A very good product

I have damaged hair and hair extensions to add to length and fullness. This mask works well for both. It makes my hair feel softer and have more shine than without. I am not wild about the scent .

Smells great

This mask smells great! I gave 4 stars because for my hair it didn't helped. Very dry, though it helps my hair not break.

Scent is way too strong!!!

It makes my hair soft and strong. The scent however, is WAY TO STRONG!! I work in an office with a "scent free" policy, and was told the strong scent does not comply. Too bad...good product otherwise...

Just no

Did nothing to my hair. It’s expensive and not worth it. Waste of money.

Too thick!

I bought this because of how amino acid rich it is. However, the formula is too thick for my low porosity hair. Better for other hair types.

Made my hair WORSE

WOW. I can honestly say I'm not a picky person.. I decided to go 'big' and spend a bit more money on hair treatments. Reading all the reviews I went with this ketstase hair strengthening mask. Maybe my expectations were too grand, but this mask did exactly the opposite of what I wanted. Not only did it make my hair INSANELY FRIZZY but it also made it feel greasy and clumpy. At first I thought it was a fluke, but nope after 4 honest tries of using this product I got the same horrific result. Please save your money! This product could not only make your hair worse, but the smell is so gross and cheap! Never again.

The best of Kerastase

If your hair is in extremely rough shape, this mask is a miracle. It’s very thick, and will weigh down fine hair, but will be soft and shiny. I’ve tried all of Kerastase’s masks. This is the best for my hair.
