    TLDR Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.
    In 2009, researchers successfully developed a method to expand human hair follicle dermal papilla (DP) cells in vitro, maintaining their hair-inductive potential for potential use in hair loss treatments. The expanded DP cells, after approximately 36 doublings, were able to consistently induce hair formation in an in vivo flap-graft model, and the induced hair follicles persisted and could regrow even 11 months post-grafting. Out of nine human DP cell cultures expanded for three passages, seven induced robust hair growth, one showed intermediate results, and one did not induce hair growth, with the inductive potential maintained through at least eight passages. The study confirmed that the cultured DP cells were responsible for hair induction as they formed the DP and connective tissue sheath of the follicles. This research marked a significant step towards developing new therapies for hair loss by demonstrating that cultured human DP cells can be used to induce hair growth.

      The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

      A user with aggressive male pattern baldness found that topical melatonin significantly reduced their hair shedding to 1 or 2 hairs per day and noticed some thickening of side hair. They tried many treatments like finasteride and minoxidil with little success, but topical melatonin showed immediate results in reducing hair loss.

      A user plans to experiment with creating new hair follicles using methods like derma rolling, applying lithium chloride, tannic acid, and various other substances including caffeine, ketoconazole, and raspberry ketones. They also consider using anti-inflammatories, immunosuppressants, and DHT inhibitors to potentially improve results.

      community I don't know how microneedling works so well but it does.

      Microneedling, combined with finasteride and minoxidil, appears to enhance hair growth, with users reporting noticeable improvements. The process involves using a 0.5mm derma roller, which some believe increases blood flow and stimulates hair follicles.
