Scientists found new and known long non-coding RNAs in mouse hair follicle stemcells that may be important for stemcell function and could be targets for cancer treatment.
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.
MCL-1 is important for hair follicle stemcell survival, but its impact on human hair regrowth is unclear. Minoxidil and finasteride are the main treatments, with doubts about new discoveries leading to effective human solutions soon.
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
Microneedling may enhance hair regrowth by transferring stemcells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
Hair loss is linked to DHT, with treatments like finasteride and minoxidil being common but not definitive. Economic interests influence research, and there is potential for new treatments like PP405 and RU58841.
