Genetic Studies on the Functional Relevance of Protein Prenyltransferases in Skin Keratinocytes

A 22-year-old male with high estrogen levels is considering finasteride for hair loss but is concerned about potential side effects due to his hormone levels and family history of diabetes. Users suggest consulting a doctor, possibly an endocrinologist, and considering lifestyle changes like diet and exercise to address visceral fat and insulin resistance before starting treatment.

UCLA's PP405 shows promise in reactivating dormant hair follicles for hair loss treatment but is still in clinical trials. Minoxidil and finasteride remain common treatments until PP405 becomes available.

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

The user is experiencing severe hair shedding despite using minoxidil, finasteride, ketoconazole shampoo, and dermarolling. They are considering changing treatments after stopping dermarolling and switching finasteride brands worsened the shedding.

PP405 shows promise in hair loss treatment, but stem cell therapy using adipose-derived stem cells and ATP also successfully reversed androgenetic alopecia in mice. Stem cell therapy is costly, and some doubt the effectiveness of PP405 based on press releases.

A 27-year-old male has been using topical minoxidil for over 8 months and added finasteride in January 2026, noticing new baby hairs. Users suggest these baby hairs will likely grow longer, indicating promising progress.
