3 Out of 3 Celebrities Agree: Little Mermaid Hair Is 'In'

Are we really doing this? Yes, it looks like we are. Little Mermaid hair is officially "in," according to Rihanna, Blake Lively, and Scarlett Johansson. To achieve this look, soak your hair in red Kool-Aid, brush with sea salt, and rumple to taste.

Little Mermaid hair is popular with females who grew up watching Ariel moon over Prince Eric and Franka Potente run around Berlin in a bad bra. If you are a 20-something female and secretly like this trend, do not feel ashamed. It was imprinted upon you at a young age.
