    TLDR TrichoScan helps identify subtle hair thinning in women with androgenetic alopecia.
    The TrichoScan method was used to assess female pattern hair loss (FPHL) in 28 women with androgenetic alopecia (AGA). The study found that miniaturization might be a relative and not an absolute measurement in FPHL, and only a few patients with FPHL would present with high counts of very thin hair. The study suggests that FPHL is a subtle and gradual diminution of hair diameter and decreasing hair quality in the androgen-sensitive area rather than the loss of large amounts of terminal hair and growing vellus hair instead. The TrichoScan procedure is a valuable tool for an office setting, but measurements of hair diameter at different scalp regions must also be undertaken.

      A user has been using finasteride and minoxidil for hair loss but is experiencing increased shedding and is considering using topical melatonin with a product called Rizn. Another user is skeptical about the effectiveness of topical melatonin due to issues with the research and lack of replication of results, while a third user expresses interest in the outcome of using Rizn after not seeing results from topical finasteride and minoxidil.

      A user is experiencing hair loss despite using dutasteride and oral minoxidil, feeling hopeless and considering a hair system. They are advised to try ketoconazole, seek a second opinion from a dermatologist, and consider treatments like finasteride, RU58841, and hair transplants.
