Why is it important to thoroughly rinse all the hair color out?

It is really important to rinse all hair dye out because, for instance, if you wash your hair and you still have leftover dye remaining and you just leave it there for a couple of days you will start to notice it...not only you but people around you and that would be quite disturbing.

Then the hair dye also can damage your hair extremely bad if you leave it in because, you wanna know why: hair dye is a chemical and if it's left in way too long, trust me, that little hair dye will do major MAJOR damage and we don't want hair that's all falling out and torn or anything bizarre like that do we! Everyone I'm sure wants great healthy hair!
