Kerastase Blond Absolu Bain Ultra-Violet Purple Shampoo Review

Kerastase builds the Blond Absolu story on hyaluronic acid for the hair fibre and edelweiss flower for softness, with vitamins C and E printed on the bottle front. That care layer is the real difference from the functional salon purples ranked below it: the wash feels like a treatment shampoo that happens to tone, rather than a toner that happens to wash. The base is sodium laureth sulfate, stated plainly in the ingredient list, so buyers running a strict sulfate free routine should read this as a considered exception or choose the Pureology instead.

The published schedule is weekly use, a minimum of 2 minutes on the hair and a maximum of 5, with the brand adding that a hairdresser can fine tune frequency to the level of bleach. Owners return to a consistent set of themes: blonde that looks cooler and more luminous without tipping lilac, hair that feels conditioned after a toning wash, and a bottle that lasts because a weekly dose is small. The complaints cluster on stained hands without gloves and on very porous ends grabbing extra colour when the full 5 minutes is used carelessly.

Skip this shampoo if your warmth is orange and your hair is brunette, because that is blue shampoo work and no prestige purple will do it. Skip it also if sulfate free is a hard rule, or if your brass is extreme and purely yellow, where the cheaper and stronger Fanola No Yellow is the more direct tool. Everyone else in the blonde and grey family is looking at the benchmark.
