Two-toned hair is a coloring technique that features two distinct colors. These colors can be of your choosing, but adding blue is a great way to do this if you have naturally dark hair and want to give it an update. Blue and black blend well, and although this is a look that takes confidence to pull off, it is not as daring as other combinations would be; for example, black and pink. Adding the blue to only your bangs is also an excellent way to shift the focus there. Bangs are a great addition to any haircut because they can highlight your facial features and make you look younger.
