This 'Hair Tattoo' Trend Gives You An Edge, But Only When You Want One

Peek-a-boo.

As much as we love experimenting with our looks, some of us have corporate jobs and (sadly) can't casually rock a green mohawk on a Monday morning at the office. But even if life gets in the way, there are still fashionable things we can do with our hair to express ourselves. 

Say hello to undercuts. Many refer to these incorporated hair designs simply as "hair tattoos," and while the look gives you an edge, it can also be easily hidden by wearing your hair loose if you're simply not feeling it that day. Now that's a tattoo even your mom would approve of.

Great way to express yourself? We sure think so. Scroll down to see some of our favorite looks.
