I love it

[This review was collected as part of a promotion.] It really does its job. Love the smell the effciency helping to heat protect my hair everytime I use the blow dryer.

Wasted money

This product isn't very good; I waited a while before writing a proper review, but it leaves my hair frizzy. Honestly, there is no difference between this and a cheaper product, even though Kérastase is supposed to be a premium line. I think I’ll invest in the standard L’Oréal line instead.
