Development of a Spectrophotometric Method to Determine Minoxidil by Diazotization-Coupling Reaction with Sulfanilic Acid

The conversation discusses the "bleach test" for minoxidil, where minoxidil turns yellow when mixed with bleach. The user tested liquid minoxidil, rogaine foam, and minoxidil tablets, all of which turned yellow, suggesting a reaction specific to minoxidil.

Noxidil from Zeemoreuncle appears legitimate based on a bleach test with oral minoxidil tablets. The test results showed an instant color change, suggesting the product's authenticity.

The conversation discusses the uncertainty of the legitimacy of minoxidil products in the EU market and mentions baricitinib as an approved, but expensive alternative. A method to test for real minoxidil involves mixing it with bleach to see if it turns orange or brown.

The conversation discusses the use of pyrrolidinyl diaminopyrmidine oxide (triaminodil) compared to minoxidil for hair loss treatment. The user is considering switching from 5% minoxidil to a product containing 5% triaminodil.

Minoxidil's effectiveness varies due to differences in sulfotransferase enzyme levels in the scalp, affecting people with conditions like ASD, liver disease, and androgenic alopecia. Treatments like topical tretinoin, microneedling, and using minoxidil sulfate instead of regular minoxidil can improve results for those with low enzyme levels.

Alcohol-based minoxidil absorbs better but can cause irritation; non-alcohol-based is gentler. Topical dutasteride shows promise but needs more research; low-dose oral minoxidil (0.25 mg/day) is effective with fewer side effects. Ingredients like Procapil, Redensyl, caffeine, and Anagain in shampoos have limited evidence; ketoconazole shampoo can help when used 2-3 times a week with other treatments.
