    TLDR Miniaturized hairs stay connected to muscle in alopecia areata, allowing possible regrowth, but not in androgenetic alopecia.
    The study found that miniaturized hairs in alopecia areata maintain contact with the arrector pili muscle (APM) while miniaturized hairs in androgenetic alopecia lose contact with the APM. The researchers suggest that the persisting contact between the APM and outer root sheath (ORS) predicts reversibility of miniaturization, which could explain complete hair regrowth in AA while hair loss is largely irreversible in MPHL and FPHL. The regression of the APM may be the result of a disease process that disrupts a stem cell population which maintains the APM as well as the follicle.

      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.

      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.
