Kérastase Age Premium Masque Substantif - Treat Customer Reviews

I almost hate to admit it, but I spend about $100 or more on my hair every month to get it colored, cut, and blow dried. It's my one splurge.

My hair used to be very dry and brittle until I found this product. Kerastase does everything it promises to do - my hair feels and looks great since I've been using this.

It's added to my list of hair splurges - it's definitely a must have if you're of a certain age and color your hair!

I have long straight hair, not super fine, but definitely no where near course. This conditioner was the thing that finally got me to wash my hair every other day.
I was a daily washer before I found this. My scalp gets greasy, but my ends are dry. This conditioner strikes the perfect moisture balance. I use it daily.

It makes my hair reasonably soft, but I haven't seen any long-term benefits. It hasn't improved the thickness of my hair or the number of strands that fall out. Not worth the price.

I normally do not use a rinse or mask. It I love how my hair feels with this product. I have been using every other hair washing.

I purchased this product because it promised to help my dry, "aging" hair. First of all the smell was not so great. Secondly, I don't think it worked all that well. Honestly, I prefer the Kerastase Chroma Captive product.

I have thick, porous hair- and this line of Kerastase products is the best for adding softness and a healthy smoothness. This is a heavy conditioner- but it rinses clean. I love this and also the shampoo from this 'purple' line.

I bought this for my mom, along with the rest of the age premium line, and it seems to be working. My mom had been complaining that her normally dry, color treated, think, wavy hair was feeling ultra dry, light, thin, and beginning to shed WAY more than usual. Since using the age premium line, we both noticed that her hair seems fuller, softer, and less tangled. I've definitely noticed, since the first time she used it, that she's been shedding much less. It's quite a bit more expensive than other hair lines, but so far it has been worth it. I will most definitely keep purchasing this for my mother, as long as she's happy with it.

Great mask. Left my hair feeling smooth and shiny. I love that it didn't leave my hair feeling greasy! I will definitely be using it for a long time!

This product is great; I love it and will buy it again and again. It's the best hair treatment I have found.

My hair was damaged from years of coloring. This product truly moisturized my hair without making it appear greasy. I would highly recommend it!
