Shampoo's, if they work at all, are localized to the DHT receptors in the hair follicle - don't worry about libido. I'm vain, so when I started thinning (due to high Omega-6 use I believe - my fingernails went wonky at the same time ((cupping))) I bought a bottle of each of the 3 main players (Pura'd Or, Regenepure DR, and Lipogaine) and mixed them evenly for a 'Super Shampoo'. I then got a 0.25mm Derma-Roller (get 0.5mm, I'm moving up) and Perfect Hair 5% Minoxodil and Azaelic Acid Solution. My sh^t looks good, now
Those shampoos lather like a mofo, so while expensive at first blush, those bottles will last 6 months at least, I use the Pura'd Or pump bottle as the main container, and a half-pump does the trick. I don't know what exactly did the trick maybe all, maybe just one - who knows. I do know that with Generic Minox from Sams, I wasn't thrilled. But it does take a LONG time to fill back in, so stick with it - I now consider it like toothpaste, deodorant, etc...
