Great product!
2nd purchase of this product! I have damaged hair and it always feels healthier with every use! I feel it also helps with smoothness as I have extremely frizzy hair! Only thing which is a let down is the price unfortunately!

Don't believe the hype!
I followed the instructions, but this product left my already dry hair even drier. I honestly don't understand the hype. The amount of product provided is ridiculously small for the price and feels like an insult to consumers.
