I used the Curls Rock Amp for several years many years ago, cocktailed it w/a gel. I tried it again just recently and it felt like I was putting glue in my hair. I returned the the product and tried out the root boost, hated it. I had the worst hair day ever! But, it's quite possible I didn't use the product correctly or used too much. I've heard only use curls rock amp on soaking wet hair, but my product rep uses it on hers when it's 95% dry. Good luck.
