    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 limitations of existing drugs, such as scalp irritation and low absorption. It discussed recent advancements in formulation technologies that aimed to improve efficacy, including the use of rigid or deformable nanoparticles and techniques like iontophoresis, sonophoresis, microneedling, and solid effervescent granules. These innovations were intended to enhance drug delivery to the hair follicles, potentially offering more effective solutions for 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.

      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.
