Okay I usually use Directions White toner, (which does the job). but i thought i'd try something new. I left Crazy Colour Platinum Toner on for about an hour, on bleached yellow hair. I wasn't expecting much from it if i'm honest. 'cos crazy colour has always been pretty unpredictable for me, but the result was very nice. When I first washed it off my hair was Violet/pink, which is understandable after a hour. but after 2 washes and conditioner my hair was much more white. definatly got rid of the harsh yellow tinge. So I'd reccomend it, probably more then Directions white toner! - and my hair looks nice and healthy too. :3 -XTC-
