Overview

Not just a purple toning wash, this amika shampoo pairs brass correction for blonde hair with strength repair to cut breakage. It aims to cool yellow and orange tones while cleansing.

Toning and repair in one wash is a time saver for lightened hair. The listing is bare, without volume, pigment details or how long to leave it on.

Who it's for

Blondes who see warmth creep in between salon visits will use it to stretch their tone. People with natural brunette or untreated hair have no need for toning.

Performance notes

Toning shampoos deposit cool pigment that cancels yellow and orange, so contact time decides how strong the effect is. Leaving it too long on very light hair can tint it, while a quick wash gives a subtle cooling.
