PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
User experienced hair loss from Norwood 3.5 to Norwood 5 with diffuse thinning after using a hair system for 2 years. Tried Redensyl, Capixyl, Bicapil, Biotin, multivitamins, Fin, and Min without significant improvement, seeking advice for hair recovery.
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.
Microneedling is unlikely to damage existing hair if done with a device using a smaller needle count, like a 9-needle cartridge, and a stamping motion. Hair follicles are deeper than the typical needle penetration depth.
