Tsc2 Disruption in Mesenchymal Progenitors Regulates Hair Follicles and TGF Beta Signaling

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.

A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

A potential non-invasive topical treatment targeting the WNT Signaling Pathway for hair regeneration is being researched, with positive results on human hair follicle cells. Current effective treatments for hair loss include Minoxidil, finasteride, and hair transplantation.
