The Hair Follicle Stem Cell Niche
The hair follicle stem cell niche controls the regeneration of each new hair growth cycle. This guide explains how follicular stem cells reactivate hair growth, why signaling can fail, and
The Hair-Iron Axis
The hair iron axis explains how ferritin, iron availability, hepcidin, and cellular energy influence hair growth. Low iron stores can disrupt anagen, trigger diffuse shedding, and impair regrowth even when
Hair Follicle Immune Privilege
Hair follicle immune privilege helps protect actively growing follicles from immune attack. When this protection fails, immune-driven inflammation can trigger alopecia areata and sudden patchy hair loss.
Microneedling and Dermarolling for Hair Growth
Microneedling may support hair growth, especially for androgenetic alopecia when combined with minoxidil. Learn the evidence, risks, needle depths, and safety tips.
GLP-1 and Hair Loss
GLP-1 medications may be linked to hair shedding through rapid weight loss, nutrient gaps, stress physiology, and telogen effluvium rather than direct follicle damage.
Botox and Hair Loss
Botox may support hair growth in selected cases by reducing scalp tension and improving circulation, but evidence is still early and it is not a standalone cure.
High Sugar Intake and Hair Loss
High sugar intake may worsen hair loss by disrupting insulin, hormones, inflammation, gut health, and nutrient delivery to the scalp.
PRP for Hair Loss
PRP for hair loss may improve hair density and thickness in selected cases. Learn how it works, what the evidence says, and who it may help.
Medications that Affect Hair Loss
Some medications can trigger hair shedding, thinning, or texture changes. Learn which drug classes are linked to hair loss and what to do safely.
Peptides and Hair Growth: Scientific Mechanisms, Clinical Evidence, and Practical Applications in Modern Trichology
Peptides may support scalp health, follicle anchoring, and healthier-looking hair, but they are not a cure for every type of hair loss. This guide explains the evidence, key peptides, formulation
The Hair–Gut Axis: Understanding How Gastrointestinal Health Shapes Hair Growth and Loss
Gut health may influence hair loss through nutrient absorption, inflammation, microbiome balance, immune regulation, and hormone metabolism. This guide explains the gut-hair axis and what it may mean for shedding,
Can Essential Oils Support Hair Growth?— Here is What Science Shows
Essential oils such as rosemary, thyme, lavender, sage, and ylang ylang may support scalp health and hair growth by improving circulation, reducing inflammation, balancing microbes, and supporting the scalp barrier.
