    TLDR A woman with lupus improved significantly from scalp hair loss after treatment, highlighting the need to identify psoriatic alopecia in lupus patients to avoid permanent hair loss.
    In 2017, a 26-year-old female with systemic lupus erythematosus (SLE) was diagnosed with psoriatic alopecia after presenting with scalp hair loss and scaly plaques. Dermoscopic evaluation showed "patchy dotted vessels," and histopathologic examination confirmed the diagnosis, revealing features such as psoriasiform epidermal hyperplasia and sebaceous gland atrophy. The patient had no family history of psoriasis and was being treated with chloroquine for SLE. After using topical desoximethasone, tar shampoo, and olive oil, she experienced significant improvement, with 75% hair regrowth within 3 months and no recurrence at 1 year. This case underscores the importance of recognizing psoriatic alopecia in SLE patients to prevent permanent hair loss, as it can occur without other psoriatic features.

      Diffuse hair loss and scalp biopsies

      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.

      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.

      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.

      A user experienced significant hair shedding and thinning 10 months post-hair transplant despite using minoxidil and topical finasteride. They are considering switching to oral finasteride or dutasteride and are also dealing with scalp conditions like seborrheic dermatitis.
