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.
Diet and lifestyle changes can reduce hair shedding but won't regrow hair lost to genetic male pattern baldness. Treatments like finasteride and dutasteride are necessary for significant hair regrowth.
Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
A 22-year-old is experiencing significant hair shedding and is using multiple treatments, including oral and topical minoxidil, finasteride, topical dutasteride, ketoconazole shampoo, and considering adding RU58841 and stemoxydine. Others advise patience, suggesting sticking to finasteride and minoxidil for at least a year before evaluating results, as initial shedding is normal and adding too many treatments can be counterproductive.
