The Angiosome Theory, Flap Delay, and Scalp Surgery

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.

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.

The conversation discusses skepticism about the effectiveness of scalp tension theory and scalp massagers for hair regrowth, contrasting it with treatments like finasteride and minoxidil, which have more user-reported results. Participants question the belief in scalp tension theory, suggesting it may be a marketing tactic, while others argue for a multifactorial approach to hair loss.

Hair loss may be linked to blood flow and inflammation, with treatments like Minoxidil, finasteride, and quercetin being discussed. The conversation also mentions the role of 5AR enzyme distribution in hair follicles.

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.

Hair loss may be linked to blood flow issues, but DHT is considered the main cause. Treatments used include finasteride, RU58841, minoxidil, vitamin D3, microneedling, and dutasteride, but hair loss persists.
