    TLDR Laser treatment may help with hair growth in some people with frontal fibrosing alopecia, but results vary and the exact way it works is unclear.
    In a study from 2017, five female subjects with frontal fibrosing alopecia (FFA) were treated with a 1064 nm Nd:YAG laser to assess its effects on hair loss and potential hair regrowth. The participants, with an average age of 53.6 years, underwent three laser treatments. The outcomes varied: two subjects reported symptom stabilization, two experienced reduced pain and itching, and two noticed prevention of hair loss with new hair growth in two cases. However, one participant felt the treatment worsened hair loss. The study proposed that the laser might promote hair growth by enhancing blood flow and stimulating certain growth factors and cytokines, possibly through the Wnt-ß-Catenin-Lef1 signaling pathway. Despite these findings, the precise mechanism of hair restoration via laser treatment in FFA remains uncertain, indicating a need for further research.

      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 user shared their 6-month hair regrowth progress using finasteride, minoxidil, biotin, and iron supplements, along with occasional microneedling and specific shampoos. They reported minimal side effects and no retrograde alopecia, attributing their success to a combination of treatments.

      community Where to Begin with Microneedling?

      User is considering microneedling to enhance hair regrowth after limited response to minoxidil and better results with finasteride and ketoconazole shampoo. Recommendations include using a 1.5mm derma roller once a week, avoiding minoxidil on microneedling days, and disinfecting the roller with isopropyl alcohol.
