An Investigation of Apoptosis in 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.

The conversation discusses androgenetic alopecia (AGA) and questions why treatments focus on lowering DHT levels instead of building resistance to it. It also touches on hair transplantation techniques using body hair.

A 20-year-old woman with androgenetic alopecia feels depressed about her hair loss, despite using topical minoxidil, spironolactone, and saw palmetto. Suggestions include trying oral minoxidil, higher doses of finasteride or dutasteride, and checking for vitamin deficiencies and heavy metal exposure.

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.

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.

Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.
