I used to use this and for some reason stopped and tried other things. I'm happy and relieved I'm using it again, because it works! It seems to do an excellent job providing heat protection while also keeping my hair soft and manageable. It's slightly pricy for a relatively small bottle, but you only have to use a bit, so it will last forever. I personally like this a bit better than Biosilk, for I think it does a better job without making my hair greasy looking at all.
