I have been using this for several months, and I like it. I put it on before bed, wash my hair in the morning and my hair looks healthier, smoother but not flat. I have thin, dry, shoulder-length, highlighted hair which is hard to keep from looking flat and scraggly.
I live in a very humid climate, so I am always looking for new products to control frizz. I used this and found my hair was smoother, and I had less little flyaway hairs.
