community 10 month update - 4 in 1 topical solution + dermastamp (sorry for the low quality before)
A user shared their positive experience with a 4-in-1 topical solution containing finasteride, minoxidil, ketoconazole, and biotin, along with weekly microneedling using a 1.2mm dermastamp. The user reported no noticeable side effects and mentioned that the biotin likely doesn't contribute to hair growth.
