Peek-a-boo hair is all the rage right now in hair fashion. Luckily, it is not hard to dye your hair in the peek-a-boo style. With a peek-a-boo style, either the bottom layer is dyed a different color from the top layer or different colored highlights are made throughout the hair. The color is only visible when it shows through the top layer of hair. The peek-a-boo look will work on any type of hair, in any color. You just need to decide if you want a wild color like hot pink or a natural color like black.
