Matrix ColorInsider hair colour is, unlike traditional permanent hair colours, an oil based colouring system designed to give sharp, true and saturated colour results. ColorInsider is a no-ammonia, precision permanent colour that maximises high-definition colour results with minimum stress to the hair's cuticle for outstanding shine. The beautiful shade palette offers vibrant reds, cool modern neutral tones, and rich browns, all with 100% grey coverage. Plus, since there is no ammonia (which means no odour!) hair will be smoother and shinier than before.
