I have wasted so much money over the years on products that simple just do not work. And, of course, as I have gotten older, I have gotten cheaper. When I first saw this is my local drug store and saw how much they wanted for just a small bottle, I thought they were insane. Then it seemed like this product just kinda followed me around. I had never noticed it before but all of a sudden I started notice it everywhere. Well, finally I went to my local salon to get a cut and noticed that they were having a buy one get one free sale on this product. Finally! A deal even my old cheap butt couldn't pass up! I don't recall a time in my life to have ever given a 5 start review.. to anything... ever.. except this product. It's worth it's weight in gold. It has completely transformed my hair from this dried out frizzy mess it was for years, to a head full of strong, sleek, frizz controlled healthy hair. I ran out for about a week a few months back and asfter my first wash, I noticed the difference of not having it in my hair. Just like I noticed the dramatic change the very first time I used it. This product really is a 10!!!!!
