OP is trying various treatments (finasteride, minoxidil, nizoral, dermarolling, tretinoin) to regrow hair after 8 years of baldness. Users suggest persistence and possibly adding dutasteride, noting that age and consistency affect results.
PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.
Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.
The user is considering switching from finasteride to dutasteride due to continued hair loss and lack of improvement after 8 months. They plan to add minoxidil and are advised to give treatments more time, as progress can take years.
