Kleurneutraliserende shampoo L'Oreal Professionnel Paris Chroma Crème Blauw (500 ml)

This shampoo was recommended by my hairdresser. I dyed my yarn white blonde myself (see photo) and with this shampoo I really keep the yellow color out of my hair. You can do a long time with the bottle. The advice is also to use it once a week. Be careful because if you let it soak in too long, your hair will turn a little blue. And your hands also take over the blue. So massage in and rinse out quickly! Works really well.
