In true mermaid fashion, these waves do tend to look best on medium to long hair; you want to have enough space to show off the consistency of that curl pattern, which is what makes the end result so cool, points out Hershberger. (Ideally, we’re talking at least shoulder-length or longer.) That being said, as long as your hair can hold a curl, pretty much anyone can rock mermaid waves. Intrigued? Now’s the time to take this style for a test run. Breezy and fun, mermaid waves are also super versatile with lots of different ways to play and make the look your own. They look great pulled up into a high pony with a few face-framing pieces, or worn half-up, half-down, and with either side or center parts, says Hershberger. Ready to channel your inner mermaid? Here’s how to create this trendy style.
