    TLDR Sam Shuster identified three types of hair loss in psoriasis and emphasized the need for better research to understand them.
    In a letter to the editor, Sam Shuster clarifies his findings on psoriatic alopecia, correcting a misquotation by Headington et al. Shuster had identified three types of hair loss associated with psoriasis: (1) hair loss confined to psoriasis lesions due to dystrophic anagen follicles, (2) an acute telogen effluvium not confined to lesions, mostly in severe psoriasis, and (3) a less common destructive alopecia with a paucity of follicles and perifollicular inflammation, which surprisingly showed potential for regrowth after 10 years, contrary to initial beliefs of permanency. Shuster criticizes Headington et al. for not clinically identifying or grading alopecia in their patients, which he believes limits progress in understanding psoriatic alopecia. He emphasizes the need for a more comprehensive study of the condition.

      community No idea what's causing my hair thinning

      in Chat  2 upvotes 3 months ago
      The user is experiencing diffuse hair thinning despite using finasteride and oral minoxidil, with no hairline recession or bald spots. Suggestions include checking for telogen effluvium, considering a JAK inhibitor for potential autoimmune issues, and conducting further tests to rule out other causes.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.

      community Androgenetic alopecia is a skin disease: DHT-mediated skin disorders

      in Research/Science  62 upvotes 1 year ago
      Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

      In this conversation, 4990 discussed various treatments for hair loss, including oral minoxidil, PRP, transplan, Jak inhibitors, Dutasteride, Finasteride, Olumiant, Ketoconazole, RU58841, microneedling, baricitinib, and CCCA. They recommended scalp biopsies in unclear cases of DUPA, twice weekly to twice daily shampooing for topical minoxidil users, and two sessions spaced one month apart with follow up at month three to determine the effectiveness of PRP treatment.

      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.
