    TLDR New technologies may improve topical treatments for hair loss.
    The document reviewed the current evidence on topical treatments for scarring and non-scarring alopecia, highlighting the challenges and advancements in this field as of 2021. Alopecia, affecting both men and women, had limited approved treatments, with topical formulations often causing scalp irritation and having low drug absorption. Recent research suggested that new formulation technologies, such as the use of rigid or deformable nanoparticles and techniques like iontophoresis, sonophoresis, and microneedling, could improve drug delivery and efficacy. The study emphasized the potential of these innovative approaches to overcome existing limitations in alopecia treatment.

      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.

      The DHT itch is linked to hair loss and persists despite finasteride use; switching to dutasteride helped alleviate the itch and promoted regrowth. Some users suggest seborrheic dermatitis as a cause and recommend treatments like medicated shampoos, vitamin D, and minoxidil.

      Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.
