Rare genetic variants in five specific genes are linked to male-pattern hair loss but only account for a small part of the risk.

Hair-Thread Tourniquet Syndrome is a rare condition where hair or thread tightly wraps around a child's body part, requiring quick treatment to prevent damage.

The research found that people's hair proteins vary, especially by ethnicity and body part, which could help identify individuals in forensic science.

Hair follicles can regenerate if cut at certain points, with stem cells in the upper part.

Hair-loss trials have increased, but need more diverse participants and standardized measures.

Minoxidil might partially activate estrogen receptors, affecting hair growth.

Sunlight exposure damages hair follicles, but certain stem cell-derived particles can reduce this damage and help with hair regeneration.

Some mutant mice have hair with abnormal cross-linking, mainly in the cuticle, not affecting other hair parts.

Blond hair lightens more with visible light directly, while ultraviolet light lightens it after washing by damaging other hair parts.

Dietary essential fatty acids improved skin and hair conditions and partially corrected fat composition in diabetic mice.

Hair loss in middle-aged women is often linked to insulin resistance and a family history of hair loss, particularly from their fathers.

The article explains how to diagnose and manage certain types of scarring hair loss.

Smaller particles of the drug carrier penetrated skin better, with 300 nm size being best for targeting hair follicles.

ALA-PDT is effective and safe for chronic X-ray dermatitis, providing complete or partial remission.

The upper hair follicle is stable, while the lower part allows movement during hair growth.

Platelet-rich plasma is most effective for hair loss treatment and wound healing in skin surgery, but more research is needed for consistent results.

Platelet-rich plasma is most effective for hair loss treatment and shows promise for skin healing and rejuvenation, but more standardized research is needed.

Different S100 proteins have specific roles in various parts of the hair follicle.

Overactive Wnt signaling in mouse skin stem cells causes acne-like cysts and shrinking oil glands, which some treatments can partially fix.

Hormones beyond androgens may cause acne and hair loss.

A trial showed that a new treatment is safe and effective for male pattern baldness, with most participants growing new hair.

Disrupting the Tsc2 gene in certain cells leads to thicker skin, larger hair, and changes in hair growth signaling, which can be partly reversed with specific treatment.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.

Early diagnosis and treatment are crucial for preventing permanent hair loss in various scalp conditions, and while new treatments are promising, more research is needed to evaluate their effectiveness.

Saudi dermatologists know about low-dose oral minoxidil for hair loss but don't often prescribe it, partly due to its unavailability.

GLP-1 therapies, especially semaglutide and tirzepatide, may cause hair loss, particularly in women and with rapid weight loss.
