If you are thinking about dying your hair black, think again. Unless you would like to wear this color until it is totally grown out, meaning until your hair grows enough that you can cut it off, your best bet it to use a dark brown instead of black. I have used black on and off for years and decided to go blonde again. This time, breaking the blue base was not so easy. In the last five days, my hair has undergone seven chemical services and about twelve conditioning treatments. It is not even finished yet. I know what I am doing and take it from me, find the darkest shade of brown and be happy with that- to everyone else it will be black.
