In on my second bottle purely because I bleach my hair and have heard this does amazing things for repairing damage... I think it's ok, not sure what I expected but maybe more for the price point: if you use to much on fine hair or leaves a thick residue so you need to be sparing with the amount used.

This is a NO
I don’t understand this product. I’m supposed to use it without conditioner, but my hair was like grass and this product did not make it smooth and am I supposed to walk around with frizzy hair for plus it’s insanely expensive three days until my next wash?
