    TLDR Intralesional corticosteroids are the best for limited alopecia areata, oral steroids are less effective, and PRP is safe and promising, especially for children and severe cases.
    In a clinical study conducted on 45 patients with alopecia areata (AA), three treatment modalities were compared: oral mini pulse therapy with betamethasone, intralesional corticosteroids with triamcinolone acetonide, and platelet-rich plasma (PRP) therapy. The study was randomized and prospective, lasting 16 weeks. Results showed a reduction in the Severity of Alopecia Tool (SALT) score for all groups, with the scores decreasing from 13.27 to 7.52 in Group 1, 13.93 to 8.16 in Group 2, and 42.32 to 21.12 in Group 3. The mean grade of hair regrowth was 3.47 for Group 1, 3.80 for Group 2, and 2.93 for Group 3. The study concluded that intralesional corticosteroids remain the first choice of therapy for adults with limited AA, systemic corticosteroids are less effective than intralesional steroids, and PRP showed promising results, particularly in children and cases with extensive involvement, being safe and with fewer side effects.

      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.

      A user started taking 0.625mg oral minoxidil daily for hair loss, increased the dose to 1.25mg, and experienced a significant shed, losing 70% of scalp density. They cannot tolerate finasteride due to side effects but are hopeful for hair regrowth despite the shedding.

      A user's experience with hair loss treatments such as finasteride, ketoconazole, and oral minoxidil that have not yielded any results; other users suggest shaving the head or getting a wig, while others offer additional advice such as seeing a dermatologist, checking thyroid levels, switching to dutasteride and adding needling, and trying stemoxydine.
