    TLDR Human hair follicles can be used to create heart muscle cells.
    The study demonstrated that human hair follicle-associated pluripotent (hHAP) stem cells, which are nestin-positive and keratin 15-negative, could differentiate into various cell types, including cardiac muscle cells, neurons, glial cells, keratinocytes, and smooth muscle cells. The upper part of human scalp hair follicles showed the highest potential for differentiation. When cultured in 10%FBS-DMEM supplemented with isoproterenol, the number of cardiac muscle cells derived from hHAP stem cells increased. This finding suggested that human hair follicles could be a viable source for producing HAP cells in sufficient quantities for heart, nerve, and spinal cord regeneration in clinical applications.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  138 upvotes 9 months 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.

      community Please explain this Minoxidil phenomena

      in Minoxidil  60 upvotes 1 year 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 Keratin microspheres - breakthrough

      in Research/Science  13 upvotes 8 months ago
      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
