    TLDR Researchers developed a simple and accurate method to measure Minoxidil in tablets using UV light.
    In 2019, researchers from the Department of Pharmaceutical Analysis at P. Rami Reddy Memorial College of Pharmacy in Andhra Pradesh, India, developed and validated a simple, precise, accurate, and economical UV spectrophotometric method for estimating Minoxidil in tablet dosage form. The method used 0.1N HCl as a solvent and found that Minoxidil shows maximum absorbance at 279.4nm. The drug showed linearity from the concentration range of 1-6µg/ml and a correlation coefficient of 0.9992. The method was statistically validated for precision, accuracy, ruggedness, robustness, the limit of detection, and quantitation as per the ICH guidelines. The researchers concluded that this method could be successfully applied for routine analysis of Minoxidil in bulk and tablet dosage form.

      Low Vitamin D can cause hair shedding, and taking 5000 IU of Vitamin D daily reduced shedding significantly. Vitamin D deficiency is common and correcting it can benefit overall health.

      community New Study - Flavonoids More Effective Than Finasteride?

      in Research/Science  148 upvotes 2 years ago
      A recent publication suggests that the flavonoids eriocitrin and silymarin may be more effective than finasteride in binding to the enzyme responsible for hair loss. People in the conversation are skeptical about the effectiveness and safety of these flavonoids until tested on humans, and some discuss their personal experiences with other treatments.

      Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
