We all need a little self-care and what better way to take some time to yourself than with a trip to the salon? Getting a professional blow-dry is at the top of most women’s lists when they want a special treat or pick-me-up. However, time is precious and with our increasingly busy lifestyles, we all want results, and we want them fast. Thankfully, Kérastase has listened to our time-strapped prayers and introduced the innovative new K WATER in-salon treatment to bring your in-salon experience to the next level.

This breakthrough treatment replaces the conditioner step with no added ‘leave-in’ time. Using a global first, Lamellar Technology, K WATER delivers exceptional hair in a flash with instant and visible benefits. It transforms the surface texture of the hair, providing a luxurious fluidity, for hair that is shinier, softer, ultra-lightweight and full of fluid movement—in other words, everyone’s dream hair.

With such impressive claims, I couldn’t wait to try out the treatment for myself. I headed to Zeba on South William Street to put it to the test, courtesy of Kérastase.

The process itself was as quick as a standard wash and blow-dry. After cleansing my hair, my stylist, Jenny, applied K WATER in a zig-zag motion, to ensure even distribution. The water-like texture emulsifies on the hair with no activation time needed—the product gets to work immediately, only targeting the areas that need it, which means there’s no waiting around.

Afterwards, my hair didn’t need any conditioner or mask which was a first for me—my hair is prone to frizziness and knottiness so I normally apply conditioner, after shampooing, to smooth the ends. However, this wasn’t the case. The treatment was simply washed out and then Jenny got to work blow-drying my hair.


As you can see, the results speak for themselves. My hair looked shinier and smoother, without feeling weighed down. What I particularly liked about the treatment, though, was that my hair seemed to be less prone to knotting in the days following (long hair problems!) and the next time I washed my hair, at home myself, I could still see the effects—my hair was easier to manage and felt softer than it usually does after shampooing which gets a big thumbs up from me.

The K WATER treatment is available in selected premium professional salons nationwide with prices starting from just €8.
