I've been using this product for a couple years now after my hair-cutter told me my hair was dry. My hair-type is asian hair, so it is relatively thick, and course. I've been told I have a alot of hair, and after it gets wet - it gets quite frizzy and it's not perfectly straight - there is a slight wave. So i was looking for a product that hydrated my hair. Though this says that it is for "severely damaged hair" - i definitely do not fall in that category as I haven't ever done anything to my hair (other than use a straightening iron maybe once a month for the past year). Basically, i think this product does a great job. I can really tell a difference between using it/not using it since without it, my hair isn't as silky. It leaves my hair really smooth and manageable. I use it every time i wash my hair and it doesn't make it any more oily than if i were to not use it. But i do notice my hair to be much softer and less dull.
