Underlights blue and PurpleWhen you think about underlights, you probably have flashbacks to yourself in the 2000’s decked out in a flippy Abercrombie & Fitch skirt and slogan tee with zebra stripe-like hair. You thought it was the definition of cool to have the under layers of your hair completely contrast the ones on top. Times have changed. You may cringe when you think about the look now, but don’t completely forget about the look. The new underlights hair colors may have you considering trying the look once again. Our old underlights have been given a modern rainbow makeover. If you do not want the commitment of a full head of unicorn hair, or you couldn’t get away with that look in your conservative office, some well-placed underlights are the solution. That’s the reason they are now also being called “secret rainbow hair.”
