The conversation discusses using a low dose of topical finasteride to achieve hair benefits with minimal systemic exposure. Users share experiences and opinions on dosing, systemic buildup, and side effects of both topical and oral finasteride.
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 has been using topical finasteride and minoxidil for two years with decent regrowth and recently added microneedling to their routine. They are questioning if the small hairs observed are new regrowth from microneedling or just vellus or miniaturized hairs.
After 8 months of using topical finasteride, hair miniaturization continues, raising concerns about its effectiveness. Microneedling is suggested as a possible complementary treatment.
Topical finasteride as a potential alternative to oral finasteride for reducing DHT levels on the scalp with fewer side effects, and other hair loss treatments such as minoxidil.
