How much does it cost to dye your hair black and get bangs?

It depends on where you choose to go. Getting bangs cut isn't too expensive, you could probably get it done under $10. Hair dye is cheap at a super market, but since black is a hard color to do, I wouldn't do that. Getting it done at a salon is around $40-$60. It seems expensive, but it's worth it. Black can go horribly wrong, so you should probably get a professional to do it right. And remember that you can't go to a lighter color right away. If you choose to dye it again, you'll have to go one shade lighter at a time until the black is gone.
