I've used the mask on its own and it's great. A really thick quality hair mask that really helps my thick and frizzy hair. It would have really helped if the set came with a mixing bowl, gloves and spatula. Had to source these myself. Personally I don't really think it needed a separate "dye" why didn't they just make this already combined? Just makes the whole thing a bit of a a faff but the results aren't bad.

This is an expensive set but really does make a difference to highlighted hair.

I really love kerastase. It's a excellent product for my hair which is an absorbent mass of fine hair and so I am constantly fighting the frizz with any damp or humid weather. Kerastase reflection and architecte really help. I have used the masque which is really creamy and deep conditioning but have not yet used the colorant as want to make sure I get the measurements right. Instructions for use include a kerastase pot and spatula to make life easier but this is not available with the sale of this product! It doesn't mean it's not useable I just have to prepare a little more.
