Expensive, but works!!!

I received a sample of this hair protective fluid with a Sephora purchase. I wasn't sure it would do anything for me, but was very pleasantly surprised with instantly soft, frizz free, vibrant hair. (I have crazy Brazilian untameable hair) I had recently lightened my hair and have been finding it kinda rough and lifeless looking. I've been applying all kinds of oils and products trying to get some softness and life back. I thought, why not! I applied this after shower with my usual leave in conditioner and my hair felt immediately soft and smooth. After it dried, my hair looked better then it ever has!! I usually have to stack 5 products just to get my hair to behave! I'm instantly in love with this! The only drawback is the price
