Analysis of the Efficiency of Hair Removal by Different Optical Methods: Comparison of Trichoscan, Reflectance Confocal Microscopy, and Optical Coherence Tomography

    TLDR Trichoscan® is best for measuring hair growth, RCM for analyzing hair follicles, and OCT is useful for both.
    This study compared the efficiency of three noninvasive diagnostic tools—Trichoscan®, reflectance confocal microscopy (RCM), and optical coherence tomography (OCT)—in evaluating hair shaft and growth. Conducted on six female volunteers, the study measured hair growth on the lower leg over five days following hair removal. The results indicated that all three methods were reliable for measuring hair after removal. Trichoscan® was found to be the most suitable for measuring hair growth, RCM was best for analyzing hair follicles, and OCT served as an additional tool for evaluating both hair follicle and length.

      community Anyone here get results from topical melatonin?

      in Research/Science  11 upvotes 4 years ago
      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.

      community New Hair Loss Treatment: Adipose Derived Secretomes

      in Research/Science  17 upvotes 10 months ago
      Adipose-derived stem cell secretome showed significant improvement in hair density and growth, especially when combined with minoxidil, suggesting a synergistic effect. The study had limitations, including a small sample size and potential bias.
