Hello my lovelies. I have dark blonde hair, with the obligatory silvers here and there. I want to do my hair red. The colour I want to do is a Schwarzkopf Brilliance red. Having not had much experience with colouring my own hair, should I get a friend to do it for me? And what do you use to get the colour off where its not supposed to be, like on your neck if you miss?

Thanks!
