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, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.
Prolactin and cortisol are identified as key factors in hair loss, with stress hormones impacting hair shedding. Finasteride and minoxidil are effective treatments, while DHT's role and individual sensitivity are significant factors.
Oral dutasteride is the most effective for hair regrowth, followed by oral finasteride and minoxidil. Topical finasteride combined with minoxidil is recommended for those avoiding systemic DHT reduction.
TGF-B affects hair growth, both causing stem cell division and death depending on amounts. Amplifica's treatment injects Scube3 to increase TGF-B for hair growth.
