    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.

      community Minoxidil results - Starts July 7

      in Minoxidil  294 upvotes 3 days ago
      The conversation discusses the use of topical minoxidil for hair loss, with the original poster sharing positive results after three months of use without finasteride. Many users suggest adding finasteride to maintain gains, while others share their experiences and concerns about side effects and application methods.

      community Can oral minoxidil cause significant changes in blood pressure? (deprecated thread)

      in Minoxidil  214 upvotes 1 week ago
      The user is using oral minoxidil and dutasteride for hair loss and observed changes in blood pressure after taking oral minoxidil. They experienced no visible symptoms from topical minoxidil, finasteride, or other treatments and are seeking feedback on whether these blood pressure changes are typical for oral minoxidil users.

      community Hair has only gotten worse ~10 months on minoxidil.

      in Minoxidil  1 upvotes 2 weeks ago
      The user experienced worsening hair loss despite using finasteride and topical minoxidil, and is considering switching to dutasteride and oral minoxidil. They also tried microneedling and tretinoin with minoxidil, and are exploring Sulfogenz topical minoxidil.

      community Let's talk about the use of minoxidil 15%

      in Minoxidil  3 upvotes 2 weeks ago
      Minoxidil 5% is no longer effective for the user, who is considering stronger minoxidil or oral options despite availability issues. Suggestions include trying minoxidil 15%, oral minoxidil, microneedling, and exploring other treatments like finasteride and dutasteride.
