    TLDR Lead can help reveal and organize lipids in human hair.
    The study revealed that the organized fraction of lipids in human hair consisted of fatty acid bilayers, partly in the form of calcium soaps. Lead fixation on these lipids significantly enhanced the diffraction pattern, showing a strong orientation of these soaps parallel to the hair axis. This suggested that lead ion treatment could be a novel tool for revealing the presence and organization of lipids in hair, with potential applications in medical, environmental, and archaeological contexts.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  140 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.

      Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

      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 PP405 is NOT gray market jxl069

      in Technology  24 upvotes 1 week ago
      PP405 is a safer alternative to JXL069 for hair loss treatment because it penetrates the skin effectively and degrades in the blood, avoiding systemic toxicity. JXL069, when forced into the body, can cause dangerous side effects like lactic acidosis due to its inability to degrade safely.
