I have the smoothie but I don't use it in conjunction with it because both contain a lot of humectants so too much can cause me frizz! I am still trying to learn the whole moisture/protein balance lol.
As far as KCCC goes, I do like it but, I won't buy again bc of the price. However, I can say a little goes a long way meaning it lasts you a good while so then it kind of makes the price worth it, but not? lol I can't seem to make my mind up! lol
