Genotype Score Associated with the Risk of Androgenetic Alopecia

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

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.

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.

A dermatologist checked for hereditary hair loss using blood tests and plans to perform a trichogram. The user had slightly low Vitamin D3 levels, and the trichogram may help confirm androgenetic alopecia.

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.

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.
