    TLDR Oxidative stress affects hair loss in men with androgenetic alopecia.
    This study investigated the effects of oxidative stress on dermal papilla cells (DPC) in men with androgenetic alopecia (AGA). The researchers found that balding DPC were more sensitive to oxidative stress than non-balding DPC, and that oxidative stress may play a role in the pathogenesis of AGA. The study also found that low oxygen conditions (2% O2) led to decreased DPC viability, proliferation, and increased senescence-associated beta-galactosidase activity. The study suggests that oxidative stress-associated senescence in DPC may contribute to the pathogenesis of AGA.

      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

      The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

      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  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.

      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.
