Olaplex No.4P Blonde Enhancer Toning Shampoo 8.5 oz / 250 ml - For Blonde, Highlighted & Grey Hair
Purple sits opposite yellow on the colour wheel, and that is the whole mechanism behind a toning shampoo. The violet pigment in No.4P deposits on the hair as you wash and cancels the warm tones that creep into blonde, lightened and grey hair between salon visits.
What separates this one from a standard purple shampoo is the bond-building technology underneath. Lightened hair is structurally weaker, so a toning wash that only deposits pigment is dealing with half the problem. This one works on the disulphide bonds at the same time as it tones, in a 250 ml bottle.
Leave it on longer for more correction and rinse sooner for less. Grey and white hair usually needs less time than freshly bleached blonde, so start short and build up.
