I have a love/hate relationship with this stuff! My curly haired clients absolutely love it! But only if they're straightening or smoothing out their hair. Do not be fooled by the name of this product. It does not relax curl. All it does is seal down the cuticle to make it EASIER and look shinier when going for a straight style. If you have straight hair to begin with, you can put a pea size amount in your hair and let it air dry or blow it out for a shiny silky look all day. My beef with this product is that you can definitely overdo it. More than a pea size amount and you're going to need to wash your hair. I hate to complain about needing only a tiny amount, because this stuff lasts forever, but ever since I felt the drag and sticky mess after overdoing it, I'm hesitant to use it! I haven't been a huge fan of the Davines styling products over all because of this same problem. Everything seems to only work with the exact concoction, air temperature, humidity, sunlight and cups of coffee.
