Been using it for about 3 weeks now.. I was having some bad shedding after the EF contest for about a month during my PCT. I only use it once a day (sometimes even miss a day if I'm in a hurry in the shower) Since using it I've had NO shedding whatsoever, and my hair is way more thick and full. I can't tell you if any has regrown, as I haven't taken before and after of a location to compare.. but I know it's definitely thickened what's left.
I can't believe how little you have to use, less than a dime and it lathers and covers the entire head easily. I LOVE THE SMELL. That mocha smell makes me hungry. Even if I miss a day, I'll catch a whiff of it every once in a while. Potent stuff. I even stopped using conditioner.. the stuff works so well my hair doesn't seem to be as dried out.
