    TLDR Human hair follicle stem cells can safely and effectively help nerve regeneration.
    The study explored the potential of human hair follicle pluripotent stem (hfPS) cells as a promising alternative to embryonic stem (ES) and induced pluripotent stem (iPS) cells for regenerative medicine. Unlike ES and iPS cells, hfPS cells were found to be more accessible, autologous, and safer, with no ethical concerns or risk of teratoma formation. The researchers demonstrated that hfPS cells could differentiate into various cell types, including neurons and glial cells, and effectively promote nerve regeneration. In experiments, human hfPS cells transplanted into the severed sciatic nerve of mice differentiated into Schwann cells, aiding in nerve regeneration and functional recovery. This highlighted the potential of hfPS cells as a viable source for regenerative therapies.

      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.

      Hair follicle regenerative therapy is being developed, with clinical trials planned in Japan, potentially allowing for hair cloning and eliminating the need for treatments like finasteride. If successful, the treatment could be available in Japan by 2025, but widespread access and affordability may take longer.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  140 upvotes 2 years 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.
