I’ve tried a lot of shampoos, and Kérastase is by far my favorite. It leaves my hair feeling clean, soft, and healthy without drying it out. I’ve noticed less frizz and my hair looks much shinier. It’s definitely worth the price, and I always go back to it. Highly recommend!

I recently tried this product and, unfortunately, it did not meet my expectations. It was neither useful nor helpful in addressing the purpose for which it was intended. The features did not function as advertised, and I found no practical benefit from using it. Overall, I cannot recommend this product based on my experience, as it provided little to no value.

This is the holy grail for aging hair ! I have long blonde hair and I’m in my late 50s , having long hair has been a challenge due to breakage and my age , this shampoo is a game changer! Soft and long now love it

I don’t usually leave reviews, but this product is insane!!! I’m 4 months postpartum and my hair started falling out. I had doubts about buying this because it’s expensive, and I was worried it wouldn’t work. But holy grail!!! It lessened my hair fall after just a week of using it. All I can say is I’m satisfied!! Definitely worth buying. Thank you so muchhh!!! im so happy!!

[I received this product in exchange for my honest review] This shampoo feels like an all-in-one treatment, it makes enough foam which makes the hair super clean and the whole line smells exquisite You have to try it

[I received this product in exchange for my honest review] Not exaggerating, the Keratase Chronologiste line is my new favorite and go to. I used the line (shampoo, conditioner, and overnight youth serum) for almost 8 weeks before writing my review. This line has completely changed my hair. My hair is much more shiny, you cannot see as much breakage, and I personally feel like it looks like 1 million bucks. The first time I used the shampoo, admittedly it made my scalp feel a little dry and slightly itchy. But I decided to keep trying it and in a short amount of time, that stopped. The shampoo gets my hair clean without stripping it of its natural oils, it lathers up rather nicely, and it smells absolutely divine. This line has a nice light rose sent, and it makes me feel a little fancy while using it. I would shower most of the time at night and would apply the youth serum before going to bed on dry hair. While this line is a little bit more pricey, it does last a very long time. I was a little surprised by how long it has lasted me with the smaller bottle sizes. The shampoo truly does go along way though. So with that, I feel like this line is a fairly decent value for the amount of time at last as well as the results. I will for sure be buying this once my other hair products are out.

Lo amé!! Deja el cabello súper suave, brilloso, huele rico. Ya es de mi línea favorita. 10/10

New go to shampoo. It’s so luxurious and when paired with the mask, my hair feels so much healthier

I've been using this shampoo for a couple of months and love it. I've had very fine/very thin hair my whole life and my scalp gets oily pretty quickly. I've recently been diagnosed with scalp psoriasis by my dermatologist, which is controlled by medication. Due to all of these issues, I'm not able to go long periods of time between hair washes and my dermatologist (and scalp) tell me I should wash my hair every day or every other day, I very seldom go any longer without washing. I'm also highly allergic to floral scents and can't use things on my hair and skin that have strong fragrances. I used Kerastase for a long time years ago but over the years changed to try new products. In the past few years my scalp issues started so I've had to adjust what I use based on scents and how oily/ dry they leave my scalp. When I came back to Kerastase last year (I had no issues with it in the past) I started with Nutritive Bain Satin, which I LOVE. It left my hair so nice and soft, but it's a bit heavy and oily for my hair type and has a slightly stronger scent. I changed to Chronologiste because it's good for what my hair currently needs. I love this shampoo. It's drier than with Bain Satin but it's not a clarifying shampoo, it's much less harsh but definitely makes a difference keeping my oily scalp at bay. I use it every time with Matrix Instacure hair mask for conditioner and my hair feels great when I get out of the shower and with air drying and heat styling. The other 2 products in the Chronologiste treatment line help to restore moisture and have other benefits but I'm not using those products because, even though the smell isn't overpowering as a shampoo, I feel that if I use both of the others, it will give me headaches from smelling it all day. It's more of a clean, green scent but does have light floral notes. I've also washed first with Chronologiste then washed right after with Bain Satin, and that adds moisture, I do that about once every 3 or 4 washings.

I really love this hair care line it’s a thin hair girls dream , it leaves my hair looking a feeling so full and soft , along with smelling amazing also. It’s a little on the pricey side but so worth it !
