I tried this shampoo a few years back and it wasn't bad. For a while, it made my frizzy waves look really nice and elegant like I had just freshly curled them. However, over time, my waves started to straighten out more. I guess it's a good thing it wasn't as frizzy as before I used it, however, my hair lost that touch of uniqueness and eventually started looking more flat than healthy. I eventually stopped using this shampoo because of that. However, overall, the shampoo works great. The scent is great, and it stays there for a really long time and would be the perfect product for people looking to tone down some curls or maybe make them look more silky and refined. Effectiveness Nice for those wavy haired people looking to calm down or add a little volume to their waves. However, over a long period of use, my hair became a lot straighter. Scent Pleasant smell, but it doesn't make me want to fall in love with my hair. However, the scent does last a long time after you wash with it.
