    TLDR Laser hair-comb therapy doesn't improve male-pattern hair loss.
    A study was conducted on two healthy men with male-pattern hair loss (MPHL) to investigate the efficacy of laser hair-comb therapy. The laser comb was used on one side of the head for 7.5 minutes for 3 days each week for 26 weeks. The assessors were blinded to the treated sites. The study found no change in any hair variable between the treated and untreated sides in either subject. There was, however, an unexpected seasonal change in both subjects, with an increase in the anagen percentage and the number of hairs > 30 mm in length per cm², and a corresponding decrease in the number of hairs < 40 mm in length per cm² occurring in both sites. The study concluded that despite widespread acclaim on the internet and in the lay press for laser-generated hair growth in MPHL, many questions remain and further investigation is needed before laser hair-growth therapy can be taken seriously or advocated for MPHL.

      In this conversation, 4990 discussed various treatments for hair loss, including oral minoxidil, PRP, transplan, Jak inhibitors, Dutasteride, Finasteride, Olumiant, Ketoconazole, RU58841, microneedling, baricitinib, and CCCA. They recommended scalp biopsies in unclear cases of DUPA, twice weekly to twice daily shampooing for topical minoxidil users, and two sessions spaced one month apart with follow up at month three to determine the effectiveness of PRP treatment.

      The conversation is about the effectiveness of finasteride (fin) in preventing hair loss after a hair transplant. Some users have experienced hair thinning and loss after stopping finasteride, while others have had success with finasteride and minoxidil (min) in maintaining their transplanted hair. The general consensus is that finasteride is important for younger patients to prevent further hair loss.

      Capronium Chloride and Trichoxidil are suggested as better alternatives to Minoxidil for hair growth without heart side effects. The Japanese Dermatological Association recommends topical Minoxidil over Capronium Chloride.

      A user shared their experience of hair loss progression after one year on dutasteride, expressing disappointment with no improvement and considering other treatments like RU58841. Other users offered mixed responses, some seeing no change, others suggesting the hair loss might have been worse without treatment, and discussing the role of testosterone and DHT in hair loss.

      A user named "LordGeek101" shared their positive experience with hair regrowth after using 5mg of finasteride daily, 5% minoxidil twice daily, and hormone replacement therapy (HRT) for 8 months. The user is transgender (MTF) and mentioned that the larger dose of finasteride was recommended by their doctor for better chances of hair revival.
