HDAC6-Dependent Deacetylation of NGF Dictates Its Ubiquitination and Maintains Primordial Follicle Dormancy

Relaxation may promote hair growth by reducing corticosterone, which affects hair follicle stem cells. Corticosteroids are used for alopecia areata, but their long-term use for androgenic alopecia is uncertain.

Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

PP405 shows promise in regenerating hair by activating dormant follicles. Other treatments like VDPHL01 and Breezula are also advancing, providing new hope for hair loss solutions.

PP405 is anticipated as a future treatment for dormant hair follicles, but its effectiveness and safety are uncertain. Current treatments include oral minoxidil and microneedling, with some avoiding finasteride due to side effects.

Pelage Pharmaceuticals' PP405 aims to treat hair loss by reactivating dormant hair follicle stem cells, showing promising results in early trials. The company plans to present their findings at the American Academy of Dermatology Annual Meeting in 2026.
