I've decided I really want turquoise hair, and as my hair is dark brown right now that means bleaching. In the past when I've dyed my hair I haven't had to worry too much about the bleach turning me ginger, as I've only ever dyed it red or pink. Obviously for turquoise I need as white a base as possible. Which is going to be hard when my hair has very red undertones.
I'm confident dying my hair at home, but I'm wondering a few things,
a) would it work out cheaper at home or at a salon?
b) are there any tricks for doing it at home?
c) how do I stop it frying my hair?
