Growth Factors and Microneedling in Alopecia Areata: A Narrative Review

The conversation discusses using microneedling with growth factor serum, PRF injections, dutasteride, oral and topical minoxidil, and topical exosomes to treat hair loss, particularly on the crown. OP plans to microneedle twice a month and seeks feedback on Korean growth factor serums.

The conversation is about experimenting with microneedling and growth factor topicals for hair growth, avoiding Minoxidil due to shedding concerns. The treatment includes microneedling, growth factor topicals, finasteride, biotin, and a caffeine shampoo.

Microneedling may enhance hair loss treatment by increasing the effectiveness of topical minoxidil, especially for those lacking the necessary enzyme to activate it. It might also work by triggering growth factors and improving topical absorption.

A 22-year-old has been using minoxidil and finasteride for four years with limited success and recently added microneedling to their regimen. They have seen some hair regrowth and are advised to continue using minoxidil alongside microneedling and consider lifestyle factors like diet and stress.

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.

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.
