Does microneedling regrow hair on dormant bald regions which have been bald for many years?

The conversation covers aggressive hair regrowth treatments like Dutasteride, Minoxidil (oral and topical), RU58841, microneedling, and ketoconazole shampoo. It also mentions PRP, laser therapy, GHK-Cu injections, and hormone therapy for maximum regrowth.

Effective treatments for male pattern baldness include finasteride, dutasteride, and oral minoxidil. Non-effective approaches include oils, shampoos, serums, laser therapies, massages, vitamins, and microneedling.

Topical finasteride is considered a safer option for hair regrowth with fewer systemic side effects compared to oral finasteride. Some users report similar efficacy and side effects between topical and oral treatments, while others prefer topical due to reduced systemic exposure.

UCLA's PP405 shows promise in reactivating dormant hair follicles for hair loss treatment but is still in clinical trials. Minoxidil and finasteride remain common treatments until PP405 becomes available.

Tretinoin and microneedling both enhance hair growth through different mechanisms, with microneedling being considered safe for long-term use. Optimal microneedling needle length varies, but 0.8 mm is suggested for hair growth, and a Dermastamp is recommended to avoid skin damage.
