 Hi beautiful, you know we're all obsessed with this mask. If you're a blondie, you know what I'm talking about. But did you know if you leave this mask on for five minutes versus 10 minutes, it does make quite a difference. If you have more of that yellowy, orangey, brassy hair, leave it on for a good 10. If you just need a little bit of toning benefits, just leave it on for a good five minutes or and look at the difference of the five minutes versus the 10 minutes.
