Human Hair Follicle and Epidermal Melanocytes Exhibit Striking Differences in Their Aging Profile Involving Catalase

Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

The conversation discusses potential causes of pigmentation around hair follicles, suggesting sebum buildup, autoimmune conditions, or dermatitis. Treatments mentioned include finasteride, dutasteride, and an anti-inflammatory diet, with a recommendation to consult a doctor for a proper diagnosis.

Stress can cause hair to turn grey due to stem cell depletion at the hair follicle base. Treatments discussed include Minoxidil, finasteride, and RU58841 for hair loss.

Catalase is discussed as a potential treatment for delaying or reversing grey hair, but no reliable medicine currently exists. Other mentioned treatments include Imatinib, senolytics like Quercetin and Fisetin, He Shou Wu, Argan oil, and reishi mushroom extract, though their effectiveness varies.

A user observed orange fluorescence on their nose and hair under a black light, indicating Cutibacterium acnes, which may contribute to hair loss alongside androgenic alopecia. A suggestion was made to use coal tar shampoo to address the issue.
