I tried minoxidil pills for a month and put on about 10lbs from a base weight of 107lbs (as well as getting hair all over my face and body). I stopped the pills because of the rapid weight gain and switched to the topical foam for a year with no results. I now started Viviscal for Women about 10 days ago and am feeling like the weight gain may be happening again. People swear by the results but I can't afford the extra lbs. I would switch to Viviscal Pro if it makes a difference on the scale.
