Mermaid hairstyle is a term we're searching whether it's as part of planning a Halloween costume or not. Long, wavy, side-swept hair is always going to be gorgeous, no matter the time of year. There are so many options, and they're all fairly easy to try. All you need is a little bit of inspiration (we got you) and a few product recommendations (we have those, too). 

We scoured the internet and found a few select favorites on Instagram, from hairstylists and women in our community. Whether you're interested in fin-friendly costume, a bridal look, or a simple polished hairstyle for any event, keep scrolling. Below, find everything you never knew you needed for the prettiest mermaid hairstyle. 

Get a disco-mermaid vibe with long, '70s-inspired waves. If you have fine hair, apply a few spritzes of texture spray to add lift and hold to the style.

For a more spot-on Ariel from The Little Mermaid costume, opt for super-glossy, auburn hair. Whether it's your natural color or not (we suggest bringing this gorgeous photo with you to the salon as inspo), you can up the ante with a shine spray.

If your mermaid costume is chicer and simpler than it is over-the-top, try this long, half-up fishtail braided style. It's a bit more special than an everyday look but still easy to pull off (and doesn't include any dye). FYI: Mark Townsend uses mousse on dry hair post-blowout to achieve that ever-elusive Olsen lived-in look.

If you're really looking to get literal, go for a wet-look hairstyle—because, you know, mermaids live in the ocean. All you need is a shiny, strong-hold finishing gel, and you're good to go.
