    TLDR Hair follicle stem cells can help repair nerve injuries.
    The study demonstrated that nestin-positive, keratin 15-negative multipotent hair follicle stem cells, located above the hair follicle bulge, could regenerate impinged sciatic nerve injuries in ICR nude mice. These stem cells were transplanted around the damaged sciatic nerve, where they differentiated into glial fibrillary acidic protein-positive Schwann cells, aiding in the recovery of existing axons and functional restoration of the nerve. This research suggested that hair follicle pluripotent stem cells could serve as an accessible, autologous source for nerve regeneration therapies, particularly for nerves compressed by bony or hard surfaces.

      community Please explain this Minoxidil phenomena

      in Minoxidil  57 upvotes 2 years ago
      The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  141 upvotes 1 year ago
      The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.
