Very nice

[This review was collected as part of a promotion.] Very nice leave-in treatment/protectant. Love all of the Kerastase lines, especially the Premiere, Genesis and Chronologist. My hair has never felt so healthy, strong and felt so silky smooth as after using these products. The masques are fantastic!.

Did not work.

I have used the leave in Discipline Keratine Thermique Heat Protecting Cream four years and it worked very well on my fine thin hair to control frizz. I am extremely sorry to see that it has been discontinued. I tried the spray and it does not work. I also tried the masque and it was too heavy for my fine hair.
