    TLDR Light-based therapy can help regrow hair in different types of hair loss, but more research is needed.
    This review examines the use of low-level light therapy (LLLT) as a noninvasive treatment for various types of alopecia, highlighting its potential to stimulate hair follicle repair and promote regrowth. LLLT has shown efficacy in improving hair density and follicular responsiveness in androgenetic alopecia, especially when combined with minoxidil or finasteride. It also shows promise in prolonging the anagen phase and reducing shedding in telogen effluvium, though larger studies are needed. In alopecia areata, LLLT may aid regrowth by modulating immune responses and enhancing microcirculation. Emerging evidence supports its use in lichen planopilaris and central centrifugal alopecia, with reports of reduced inflammation and hair regrowth. Despite its promise, standardized protocols and long-term data are still needed.

      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.

      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.

      Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser light therapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.

      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.

      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.
