PRC2 Preserves Intestinal Progenitors and Restricts Secretory Lineage Commitment

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.

PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

Verteporfin followed by retinoic acid improves wound regeneration in mini-pigs. Retinoic acid does not significantly enhance regeneration in rabbits.

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.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.
