    TLDR FA2H is essential for normal fur and sebum production in mice.
    The study found that fatty acid 2-hydroxylase (FA2H) was crucial for normal fur development and sebum production in mice. FA2H was specifically expressed in sebaceous glands and necessary for synthesizing certain lipids. Mice lacking FA2H had enlarged sebaceous glands, altered sebum composition, and experienced hair loss during the telogen phase due to blocked hair canals. This highlighted the role of FA2H in maintaining hair follicle homeostasis and the importance of specific lipids produced by sebaceous glands.

      Regrowing hairline without the use of Minoxidil or Finasteride, and instead using mechanical stimulation such as Derma Roller, Nizoral, Zinc Pyrithione, Scalp Massage, Scalp Exercise, Fish Oil and other topical solutions. It is cautioned that there are risks associated with not using medically-prescribed treatments, but it is suggested to consider mechanical stimulation in addition to those prescribed treatments.

      community Fats on your Head to Stop Hair Loss?

      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.
