    TLDR Stem cell treatments can potentially treat baldness, with one trial showing hair growth after injecting a hair-stimulating complex, and no safety issues were reported.
    In 2011, researchers, including Cheng-Ming Chuong and George Cotsarelis, were investigating stem cell treatments for baldness. Chuong's study highlighted the role of activator and inhibitor signaling in hair growth, while Cotsarelis found that balding men had similar stem cell populations to non-balding men, but early progenitor cells were reduced by over 80%. A trial involving 25 men with male pattern baldness showed that injecting a hair-stimulating complex resulted in the growth of 25 new hairs near the injection site, which continued to grow for at least two years. No safety issues were reported. Another company, Intercytex, was working on isolating dermal papilla cells to stimulate hair growth, but faced challenges in growing the cells.

      community A concise, easy-to-understand post on Androgenic Alopecia theory and its practical applications

      in Research/Science  92 upvotes 2 years ago
      The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      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.
