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.
Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.
A 24-year-old shared six months of progress using 1mg finasteride daily and topical minoxidil twice daily, reporting improved hairline and temples with no side effects. The user experienced initial shedding but noted significant regrowth and no erectile dysfunction issues.
