    TLDR Quick, accurate minoxidil measurement in hair loss products using photometric flow titration.
    This paper describes a photometric flow titration method for quickly and accurately determining the concentration of minoxidil in commercial hair loss products. The method involves a redox reaction between KMnO and minoxidil and was found to be faster and more efficient than chromatographic procedures. The study used Regaine and Neoxidil products, both of which contained 2% minoxidil, and recoveries from 97.6 to 102.8% were observed depending on the sample. The proposed method is a low-cost and easy alternative for determining minoxidil in commercial samples.

      in Minoxidil  3 upvotes 1 week ago
      A 17-year-old using 5% topical minoxidil experienced significant hair shedding after a year, possibly due to a "synchronization shed" and deficiencies in vitamin D and iron. Recommendations include continuing minoxidil, optimizing vitamin D and iron levels, and reducing tretinoin use if scalp irritation occurs.

      community Do you think oral minoxidil will become the standard for hair loss in 2026?

      in Minoxidil  142 upvotes 2 weeks ago
      Oral minoxidil is considered more convenient and effective for some users, with positive results reported, but concerns about side effects and availability persist. Finasteride remains a standard treatment, while some users explore combinations with other treatments like dutasteride and laser devices.
