      community Is microneedling still worth it if I’m on oral minoxidil?

      in Microneedling  21 upvotes 1 month ago
      Microneedling may still be beneficial for those on oral minoxidil due to its effects on tissue repair and blood flow, not just absorption. Some users report mixed results, and the effectiveness of combining microneedling with oral treatments remains debated.

      Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community How true is the statement: dead follicles don't grow back?

      in Research/Science  107 upvotes 7 months ago
      Hair follicles usually go dormant rather than die, and treatments like finasteride, minoxidil, and hormone therapy can sometimes reactivate them, though results vary. Complete regrowth is rare, especially in long-term bald areas, but some individuals see significant improvement with these treatments.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  82 upvotes 2 years ago
      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.
