Just average
[This review was collected as part of a promotion.] The smell of this shampoo was not pleasant. Compared to the many shampoos and conditioners kerastase has to offer this one is average at best.

The best shampoo I’ve used
[This review was collected as part of a promotion.] Omg this shampoo has been awesome not only for me but for my daughter as well. We used it for about 3 months and we saw the change, but our hairstylist recommended to switch it up for the black bottle so our hair doesn’t create a resistance to this product and then we will go back to this one. I’m crossing my fingers the black bottles are as great as this green ones.

Nice. Silky.
Nice smell, leaves hair silky, but I do notice my hair gets oily faster than in did with other kerastace shampoo.. likely because this isn't as stripping as others. So I do have to wash more often.

Disappointed
I’m disappointed. This is a luxury brand. I’m paying top dollar to make sure I get the best ingredients and quality for my hair. All my order of shampoos came in with dents. I compared it to my old bottles. I don’t know if your company is using a thinner plastic bottles or what may cause this, but I seriously hope the formula hasn’t changed. I sacrifice paying for other things so I can buy Kerastase. A woman’s hair is her crown. I want the best and I should expect it from Kerastase.

I have been using this shampoo with the matching conditioner. It’s not bad, but the smell isn’t as good as Chroma Absolu. The scent is very mild and does not last. Chroma made my hair feel super soft. This makes my hair feel dull, not luxurious. Not worth the money, would not buy again

Wonderful Product
[This review was collected as part of a promotion.] I like to enterchange this shampoo and the Bain Densité Shampoo. They are both great for my aging, thin hair. Both give it strength and make it look healthy and thicker.

Worst shampoo Kerastase makes
I've used a couple dozen Kerastase products, and this is unquestionably the worst. The shampoo is thin and runny, and I have to use 2-3x the amount to get my hair clean than I've had to use with any other Kerastase shampoo. It smells amazing and I love the conditioner and mask, so really a shame.

Not as good as I expected
I was using another shampoo from Kerastase and I loved it, I wanted to give this one a try but it gave me dandruff after a few uses and I bought the big one, sooo disappointing.

Okay
**Product:** XYZ Hydrating Hair Mask
**Review:**
I recently tried the XYZ Hydrating Hair Mask, and it exceeded my expectations! My hair is naturally dry and prone to frizz, but after just one use, it felt incredibly soft and smooth. The mask has a rich, creamy texture and a pleasant scent that isn’t overpowering. I left it on for about 10 minutes, and it rinsed out easily, leaving no residue. My hair was noticeably shinier and easier to manage, and the hydration lasted for days. I highly recommend this product for anyone looking to revive dry, lifeless hair. It's a game-changer!

Bain Extentioniste shampoo
Unfortunately the smell didn’t impress me!
But my hair was shiny. The worst part is that I got dandruff after two uses. Sad.

Too much perfume, how about shampoo?
Irritating perfume, threw it out. I wish you used no fragrance or natural fragrance so it is not so irritating.

A real delight
It does not lather for me personally, at first when washing it it felt as if it was DRYING my hair but after i finished washing it, my hair wasnt feeling dry, just normal! And it make my split ends dissapear, my hair feels as light as a cloud and i love it! The smell could be a littler bit better, i wish it would smell like the kératase elixir hair oil!
