With RU being so expensive, i think i'll just stick to the instructions the company give me (just recipes for people who it's worked for)
It uses perfumers blend, and some ppg, i believe. Stax used this, after a month had his temples fill in (though he was using a lot of other stuff), then hasnt posted since. Apart from one little argument ending with "who cares, my hair is doing great, i'm off"
I'll experiment with spironolactone, fatty acids, phenytoin perhaps, topical finasteride, but with something as expensive as RU, i'm being more conservative.
