“During my last vacation, my hair turned an ugly yellow color. How to get rid of it?”
It's very simple: we advise you to wash your hair with a delicate one, blond foam toning agent with a shade of ash (np. Poly companies, LOreal). However, you should always keep this in mind, that hair previously dyed blonde is porous and absorbs the dye faster than healthy and undyed hair. The duration of the preparation's action should therefore be a little shorter than that stated on the packaging, so as not to dry your hair too much.
