cosmetic thinning because ongoing inflammation can cause irreversible follicular loss.
What Causes Scarring Alopecia?
The underlying cause depends on the specific diagnosis.
For many primary scarring alopecias, researchers do not yet completely understand why inflammation begins to target the follicle.
Autoimmune and Inflammatory Activity
Several forms involve abnormal inflammatory or immune activity affecting structures around the hair follicle.
This mechanism is particularly relevant to conditions such as lichen planopilaris, frontal fibrosing alopecia and discoid lupus.
Genetic Susceptibility
Genetic susceptibility appears to contribute to some forms of scarring alopecia.
For example, familial clustering and genetic associations have been reported in CCCA.
However, genes alone do not explain every case.
Bacterial Involvement
Bacterial colonisation or dysbiosis may contribute to some neutrophilic disorders, including folliculitis decalvans.
However, antimicrobial treatment alone does not necessarily address the complete inflammatory disease process.
Hair-Care and Mechanical Stress
Repeated tension, excessive heat, chemical processing and scalp trauma can injure the hair and scalp.
These factors may contribute to or worsen problems in susceptible individuals, depending on the condition.
However, they do not explain every case of primary scarring alopecia.
For more detail, read Cicatricial Alopecia and Chemical Hair Straightening.
Infection, Injury and Other Diseases
Deep infections, burns, radiation, trauma, surgery, tumours and destructive inflammatory skin diseases can cause secondary scarring alopecia.
In these situations, treatment needs to address the underlying cause as well as the resulting scalp damage.
How Scarring Alopecia Is Diagnosed
Accurate diagnosis is important because different forms of scarring alopecia can require different treatment strategies.
Assessment may involve medical history, scalp examination, trichoscopy, biopsy, microbial testing and selected laboratory investigations.
1. Medical History
A clinician may ask when the hair loss began, how quickly it has progressed and whether affected areas continue to expand.
They may also ask about burning, pain, itching, scaling, pustules, drainage, eyebrow loss or body-hair changes.
Other relevant information may include autoimmune disease, medications, family history, previous infection, hair-care practices, chemical treatments, earlier diagnoses and previous therapies.
2. Clinical Scalp Examination
The scalp is examined for the pattern and distribution of hair loss.
The clinician may also look for redness, perifollicular scale, pustules, crusting, tenderness, smooth skin and missing follicular openings.
Location can provide useful diagnostic clues. For example, CCCA commonly begins around the crown, while frontal fibrosing alopecia affects the frontal or temporal hairline and often involves the eyebrows.
3. Trichoscopy
Trichoscopy uses magnification to examine scalp and follicular structures more closely.
Depending on the disease, findings may include:
- Redness or scale around follicles.
- Follicular plugging.
- Loss of follicular openings.
- White or fibrotic areas.
- Tufted hairs.
- Broken hairs or unusual shaft patterns.
- Characteristic vascular or pigment changes.
Trichoscopy can also help identify an active area for biopsy. However, it does not always replace histopathological examination.
4. Scalp Biopsy
A scalp biopsy can be particularly valuable when scarring alopecia is suspected or the diagnosis remains uncertain.
A dermatologist removes a small sample of scalp tissue under local anaesthetic.
The biopsy site is usually selected carefully. An active or recently affected margin often provides more diagnostic information than the centre of an old, fully scarred area.
A pathologist can then examine the tissue for inflammation, follicular destruction, fibrosis and the predominant inflammatory pattern.
These findings can help distinguish different cicatricial alopecias and separate scarring from non-scarring hair loss.
5. Bacterial or Fungal Testing
When pustules, crusting, drainage or infection-like symptoms are present, bacterial culture or fungal testing may be appropriate.
Results can help guide antimicrobial treatment when infection or microbial involvement is suspected.
6. Blood Tests
Blood tests do not diagnose most primary scarring alopecias on their own.
However, targeted tests may identify associated disease or an additional contributor to hair shedding.
Depending on the clinical history, testing may include:
- Autoimmune or lupus-related investigations.
- Inflammatory markers.
- Thyroid function.
- Iron and ferritin.
- Vitamin D or selected nutritional markers.
- Hormonal testing when medically appropriate.
Scarring Alopecia or Another Type of Hair Loss?
Patchy loss, crown thinning and hairline recession can have several causes.
However, burning, pain, pustules, persistent inflammation, smooth scar-like areas or loss of normal follicular openings increase concern about inflammatory or scarring disease.
| Arrange a Hair and Scalp Assessment |
How Scarring Alopecia Is Treated
The main goal of treatment is to control active inflammation before additional follicles are permanently destroyed.
Treatment may also reduce burning, pain, itching, scaling, pustules, drainage or crusting.
Once mature scar tissue has replaced a follicle, current medical treatment cannot reliably recreate that follicle.
Therefore, protecting the follicles that remain is usually the primary objective.
The treatment plan depends on the exact diagnosis, disease activity, severity, affected area, medical history, pregnancy considerations and response to previous treatment.
1. Topical Corticosteroids
Dermatologists may prescribe potent topical corticosteroids for selected inflammatory forms of scarring alopecia.
These medicines can reduce inflammation and related symptoms.
However, inappropriate or prolonged use can cause adverse effects such as skin thinning, visible blood vessels, folliculitis or pigment changes.
Therefore, treatment should be supervised by a qualified medical professional.
2. Intralesional Corticosteroid Injections
A dermatologist may inject a corticosteroid such as triamcinolone into selected active areas.
Intralesional treatment is used in some patients with conditions such as lichen planopilaris, frontal fibrosing alopecia or CCCA.
Possible adverse effects include temporary skin thinning, indentations, pigment changes and discomfort.
3. Oral Corticosteroids
Systemic corticosteroids may sometimes be considered for rapidly progressive or severe inflammatory disease.
Because these medicines can cause significant adverse effects, their dose and duration require careful medical supervision.
4. Oral Anti-Inflammatory or Immune-Modifying Medicines
Depending on the diagnosis and individual circumstances, a dermatologist may consider medicines such as:
- Hydroxychloroquine.
- Doxycycline or another tetracycline.
- Methotrexate.
- Mycophenolate mofetil.
- Cyclosporine.
- Pioglitazone in selected circumstances.
- Other diagnosis-specific immune-modifying therapies.
These medicines require professional supervision.
Some treatments also require blood tests, eye examinations, infection screening, pregnancy precautions or other safety monitoring.
5. Antibiotics and Antimicrobial Treatment
For folliculitis decalvans and selected other neutrophilic disorders, dermatologists may use antibiotics for their antimicrobial and anti-inflammatory effects.
The treatment choice depends on the diagnosis, culture results, disease severity, previous response and individual medical history.
People should not use leftover antibiotics or begin prolonged antibiotic treatment without medical supervision.
6. Anti-Androgen Treatment
Finasteride or dutasteride may be considered in selected patients, particularly in the management of frontal fibrosing alopecia.
These prescription medicines are not appropriate for everyone.
The prescribing clinician needs to consider contraindications, pregnancy risks, adverse effects, medication interactions and the individual’s medical history.
7. Diagnosis-Specific Treatment
Additional treatment depends on the underlying disease.
- Discoid lupus: Photoprotection and lupus-directed medical treatment may be important.
- Dissecting cellulitis: Treatment can include systemic medicines and, in selected severe cases, procedural or surgical approaches.
- Folliculitis decalvans: Antimicrobial and anti-inflammatory strategies may be combined.
- CCCA: Medical anti-inflammatory treatment may be combined with low-tension styling and gentle scalp care.
Do Hair-Growth Products Treat Scarring Alopecia?
No over-the-counter hair-growth product can replace medical treatment for active scarring alopecia.
Supplements, cosmetic serums and scalp oils do not stop the underlying inflammatory disease and cannot recreate follicles that have already been destroyed.
In selected patients, a dermatologist may use additional hair-growth treatment to support follicles that remain intact. For example, minoxidil may sometimes be used when non-scarred follicles are miniaturised or another type of hair loss is also present.
However, supportive hair-growth treatment should not delay diagnosis or treatment of active inflammation.
Why We Do Not Recommend a General Hair-Loss Product Here
Scarring alopecia is different from ordinary shedding or pattern hair loss.
The immediate priority is identifying and controlling the inflammatory disease before additional follicles are permanently damaged.
For that reason, Trichology.com does not present a supplement or cosmetic serum as a general treatment for scarring alopecia on this page.
Regenerative and Emerging Treatments
Researchers continue to investigate regenerative approaches for hair loss.
However, established scar tissue remains particularly difficult to treat because the original follicles may no longer be intact.
Platelet-Rich Plasma
Platelet-rich plasma (PRP) has been studied more extensively for non-scarring forms of hair loss.
Research into its use in cicatricial alopecia remains limited.
In selected patients with controlled disease, a specialist may consider PRP as an adjunctive treatment. However, it cannot reliably recreate follicles that have already been destroyed by scarring.
Therefore, diagnosis and control of active inflammation remain the priority.
Exosomes
Exosome-based hair-loss treatments remain investigational.
Products and treatment protocols vary, and questions remain about standardisation, regulation, safety and clinical effectiveness.
They should not be presented as a proven replacement for established medical treatment of active scarring alopecia.
Peptide-Based Treatments
Peptides are being investigated for several biological roles, including cell signalling and inflammation.
However, evidence supporting peptide products as standalone treatments for scarring alopecia remains limited.
Be cautious with claims that a topical or injectable product can reverse mature scar tissue or recreate destroyed follicles.
Can Hair Transplantation Treat Scarring Alopecia?
Hair transplantation is generally inappropriate while scarring alopecia remains active.
Ongoing inflammation may damage transplanted follicles and reduce graft survival.
In carefully selected patients, transplantation may be considered after the disease has remained clinically inactive for a prolonged period.
The required period of stability varies according to the diagnosis and specialist judgement.
Before surgery, the specialist may review symptoms, serial photographs, trichoscopy findings, biopsy results, treatment history and changes in the affected area.
Even when disease appears stable, transplantation in scarred scalp is generally less predictable than transplantation for ordinary androgenetic alopecia.
In addition, inflammatory disease can reactivate.
Scalp Care and Supportive Measures
Supportive scalp care cannot replace medical treatment.
However, reducing unnecessary irritation can help protect fragile hair and improve comfort.
Use Gentle Hair-Care Practices
- Avoid tight braids, ponytails, extensions and other high-tension styles.
- Reduce excessive heat from flat irons, hot combs and blow dryers.
- Avoid scratching, picking or aggressively brushing an inflamed scalp.
- Pause chemical treatments if they aggravate symptoms.
- Choose gentle cleansing and conditioning products.
- Avoid home scalp microneedling while inflammatory disease is active or suspected.
Follow the Prescribed Scalp Routine
A clinician may recommend a medicated shampoo, topical medicine or another scalp treatment.
Use treatment according to the prescribed instructions rather than independently increasing the amount or frequency.
More frequent application does not necessarily produce faster improvement and can sometimes increase irritation or adverse effects.
Correct Confirmed Nutritional Deficiencies
Nutritional deficiencies are not generally the primary cause of primary scarring alopecia.
However, iron deficiency, vitamin D deficiency, inadequate protein intake or another nutritional problem can coexist and contribute to additional shedding or poor hair quality.
Confirmed deficiencies should be treated appropriately rather than assuming supplements will treat the cicatricial disease itself.
Support General Health
Stress does not explain every case of scarring alopecia.
However, living with a chronic inflammatory hair-loss condition can itself create significant emotional stress.
Regular sleep, physical activity where appropriate, psychological support and management of other health conditions can support general wellbeing during treatment.
Avoid Trial-and-Error Hair-Growth Treatments
When inflammation is damaging follicles, early diagnosis and appropriate medical treatment matter more than experimenting with cosmetic hair-growth products.
Strong oils, scalp acids, undiluted essential oils, harsh exfoliants, home microneedling or poorly regulated treatments may aggravate an already inflamed scalp.

Can Scarring Alopecia Be Reversed?
Scarring alopecia can permanently destroy follicles.
Once mature fibrotic tissue has replaced a follicle, there is currently no reliable treatment that restores normal hair production from that destroyed follicle.
However, early treatment may stop or slow active disease before additional follicles are lost.
Inflammation around follicles that remain structurally intact may also improve with appropriate treatment.
The main goals are to:
- Stop or slow disease activity.
- Reduce burning, pain, itching, scaling, pustules or drainage.
- Preserve follicles that remain intact.
- Prevent additional scarred areas from developing.
- Consider cosmetic restoration only after disease stability has been established.
People who notice frontal recession, eyebrow thinning or a smooth band along the frontal hairline should also read about frontal fibrosing alopecia.
However, reading about the condition should not delay professional assessment.
How Treatment Progress Is Monitored
Symptoms can improve before visible changes become obvious.
Therefore, monitoring usually involves more than photographs alone.
A clinician may track:
- Changes in burning, pain, itching or tenderness.
- Redness, scale, pustules or crusting.
- Whether affected areas are expanding.
- Trichoscopy findings.
- Hair-pull findings around active margins when appropriate.
- Standardised photographs.
- Medication adverse effects.
- Required laboratory or other safety-monitoring results.
Do not stop prescribed treatment simply because symptoms improve.
Disease activity can sometimes persist despite reduced discomfort. Treatment changes should therefore be discussed with the prescribing clinician.
When to See a Trichologist or Dermatologist
Seek prompt professional evaluation if you notice:
- Persistent scalp burning, pain, itching or tenderness.
- Patchy hair loss with redness or scaling.
- Pustules, crusting, drainage or recurring inflammatory bumps.
- Smooth, shiny, pale or scar-like scalp areas.
- Loss of visible follicular openings.
- Rapidly progressive hair loss.
- Eyebrow thinning together with frontal hairline recession.
- Crown-centred thinning associated with pain, itching or tenderness.
- Hair loss that continues to progress despite ordinary treatment.
When to See a Trichologist
A trichologist can examine the visible pattern, document progression, review hair-care practices and identify warning signs that require medical referral.
A responsible trichologist should refer promptly when findings suggest inflammatory, autoimmune, infectious or scarring disease.
Learn more about what a trichologist does and when to see one.
When to See a Dermatologist
A dermatologist is particularly important when scarring alopecia is suspected.
Dermatologists can establish a medical diagnosis, perform a scalp biopsy, order appropriate investigations, prescribe medicines and monitor treatment risks.
Rapid progression, severe pain, drainage, pustules, smooth scar-like areas or loss of normal follicular openings should not be managed with cosmetic products alone.

Frequently Asked Questions About Scarring Alopecia
What causes scarring alopecia?
Scarring alopecia occurs when inflammation or another destructive process permanently damages hair follicles. The underlying cause varies according to the specific condition and can involve immune activity, genetics, infection, trauma or another scalp disease.
What does scarring alopecia look like?
Possible signs include irregular patches, crown-centred loss, frontal recession, smooth or shiny scalp areas, redness, scaling, pustules, crusting, skin-colour changes and loss of visible follicular openings.
Does scarring alopecia hurt or itch?
It can cause burning, itching, pain, tenderness or soreness. However, some people have relatively few symptoms, so painless hair loss does not completely rule out scarring alopecia.
How is scarring alopecia diagnosed?
Diagnosis may involve medical history, scalp examination and trichoscopy. Depending on the presentation, a dermatologist may also use scalp biopsy, microbial testing or selected blood tests.
Is a scalp biopsy always necessary?
No. However, biopsy can be particularly valuable when the diagnosis is uncertain, scarring disease is suspected or treatment depends on identifying the inflammatory pattern.
Is scarring alopecia contagious?
Primary scarring alopecia itself is not contagious. However, some infections can cause secondary hair and scalp disease, which is one reason an accurate diagnosis matters.
Can hair grow back after scarring alopecia?
Hair generally cannot regrow from follicles that have been completely destroyed and replaced by scar tissue. Early treatment may still preserve follicles that remain intact.
What treatments are available for scarring alopecia?
Treatment depends on the exact diagnosis. Dermatologists may use topical or injected corticosteroids, systemic anti-inflammatory or immune-modifying medicines, antimicrobial treatments and other diagnosis-specific therapies.
How quickly should treatment begin?
Assessment should be arranged promptly when warning signs of scarring alopecia appear. Earlier control of active inflammation may reduce additional permanent follicular damage.
Can minoxidil treat scarring alopecia?
Minoxidil does not control the underlying inflammatory disease and cannot restore destroyed follicles. However, a dermatologist may use it as supportive treatment for surviving follicles in selected patients.
Can PRP reverse scarring alopecia?
PRP cannot reliably recreate follicles that have already been destroyed. Evidence for PRP in primary cicatricial alopecia remains limited, although specialists may consider it as an adjunct in selected stable cases.
Can a hair transplant fix scarring alopecia?
Hair transplantation may be considered in carefully selected patients after a prolonged period of disease inactivity. Results are less predictable than for non-scarring pattern hair loss, and inflammatory disease may reactivate.
Is scarring alopecia the same as alopecia areata?
No. Alopecia areata is generally a non-scarring autoimmune alopecia in which follicles remain present. Scarring alopecia can permanently destroy follicles.
Can scarring alopecia spread?
Yes. Active disease can expand while inflammation continues. One of the main goals of treatment is to stop or slow further progression.
Is CCCA caused by chemical relaxers?
No single hair-care practice fully explains CCCA. Genetic susceptibility and inflammation appear important. Certain hair-care practices may contribute additional scalp or hair stress in some individuals.
Can scarring alopecia become inactive?
Yes. Treatment may bring inflammatory disease into a stable or inactive phase. Continued monitoring is still important because disease activity can sometimes return.
Should I see a trichologist or dermatologist?
A trichologist can recognise warning signs, document the pattern and support scalp and hair-care management. A dermatologist is needed for medical diagnosis, biopsy when appropriate, prescription treatment and management of inflammatory or autoimmune disease.
When is faster medical assessment needed?
Seek prompt assessment for rapid progression, significant pain, drainage, pustules, smooth scar-like areas, loss of follicular openings or eyebrow loss together with frontal recession.
Can oils or supplements treat scarring alopecia?
No oil or supplement can replace medical treatment of active inflammatory scarring alopecia. Some topical products may also irritate an already inflamed scalp.

Conclusion: Why Early Scarring Alopecia Treatment Matters
Scarring alopecia is a group of disorders that can permanently destroy hair follicles.
Once mature scar tissue replaces a follicle, normal hair production from that follicle is generally not expected to return.
Therefore, warning signs such as burning, pain, redness, persistent scaling, pustules, drainage, eyebrow loss, crown-centred thinning, frontal recession or smooth and shiny scalp areas should not be ignored.
Diagnosis may involve clinical examination and trichoscopy. In selected cases, a dermatologist may also need to perform a scalp biopsy or additional testing.
Treatment depends on the exact diagnosis and level of disease activity.
The main goal is to control inflammation, prevent further permanent loss and preserve the follicles that remain.
