Amazing
I love to use this on my wet hair after washing. It detangles and leaves it super soft.

Nice
Heat protectors can be heavy and weight the hair down, but genesis defence detangle, provides some level of heat protection and remains light weight. Will buy again.

Definitely buy this
This product saved my hair and makes such a huge difference when I started using it. I have repurchased this several times and the texture of my hair changed so much after so much damage on my hair.

Overpowering smell
Unfortunately it smells like products you find the cleaning/household isle - furniture polish 🤔?! Such a shame because it’s a nice product. Please improve the scent.

Not for me
Did not do anything. Dispenser is awkward, hair was looking dull and I swear it does not provide any thermal protection. Would not repurchase, probably the worst Kerastase product.
