001 Human scalp hair follicles are protected from alopecia areata in vivo by regulatory γδT cells

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.

Scientists discovered a new T cell treatment that could regrow hair. Users are skeptical but hopeful, with some relying on finasteride and minoxidil in the meantime.

Chinese researchers have successfully created hair follicles in vitro, potentially offering unlimited hair for transplantation and a cure for hair loss. They plan to test these follicles in vivo on human scalps.

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.

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 user proposed genetically engineering scalp stem cells to stop androgen receptors from causing hair loss. Others discussed the feasibility, existing research, and potential issues with this approach, including targeting the correct cells and unintended effects.
