Kerastase - Fusio Exfoliating Scrub Stories

It’s lovely to get a deep care hair treatment as a part of your hair salon visit, whether it’s an add-on to a haircut, color or blow dry. The problem is, conventional hair treatments require several minutes to penetrate. You may need to sit at the shampoo bowl or under the blow dryer to get the full benefits, and you may worry that the formula is too thick, that it will weigh down your hair. So you may choose to forego the hair treatment, simply because you don’t have time.





Well, these are no longer concerns. Using advanced Lamellar technology, K Water instantly activates upon contact with water to smooth out the hair fiber, creating a flawless, glassy surface. Amazingly shiny hair emerges that's fluid and weightless. It’s a total transformation to perfect hair—in just a flash.​

THE HAIR TREATMENT​

Unlike a conventional hair mask, where caring agents are emulsified in a liquid cream, K Water’s healing power is dissolved in a clear liquid. The formula acts instantly upon the hair fiber and rinses off easily for a weightless finish. Your hairdresser applies K Water after shampooing and rinses it off immediately before styling as usual. The hair is perfected in a matter of seconds. The immediate result is unbelievably sleek hair with a glasslike shine - K Shine.

THE FORMULA

A light, clear liquid, K Water is actually devoid of water. It is a combination of glycol and caring agents. These caring agents are instantly signaled by water to attach to the hair’s surface in layers to create a smooth finish.

Protected from hair breakage and easier to comb, blow dry and style. It is soft to the touch and highly reflective, for a glass-like shine. You'll leave the hair salon with sleek hair, and not a minute wasted.​​
