Lamellar Exclusive Resurfacing Hair Treatment

Size: 400ml / 13.5fl.oz.

Kerastase K Water is an exclusive hair treatment for all hair types designed to deliver superb softness, shine, and hydration to hair. It contains no water, but it is a unique combination of glycol and amino acids activated upon contact with wet hair. Due to its lightweight, water-like consistency, K Water doesn't work to repair damage deep within the hair follicle but is applied for more of a cosmetic outcome. Kerastase K Water is based on new Lamellar technology that instantly targets only the hair fiber areas that need nourishment and stays away from places that don't need as much care. This allows the treatment to create an astonishingly smooth and silky finish with perfect shine and never overweighing or undernourishing the hair. Kerastase K Water resurfacing treatment will prepare the hair for any styling and blow-dry procedure, delivering immediate results of an incredibly sleek and fluid hair finish with magnetic shine.

    Kerastase K Water

    Posted by Emily Magyar on 1st Aug 2022

    I buy this 2-3 times per year, after trying it in a salon. It is hands-down the best product I’ve ever used on my hair. It makes my hair smooth, glossy, and smells so pretty! Highly recommend.

    Great shine!

    Posted by Susanne on 21st Mar 2022

    I recently stopped dying and grew out my gray hair. I was missing the shine I used to get from hair dye. The other only ways to get shine are from oil (which I hate), or a lamellar product like this. I’ve tried several lamellar brands, and this one is the best. I use it a little differently from the directions. I put the product into a misting bottle and mist my hair after shampooing and towel drying. I comb it through and leave it in. No rinsing. I use much less product this way…which is great, because this is an expensive product. I get shine for days. I don’t need to use conditioner or any styling products…I just use shampoo and K Water…which makes the high price easier to tolerate. My only criticism would be the strong perfume smell, but I find it goes away once my hair is dry. I can’t praise this product enough. No build up. No greasy look. Just shine and silky hair. Brava!

    I was offered this product in-salon a couple of years ago and would regularly have it done at the salon every month. For days afterward my hair would be shiny, bouncy and feel and smell amazing! I decided to purchase my own bottle of it five months ago, and it was the best decision! I put it into a small spray bottle to ensure even coverage and that I don’t waste any of the product. I wash my hair twice a week and I use a little of this each time. It doesn’t seem to have any build up and I love the way my hair feels! Worth the money! I just bought my second bottle, so they last a pretty long time.

    This product was recommended to me by a friend, she had the treatment done at the salon. I received it couple weeks ago and I am speechless; this product is fantastic! This incredible conditioner works instantly, my shoulder length, medium-thick hair is silky smooth, glossy, and full of life. The scent is strong but once you rinse it out, the perfume smell is gone and it leaves nice warm luxurious aura on your hair. The bottle is large and the nozzle that comes with it (for application) is not very effective. I found it more efficient when I poured the K Water into a smaller 2oz bottle with a sprayer. This way you do not lose a lot of this expensive product and the K Water is distributed on my hair evenly. I highly recommend this product....I can't live without it :)

    truly does work

    Posted by Jennifer on 11th Sep 2020

    Super fast treatment to get "in-salon kerastase" look :) I tried it in my local salon first on my thin hair and I loved it. I thought that it will weigh my hair down but no, it added incredible silkiness and shine and my split ends were barely visible. I decided to purchase whole bottle here on VB site since I am purchasing my Kerastase here. This high-performance K water works great with combination with fusio dose....recommended!

    The only thing that has ever worked short of a very expensive salon visit. Goodbye frizz. Wonderful.

    Expensive but worth every penny! It fully meets my expectations; it instantly rejuvenates my dry hair and transforms it into beautiful and silky hair. I don't use a lot on my chin length haircut so I am pretty sure it will last for a long time. Definitely recommend it!

    This product is great! Works instantly on my coarse hair by adding amazing softness and shine. It completely changed the texture of my hair which made it very manageable, smooth with a little volume. The K Water smells great too and I am officially married to this product :) Highly recommend this!!!
