I think I’ve exhausted all the blonde toning shampoos in boots now! This blonde toning shampoo is good foe toning out the brassy tones but it leaves your hair VERY dry and doesn’t do anything to protect any other artificial colour in your hair. I would recommend the use of this but only of followed by a strong conditioner or treatment. It also says on the bottle not to leave in hair for a prolonged time, which indicates it’s strength. Therefore blondies, Use only on brassy tones if you need to!
