Validated RP-TLC Method with Densitometry for Assay of Finasteride in Simple Pharmaceutical 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%.

The conversation discusses adjusting the isopropyl alcohol, propylene glycol, and water ratios in a topical finasteride solution for better scalp comfort and less dandruff. The user considers using 20ml IPA, 25ml PG, and 15ml water in a 60ml bottle, moving away from mixing finasteride with topical minoxidil.

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.

OP is considering using Stemoxydine or the Ordinary Multi Peptide Hair Serum as a carrier for topical finasteride, avoiding minoxidil due to palpitations. They plan to crush finasteride pills into a 30 ml solution.

Finasteride pills don't fully dissolve in a DIY topical solution due to fillers, resulting in residue. Users suggest shaking well before application and note that commercial solutions appear clearer.

User creates 0.1% topical finasteride solution using Alfatradiol Avixis base. Seeks help to ensure alfatradiol base dissolves finasteride.
