    TLDR Oxidative stress may play a role in causing alopecia areata.
    The study investigated oxidative stress in 62 patients with alopecia areata (AA) compared to 62 healthy controls. It found that patients with AA had significantly reduced erythrocyte superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities, and increased but statistically insignificant plasma malondialdehyde (MDA) levels. No significant differences were observed in erythrocyte catalase (CAT) activities or in oxidative stress markers concerning AA severity, duration, recurrence, or pattern. These results suggested a potential role of oxidative stress in the pathogenesis of AA.

      community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

      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.

      HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  138 upvotes 11 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.
