Lichen planopilaris (LPP) is an inflammatory form of scarring alopecia that can permanently destroy hair follicles.
Inflammation typically develops around the upper portion of affected follicles. As the disease progresses, follicles can be replaced by scar tissue, which means hair cannot regrow from follicles that have already been destroyed.
Common warning signs include patchy hair loss, scalp itching, burning, tenderness, redness around individual follicles, scaling and loss of visible follicular openings.
Because permanent follicular damage can occur, early recognition and appropriate medical assessment are important. Treatment focuses on controlling active inflammation, reducing symptoms and preserving follicles that remain intact.
This guide explains the symptoms, suspected causes, diagnosis, treatments, prognosis and warning signs of lichen planopilaris.

Quick Answer: What Is Lichen Planopilaris?
Lichen planopilaris is an inflammatory scarring alopecia in which immune-mediated inflammation damages hair follicles and can cause permanent hair loss.
The condition often causes irregular patches of hair loss together with redness, scaling, itching, burning or scalp tenderness.
Once a follicle has been replaced by scar tissue, regrowth from that follicle is unlikely. Therefore, treatment is aimed primarily at stopping active disease and preserving remaining follicles.
Key Takeaways
- Lichen planopilaris is a scarring alopecia. Active inflammation can permanently destroy hair follicles.
- Early symptoms matter. Itching, burning, tenderness, perifollicular redness and scaling may appear before extensive permanent loss develops.
- Hair loss is often irregular or patchy. Areas may gradually enlarge as disease activity continues.
- Loss of follicular openings is an important sign. Smooth areas without visible follicles can indicate scarring.
- Diagnosis often requires dermatologic assessment. Trichoscopy can support the diagnosis, while scalp biopsy may be needed when the diagnosis is uncertain or confirmation is required.
- Treatment aims to control inflammation. Corticosteroids and other anti-inflammatory or immunomodulating medicines may be considered according to disease severity and individual medical factors.
- Destroyed follicles generally do not regrow. Treatment success often means stabilization rather than restoration of hair already permanently lost.
- Hair transplantation is not appropriate during active disease. It may be considered only in carefully selected patients after prolonged disease stability.
Quick Next Steps
- Look for inflammation: Burning, itching, tenderness, redness or scaling around follicles should not be ignored.
- Check the scalp pattern: Irregular patches and loss of visible follicular openings can suggest scarring alopecia.
- Avoid self-treating indefinitely: Supplements, oils and cosmetic products cannot stop active inflammatory follicular destruction.
- Document progression: Take standardized scalp photographs every few months.
- Seek medical assessment early: A dermatologist can determine whether biopsy or prescription treatment is appropriate.
- Use trichology support appropriately: A trichologist can assess the visible hair and scalp pattern, monitor changes and help identify when medical referral is needed.
Experiencing Scalp Burning, Itching or Patchy Hair Loss?
These symptoms can occur with inflammatory and scarring alopecias, including lichen planopilaris.
A trichologist can assess the visible pattern and help identify signs that require medical referral. A dermatologist can provide medical diagnosis, perform biopsy when necessary and prescribe treatment.
What Is Lichen Planopilaris?
Lichen planopilaris (LPP) is a chronic inflammatory disorder affecting scalp hair follicles.
It belongs to the group of conditions known as primary cicatricial or scarring alopecias.
In active LPP, inflammation is concentrated around parts of the follicle that are important for long-term follicular survival. Continued inflammation can damage these structures and eventually replace the follicle with fibrous scar tissue.
The result is permanent hair loss within fully scarred areas.
LPP can affect adults of different ages and sexes, although it is commonly diagnosed in middle-aged women.
The condition is not contagious.
What Causes Lichen Planopilaris?
The exact cause of lichen planopilaris remains uncertain.
Current understanding supports an immune-mediated inflammatory process in which T lymphocytes attack components of susceptible hair follicles.
This inflammatory response can damage follicular epithelial cells and structures involved in follicular regeneration.
However, the reason this immune response begins in a particular person is not fully understood.
Immune-Mediated Inflammation
LPP is considered part of the lichenoid group of inflammatory disorders.
Immune cells accumulate around affected follicles and can damage the upper follicle, sebaceous gland and follicular stem-cell region.
This differs from alopecia areata, which is also immune mediated but usually does not permanently scar the follicle.
Genetic Susceptibility
Genetics may influence immune susceptibility in some individuals. However, LPP is not considered a simple inherited disorder, and most people with the condition do not have a clear family pattern.
Environmental or Medication Factors
Researchers have investigated whether medicines, infections, hormones, environmental exposures or other immune triggers contribute to disease onset.
However, evidence for any one specific trigger remains limited. Therefore, it is usually not possible to identify one definite external cause.
The Role of Inflammation
Active inflammation is central to disease progression.
When inflammation continues, the follicular structure can be progressively damaged. This is why controlling active inflammation is more important than attempting to stimulate growth in areas where follicles have already been destroyed.
Symptoms of Lichen Planopilaris
LPP can vary considerably between individuals.
Some people develop obvious inflammatory symptoms. Others notice progressive thinning or irregular bald areas before significant discomfort occurs.
Hair-Loss Pattern
- Irregular patches of hair loss: Areas may appear scattered rather than following the predictable pattern seen with androgenetic alopecia.
- Progressive enlargement: Existing areas may expand when inflammation remains active.
- Loss of follicular openings: Scarred scalp areas can look smooth because follicular openings disappear.
- Permanent loss in scarred areas: Hair cannot normally regrow from follicles that have been completely destroyed.
Scalp Symptoms
Active LPP may cause:
- Itching.
- Burning or stinging.
- Scalp tenderness.
- Pain.
- Redness around follicles.
- Perifollicular scaling.
- Fine scale surrounding individual hair shafts.
The intensity of symptoms does not always correspond perfectly with the amount of active disease. Therefore, an apparently quiet scalp does not always confirm complete remission.
What Does Active LPP Look Like?
Signs suggesting active inflammation may include:
- Perifollicular redness.
- Scaling around individual follicles.
- New areas of hair loss.
- Expanding borders around existing patches.
- Burning or scalp tenderness.
- Short broken or dystrophic hairs near active borders.
By contrast, long-standing scarred areas may appear smoother and paler, with fewer or no visible follicular openings.
Conditions Related to Lichen Planopilaris
Frontal Fibrosing Alopecia
Frontal fibrosing alopecia (FFA) is closely related to LPP and is often considered part of the same disease spectrum.
FFA typically causes progressive recession of the frontal and temporal hairline and may also affect the eyebrows.
Graham-Little-Piccardi-Lassueur Syndrome
This rare variant can involve scarring alopecia of the scalp together with follicular papules and non-scarring hair loss affecting other body areas.
Lichen Planus Elsewhere on the Body
Some people with LPP also have lichen planus affecting the skin, nails or mucous membranes.
However, many people with scalp LPP have no obvious lichen planus elsewhere.
How Is Lichen Planopilaris Diagnosed?
Diagnosis requires assessment of the scalp pattern, symptoms and signs of active inflammation.
Because several scarring alopecias can look similar, accurate diagnosis is particularly important before long-term treatment begins.
Clinical Examination
A clinician evaluates the pattern of hair loss and looks for redness, scaling, loss of follicular openings and evidence of active disease.
A trichologist can also document scalp findings and progression, but medical diagnosis and prescription management should involve an appropriately licensed clinician.
Trichoscopy
Trichoscopy uses magnification to examine scalp and follicular structures.
Findings that can support LPP include:
- Perifollicular erythema.
- Perifollicular scale.
- Loss of follicular openings.
- White fibrotic areas.
- Other changes associated with follicular scarring.
Trichoscopy can also help distinguish LPP from androgenetic alopecia, alopecia areata and other forms of hair loss.
Scalp Biopsy
A dermatologist may recommend a scalp biopsy when LPP or another scarring alopecia is suspected.
The biopsy is generally most informative when taken from an area showing active inflammation rather than from an old completely scarred patch.
Histopathology may demonstrate lichenoid inflammation around follicular structures, interface changes and perifollicular fibrosis.
Biopsy findings must still be interpreted together with the clinical examination because different scarring alopecias can sometimes share overlapping features.
Conditions That Can Resemble Lichen Planopilaris
Other causes of scarring or inflammatory hair loss may include:
- Discoid lupus erythematosus: An inflammatory autoimmune condition that can produce permanent scalp scarring.
- Folliculitis decalvans: A neutrophilic scarring alopecia often associated with pustules, crusting and tufted hairs.
- Central centrifugal cicatricial alopecia: A scarring alopecia that typically begins around the central scalp and crown. Read our guide to CCCA.
- Frontal fibrosing alopecia: A related condition primarily affecting the frontal hairline and temples.
- Traction alopecia: Long-standing mechanical tension can eventually produce permanent follicular damage.
How Is Lichen Planopilaris Treated?
The primary goal of treatment is to control active inflammation and prevent additional permanent follicular loss.
Treatment cannot reliably restore follicles that have already been replaced by scar tissue.
The appropriate plan depends on disease activity, symptoms, extent, rate of progression, medical history and response to previous treatment.
Topical Corticosteroids
Potent topical corticosteroids may be prescribed for localized active disease.
They can help reduce inflammation, itching and discomfort. However, strength, duration and application schedule should be determined by the treating clinician because prolonged corticosteroid use can cause adverse effects.
Intralesional Corticosteroids
Corticosteroid injections such as triamcinolone may be used in selected active areas.
The aim is to suppress localized inflammation and protect remaining follicles.
Injection concentration and frequency require clinician judgment because excessive treatment can cause skin thinning or other local adverse effects.
Systemic Treatments
More widespread, symptomatic or rapidly progressive disease may require systemic treatment.
Depending on the individual, dermatologists may consider medicines such as:
- Hydroxychloroquine.
- Doxycycline or another tetracycline when anti-inflammatory effects are desired.
- Short courses of systemic corticosteroids in selected severe cases.
- Methotrexate.
- Mycophenolate mofetil.
- Cyclosporine.
- Other immunomodulating therapies when clinically appropriate.
No single systemic treatment works for every person, and evidence quality varies between therapies.
These medicines require medical supervision because they have specific contraindications, laboratory-monitoring requirements and possible adverse effects.
What About Pioglitazone?
Pioglitazone has been studied as an off-label treatment for LPP because of proposed anti-inflammatory mechanisms.
However, evidence is limited and inconsistent. It is not a routine first-line treatment and has important systemic risks that require medical consideration.
JAK Inhibitors and Other Emerging Therapies
JAK inhibitors and other immune-targeting medicines are being investigated for difficult inflammatory hair disorders.
Small reports and early studies have explored their use in LPP. However, they should currently be considered specialist or emerging treatments rather than established routine therapy for all patients with LPP.
Platelet-Rich Plasma
Platelet-rich plasma (PRP) has also been explored in scarring alopecia.
However, evidence for LPP remains limited. PRP should not replace anti-inflammatory treatment when active scarring disease is present.
Can Minoxidil Help Lichen Planopilaris?
Minoxidil does not treat the immune-mediated inflammation responsible for LPP.
However, a dermatologist may sometimes use topical or oral minoxidil as an adjunct when non-scarred follicles remain or when androgenetic alopecia is also present.
It should not be presented as a treatment capable of reversing established scar tissue.
Can Supplements Treat Lichen Planopilaris?
No dietary supplement has been proven to stop active lichen planopilaris.
Correcting a genuine nutritional deficiency may support overall hair health, but iron, vitamin D, biotin, collagen, botanical DHT blockers or other supplements do not replace anti-inflammatory medical treatment.
This is why I would not add an Advanced Trichology product block to this page.
Hair Transplantation After Lichen Planopilaris
Hair transplantation is generally avoided while LPP remains active.
Ongoing inflammation may damage transplanted follicles and cause poor graft survival.
In selected patients with prolonged documented disease inactivity, a hair-transplant specialist and dermatologist may consider surgery.
However, there is no single inactivity period that guarantees success. Disease stability, biopsy findings when relevant, donor supply, scalp condition and risk of recurrence all need consideration.

Hair and Scalp Care With LPP
Hair-care changes do not cure LPP, but gentle routines may reduce unnecessary irritation.
- Avoid scratching inflamed areas.
- Use gentle cleansing appropriate for the scalp.
- Avoid very tight hairstyles.
- Reduce unnecessary traction from extensions or heavy added hair.
- Limit irritating chemical treatments when the scalp is inflamed.
- Use heat carefully.
- Report new scalp reactions to the treating clinician.
Do not assume that every flare is caused by a shampoo, food or cosmetic product unless there is evidence supporting that connection.
Does Diet Affect Lichen Planopilaris?
No specific diet has been established as a cure for LPP.
A balanced diet remains important for general health and normal hair production.
When laboratory testing identifies iron deficiency, vitamin D deficiency or another nutritional issue, correcting that problem may support overall hair health.
However, nutritional correction does not replace treatment for active inflammatory scarring alopecia.
Prognosis: Can Lichen Planopilaris Be Stopped?
LPP is unpredictable.
Some people experience periods of active progression followed by prolonged stability. Others have persistent or recurrent activity.
Appropriate treatment can help suppress inflammation and slow or stop further follicular destruction in many patients.
However, already scarred areas generally remain permanently depleted.
Therefore, treatment success is often measured by:
- No new areas of hair loss.
- No expansion of existing areas.
- Reduction in redness or scaling.
- Reduced itching, burning or tenderness.
- Preservation of remaining hair.
How to Track LPP Progression
- Take baseline photographs. Document the crown, part, sides and visible patches.
- Use consistent conditions. Keep lighting, hairstyle, camera distance and angles the same.
- Track symptoms. Record itching, burning, pain and tenderness.
- Record treatment changes. Note medication names, doses, injections and start dates.
- Monitor active borders. New redness, scale or expansion may indicate continuing activity.
- Attend follow-up appointments. Stable appearance does not always mean the inflammatory process has completely stopped.
When to See a Trichologist or Dermatologist
When to See a Trichologist
A trichologist can be helpful when:
- You are unsure whether hair loss is shedding, breakage, pattern thinning or scarring.
- You want standardized scalp photography and progress monitoring.
- You need help reviewing hair-care practices.
- You need identification of warning signs requiring medical referral.
When to See a Dermatologist
Prompt dermatology assessment is particularly important when you develop:
- Scalp burning or persistent pain.
- Redness surrounding follicles.
- Perifollicular scaling.
- Progressively enlarging bald areas.
- Smooth or shiny areas with loss of follicular openings.
- Eyebrow loss.
- Rapidly worsening hair loss.
- Uncertainty about whether scarring alopecia is present.
A dermatologist can provide medical diagnosis, perform scalp biopsy when indicated and prescribe treatments aimed at controlling active inflammation.

Frequently Asked Questions About Lichen Planopilaris
What is lichen planopilaris?
Lichen planopilaris is an inflammatory form of scarring alopecia. Immune-mediated inflammation damages susceptible hair follicles and can permanently replace them with scar tissue.
Is lichen planopilaris autoimmune?
LPP is generally regarded as an immune-mediated inflammatory disorder. T lymphocytes are involved in the inflammatory attack on follicular structures, although the exact cause of the abnormal immune response remains uncertain.
Is lichen planopilaris contagious?
No. LPP is not an infection that can spread from one person to another.
What are the first symptoms of lichen planopilaris?
Early signs may include scalp itching, burning, tenderness, perifollicular redness, scaling and new irregular areas of hair loss.
Can lichen planopilaris be cured?
There is currently no treatment that reliably cures LPP in every patient. Treatment aims to suppress active inflammation, reduce symptoms and prevent additional permanent follicular loss.
Can hair grow back after lichen planopilaris?
Hair generally cannot regrow from follicles that have already been completely destroyed and replaced by scar tissue. However, controlling inflammation can help preserve follicles that remain viable.
How is lichen planopilaris diagnosed?
Diagnosis is based on the clinical scalp pattern, symptoms and examination. Trichoscopy can support the diagnosis, and a dermatologist may perform a scalp biopsy when confirmation or differentiation from another scarring alopecia is needed.
Does lichen planopilaris always need a biopsy?
Not every case follows exactly the same diagnostic pathway. However, biopsy is commonly considered when a scarring alopecia is suspected, especially when the diagnosis is uncertain or treatment decisions depend on confirming the inflammatory pattern.
What is the best treatment for lichen planopilaris?
There is no single treatment that is best for everyone. Topical or intralesional corticosteroids may be used for localized disease, while systemic anti-inflammatory or immunomodulating treatments may be required for more extensive or progressive disease.
Does minoxidil treat lichen planopilaris?
Minoxidil does not control the underlying inflammatory process. It may occasionally be used as supportive treatment when viable follicles remain or another condition such as androgenetic alopecia is also present.
Can supplements stop LPP?
No supplement has been proven to stop the inflammatory follicular destruction caused by LPP. Nutritional deficiencies should be corrected when present, but supplements should not replace appropriate medical treatment.
Can stress cause lichen planopilaris?
Stress has been proposed as a possible contributor to inflammatory disease activity, but there is not enough evidence to say that stress directly causes LPP. The disease should not be attributed to stress without appropriate medical assessment.
Is frontal fibrosing alopecia the same as LPP?
Frontal fibrosing alopecia is closely related to LPP and is commonly considered part of the lichen planopilaris disease spectrum. However, its clinical pattern is distinctive because it predominantly affects the frontal and temporal hairline and often the eyebrows.
Can I have a hair transplant after LPP?
Hair transplantation may be considered in carefully selected patients after prolonged disease stability. It should not be performed during active inflammatory disease because transplanted follicles may also be damaged.
Conclusion: Managing Lichen Planopilaris Early
Lichen planopilaris is an inflammatory scarring alopecia that can cause permanent follicular destruction.
Because already scarred follicles generally cannot produce new hair, the main goal of treatment is to control inflammation before additional permanent loss occurs.
Symptoms such as scalp burning, itching, tenderness, perifollicular redness, scaling and progressive irregular hair loss should therefore be assessed promptly.
Diagnosis may involve clinical examination, trichoscopy and scalp biopsy. Treatment can include topical, injected or systemic anti-inflammatory therapies according to disease activity and individual medical circumstances.
Most importantly, LPP should not be managed as ordinary cosmetic thinning. Early recognition, appropriate medical treatment and structured monitoring provide the best opportunity to preserve remaining follicles.
