5 / 1000+ resultsresearch Peptidylarginine Deiminase Isoforms Are Differentially Expressed in the Anagen Hair Follicles and Other Human Skin Appendages
PAD enzymes play a key role in hair growth and structure.
research Pattern of expression of c-Myc, Max and Bin1 in human anagen hair follicles
c-Myc, Max, and Bin1 help hair follicle cells mature and die.
research Effects of platelet-rich plasma application on hair follicle count, telogen/anagen ratio, and miniaturized hair ratio in patients with androgenic alopecia: alone or in combination with other treatments
PRP improves hair growth in androgenic alopecia, especially when combined with minoxidil.
research Amaranthus Extract Promotes Healthy Follicles and Anagen Hair Density-A Randomized Placebo-Controlled, Double-Blinded Study.
Amaranthus extract cream safely boosts hair growth in men with hair loss.
research Hair follicle changes following intense pulsed light axillary hair reduction: histometrical, histological and immunohistochemical evaluation
Intense pulsed light treatment effectively reduces underarm hair by making hair follicles smaller and extending their resting phase.

5 / 699 resultscommunity PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
community "Hair Follicle Stem Cells are quiescent 99% of the time and permanently reside in the hair follicle"
Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
community PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells
PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.
community Can pp405 revive dead follicles for long time bald people? Are those even dead? After 10+ years bald
PP405 may revive dormant hair follicles but is unlikely to help with long-term baldness where follicles are replaced by scar tissue. It is seen as a potential adjunct to treatments like minoxidil and finasteride, but its effectiveness on deeply fibrotic or scarred areas is doubtful.
community The ending of alopecia? Corticosterone inhibits GAS6 to govern hair follicle stem-cell quiescence
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.
