Underlayer Hair Color: 7 Ways to Rock This Trend

Jazz up your look with a sweet surprise hidden under your hair.

Have you heard of the underlayer hair color trend? It consists of hair colors placed at the inner sections of your hair. It’s quirky, and it adds character to your look. With an undercolor, you get to wear your natural hair color (or any color for that matter) on the outer sections of your hair. But once you tie your hair in a half updo or when the wind blows through your hair, a hidden hue gets revealed. This will surely spark “oohs” and “aahs” among your friends and be a conversation starter.

If you want to try an underlayer hair color, here are some ideas. Check them out.
