You've heard of mermaid hair -- long, flowing, often turquoise-hued locks that look perfect for a day at the beach. But how about merman hair?

One of the latest trends on Instagram is #MermanHair, a showcase of dudes who dyed their 'dos fluorescent colors in honor of those mythical sea creatures made famous by Ariel in Disney's "The Little Mermaid."

With tresses that would make Ursula mad with jealousy, the men of #MermanHair are redefining what men's hair looks like. And while we do appreciate the dedication here, dudes, if you really want to be a true merman, start combing those locks with a fork a lá Ariel. See more colorful 'dos here.
