    TLDR Microneedling can effectively treat hair loss and works well with other treatments, but more research is needed.
    The document reviews the potential of microneedle-mediated therapies for treating hair loss, highlighting their ability to enhance drug delivery and stimulate hair regrowth through mechanisms like wound healing and activation of signaling pathways. Microneedling is effective for various types of hair loss, including androgenetic alopecia and alopecia areata, and shows improved results when combined with treatments like minoxidil and platelet-rich plasma. The technology is minimally invasive and generally well-received by patients. The review emphasizes the need for further research to optimize treatment protocols and understand the biological mechanisms, with a call for more large-scale clinical trials to establish standardized guidelines. Additionally, microneedles are explored for their potential in hair transplantation and tissue-engineered hair regeneration, though challenges remain in optimizing materials and ensuring cell viability.

      A 35-year-old man, balding since 18, has seen growth of small, almost white hairs all over his scalp after 1.5 months on oral finasteride and minoxidil. Users suggest sticking with the treatment for a year, adding microneedling, and potentially trying RU58841 or dutasteride.

      The user improved their hair loss using finasteride, switched to dutasteride, micro-needling, Nizoral shampoo, and changed from topical to oral minoxidil, resulting in thicker hair, eyebrows, beard, and body hair. Commenters are impressed with the transformation, some mistaking the before and after photos for different people, and the user reports no side effects from the treatments.
