UV Spectrophotometric Stability Indicating Method Development and Validation for the Determination of Finasteride in Bulk and Dosage Form

The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.

RU-58841 does not dissolve well in common Minoxidil solutions due to water content, requiring a 70/30 ethanol/propylene glycol mix. Users report using separate solutions for RU-58841 and finasteride/Minoxidil for better results.

A user noticed a color change in their hair loss solution containing minoxidil, finasteride, retinoic acid, and hydrocortisone after storing it for several months. They are concerned about the effectiveness of the solution due to potential oxidation.

The user wants to reduce their dose of topical finasteride to 0.1-0.2mg and is considering mixing 0.2ml of their current finasteride + minoxidil serum with 0.8ml of a minoxidil-only serum for better scalp coverage. They are asking for advice on whether this method is effective or if there's a better way to dilute the finasteride solution.

OP used HIMS hybrid tablets containing 1.1mg finasteride, 3mg minoxidil, and 2.5mg biotin, showing significant hair regrowth after initial shedding. OP experienced no side effects and plans to continue treatment.

A 36-year-old started using 0.5mg finasteride and 2.5mg oral minoxidil daily for hair loss, reporting positive results without side effects. Despite criticism about photo lighting, the user remains optimistic about continued improvement.
