Not worth it

Used on fine damaged hair without noticeable results. Not worth the price.

I bought a larger bottle I was so impressed!

I used this when I wasn’t using the mask. It instantly softened my hair and helped the tangle and the product kept working long after a dried. My hair was not in the best condition going into my wash and honestly after using the K 18 shampoo and conditioner is so better but still not great. Using the heat bounce, leaving, made all the difference went back to the store and purchased a large eyes after previously purchasing the mini. shampoo and conditioner, but this heat protects practic made all the difference.
