I've always known bleaching was bad for your hair. That was definitely something I had to consider before I went so dark. xD It's hard to go back to my natural color from black.
It's almost impossible, I don't recommend it. I had mine done in a bleach bath to try and go back to my natural colour, and now it's completely wrecked.
If you're going to do it, try getting lighter foils put through it periodically.
