I want to dye the tips of my hair a cotton candy pink. I have never dyed my hair before so I am doing my research. All of the dyes that I like say that you need to bleach your hair first. I have really dark brown hair (it looks black) I'm fine with it being a shade or two lighter but I don't want to have it be blonde or a white platinum.. are there any dyes that I can use without bleaching my hair?
