Androgenetic Alopecia: Analysis of Proliferation and Apoptosis

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

The conversation discusses a new model for understanding androgenetic alopecia (AGA), linking it to dietary and lifestyle factors similar to PCOS, and highlighting the role of DHT, vascular damage, and inflammation. Treatments mentioned include Minoxidil, finasteride, and RU58841.

The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

The post discusses a theory that hair regrowth after transplant is due to the angiogenesis process (new blood vessels forming), not because the transplanted hair is unaffected by DHT. The responses highlight the established belief in 'donor dominance' (the importance of the hair's origin in transplantation) and skepticism about the new theory.

Androgenetic alopecia is affected by scalp DHT levels, not sensitivity, with treatments like finasteride and dutasteride aiming to optimize these levels. Personalized DHT management is crucial for effective hair growth.
