This product has changed my life... I feel so much confidence since I've had it. I was tired of people looking at the back of my balding head and the top. This adds hair fibers to existing hair. It covers everything on.my balding head. Sometimes it takes some time in the morning to do just like you have regular hair. You have to get a hang of the pepper shaker style. I have tried the other tools they offer, but as a primery bald person that just seems to not work as well. The pump just blows powder all over. Most people don't even notice there's a difference, and they think I just dyed my hair. I sleep with it at night and leave it on for almost about a week (5 days) then it starts to get a little itchy. Has to be touched up everyday. I.spray w hair spray n blow it w blower to hold. I have read that you can get it wet and when I go in the shower it doesn't seem to come out right away... but I haven't quite tested that theory out yet. Also cut it when trimming up like real hair. It's Worth the try for any guy n gal, n would be excellent for guys w fullet hair but thinning.
