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.\u003c\/p\u003e\n\u003cp\u003eWhat 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.\u003c\/p\u003e\n\u003cp\u003eLeave 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.\u003c\/p\u003e","brand":"Olaplex","offers":[{"title":"Default Title","offer_id":58507273896268,"sku":"OP4PSH250","price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/7834\/3500\/files\/2000_PNG-N4P_250ML_PDP_3000x3000_1000x_b1411059-0ed8-41cf-b256-e389da91053b.jpg?v=1787336484","url":"https:\/\/zenvy-beauty.com\/products\/olaplex-no-4p-blonde-enhancer-toning-shampoo-8-5-oz-250-ml-for-blonde-highlighted-grey-hair","provider":"Zenvy Beauty","version":"1.0","type":"link"}
