Hairfollicle 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 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hairfollicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
A user who shared progress pictures of their scalp using a microscope camera, demonstrating the difference between healthy and miniaturized hair. Various explanations for the cause of this were discussed, such as DHT build-up in scalp sebum causing an autoimmune response leading to inflammation and eventual hair loss, with some suggesting a do-it-yourself treatment involving adding ascorbic acid powder to shampoo.
Vitamin E and K deficiencies due to exocrine pancreatic insufficiency may affect hair growth. A scalp biopsy is recommended to check for autoimmune-related hair loss.
High DHEA levels may contribute to hair loss by increasing DHT in hairfollicles, potentially explaining why finasteride is ineffective for some. Treatments like high-dose dutasteride and RU58841 are suggested, but the underlying cause, such as adrenal issues, should be investigated.
