Good. Less shampoo needed.

Love it. Made my hair lighter. Easier to style.

I used this once a week before the premiere shampoo to give my hair an extra treatment when I had time at the weekends. It helps my dry, blonde, highlighted hair a lot!

This really helped my hair get rid of any extra product lingering in the scalp. My hair felt so soft and clean after using. Using once a week for a hair cleanse.

Makes my hair smooth and very soft even after the first use. Lovely scent too.

I really love the feeling this product gives to my hair. Hair felt more soft after even the first use. I love how easy it is to use. The fact, that you do not need to rinse it after application, but just go in with the shampoo, saves me time and effort.

Had never used a pre-shampoo before. My hair feels great after a full wash!

My hair feels great after using this & the full range!

After washing, my hair is nicely shiny, soft to the touch, and looks healthier

really like this shampoo and would definitely recommend it. It works well for all types of damaged hair, and as someone with blonde hair, I’ve noticed it leaves my hair feeling soft, healthy, and more manageable

Absolutely loved this shampoo. my hair is dry and quite damaged but even after the shampoo alone I noticed a big difference

Kérastase nevers disappoints, quality products & leaves hair feeling like you left the salon

Amazing product, I used it in conjunction with Kerastase Premiere Shampoo and conditioner, apply to damp hair and leave for 5 minutes before applying shampoo. it left my hair ultra smooth and shiny, genuinely unbelievable result, i will definitely be investing in this product.

After just one use, I am already a huge fan of this shampoo, my hair looks and feels fabulous. My hair looks strong, silky and smooth. Didn't need to use any straighteners and curling irons to smooth unruly hair. will definitely purchase again.

Big fan of Kérastase products & the decalcifying shampoo did not disappoint. It smells delish, its thick & creamy, used only once so far & am delighted with results, my hair is thin & bleached & is in dire need of help, only complaint is it could be too rich for my oily head so will be used as a treat once or twice a week

Highly recommend this treatment if you’ve got dry or damaged hair! My hair has never felt and looked better. Can’t wait to get the full range

My hair is dry and brittle and this shampoo has made such a difference. Smells amazing and leaves my hair feeling light and hydrated!

The Kérastase Pre-Shampoo Treatment helps nourish and protect hair before washing. Use a small amount, applying it to the lengths while shampooing the roots. It adds shine, reduces frizz, and makes hair smoother—great for dry or damaged hair.

The Kérastase Premier Shampoo is a little luxury you can enjoy at home. You really don’t need much—just a small amount does the trick! It leaves your hair looking super shiny and feeling smooth. Also great at supporting new hair growth.

I never used a pre shampoo treatment before but I did find that it worked well with the shampoo too leave my hair feeling very refreshed

My hair felt really light and fresh after using this shampoo, I also found my hair a slightly easier to style after using this treatment system

This shampoo is divine.. beautiful smell & leaving your hair silky shine finish

Excellent choice of treatment for hair .
Leaving it smooth silky & good condition after use .
Smells beautiful 😍

I would recommend this pre shampoo if your hair is damaged in any way and to prevent breakage I put it on wet hair and let it sit for 30minutes works really well with the shampoo and conditioner from this range which are excellent . A lovely treat for your hair- good for blondes.

I love the Kérastase products but this one in particular I would say is the best,. My hair felt so clean. and fresh, and when used along with the Premiere conditioner its fabulous, I would highly recommend this product ..Love it

So easy to use, made my hair feel so silky in the shower! Can't wait to see the results after a few uses

This shampoo smells gorgeous, very creamy and lathers nicely

I have just started to use this Shampoo and loved it straight away. It made a huge difference from the first wash. My hair smells fab and is so soft.

I love this shampoo. The smell of it alone is just divine!!

I love it , really good product , my hair looks healthy now
