It’s customary when dyeing hair especially to a lighter colour like blonde or purple to first bleach so that the lighter colour will be able to appear brightly on formerly black hair. However the process of bleaching hair is a very tricky one which, if not done right, can destroy hair. In lieu of that, hair brands have been coming up with
new formulas of dyes to be used without first bleaching hair.
I tried one of these hair gels which promised to temporarily dye my hair purple by simply applying it.

That's gorgeous! I liked your review very much. But what about gray hair? I've been reading this article and want to know what do you think about the methods described there. They also don't involve any bleach at all. I want to try concealer spray and 3D gel.
