    TLDR Hair follicle stem cells can become heart muscle cells.
    The study showed that hair-follicle-associated pluripotent (HAP) stem cells from mouse vibrissa hair follicles could differentiate into beating cardiac muscle cells, with the upper follicle part having the highest differentiation potential. These cardiac cells exhibited functional properties by responding to isoproterenol and propranolol. HAP stem cells also differentiated into neurons, glial cells, keratinocytes, and smooth muscle cells, indicating their versatility for regenerative medicine, particularly in heart disease and nerve repair. The study emphasized the accessibility and cryopreservation potential of HAP stem cells, suggesting their promise for therapeutic applications.

      community Please explain this Minoxidil phenomena

      in Minoxidil  56 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.
