Mermaid Waves Are In For Summer - Here's How To Get Them

By Franchesca Villar -
Mermaid waves trend blog

Some looks just define the season, and this summer, mermaid waves are taking over TikTok feeds, red carpets and beach holidays. With their soft, sculpted texture and breezy, lived-in look, they strike just the right balance between styled and undone. Imagine gentle ripples that move as you do - less glam curl, more goddess energy.

There’s no need to live by the coast or spend hours styling to get in on the trend. From heat-free hacks to clever hair styling tools and pro tips, this guide has everything you need to create soft, touchable mermaid waves that last all day, minus the crunch.

What Are Mermaid Waves, Exactly?

Mermaid waves are loose, flowing bends that fall somewhere between natural beach hair and softly styled curls. They have more definition than bedhead texture but less structure than your classic wave or tonged curl.

Unlike beach waves, which are often messier and more randomly tousled, mermaid waves follow a more uniform S-shape from root to tip. You end up with polished locks without being too sleek, giving you that sun-dried, barely took any time to do my hair look. They also suit nearly every hair type and can be created with or without heat, making them a low-maintenance favourite all summer long.

How To Do Mermaid Waves

Heat-Styling Options

If you’re after long-lasting results with a little more structure, heat styling is the quickest way to go.

  • Use a triple-barrel waver to clamp and ripple your hair from root to end in neat, even sections.
  • Curl hair in alternating directions with a curling wand, then brush through to break up the shape and soften the overall look.
  • Create S-waves with a straightener, gently bending sections back and forth as you glide down the length.

Heatless Overnight Methods

For a more natural, no-heat approach, try styling while you sleep.

  • Braid damp hair into plaits before bed. Two for loose waves, four or more for tighter texture.
  • Use flexible rods or rollers to set hair without heat - great if you want volume at the root.
  • Twist into buns or rope braids and secure gently. Undo in the morning for soft, diffused waves.

FAQs About Mermaid Waves

Q: Can I get mermaid waves if I have short hair?
A: Yes, a triple-barrel waver or small braids can create beautiful texture even on shorter lengths.

Q: What’s the difference between beach waves and mermaid waves?
A: Beach waves tend to be more tousled and random, while mermaid waves are more uniform and softly defined.

Q: Do I need layers to pull off mermaid waves?
A: Layers help add movement, but the style can work on all cuts, especially with the right technique.

Q: Can I use a straightener to create mermaid waves?
A: Absolutely - using the S-shape technique, you can bend your hair back and forth to mimic the wave pattern. This method using straighteners typically tends to create looser and more ‘undone’ mermaid waves.

Q: How do I stop my waves from falling out?
A: Start with a mousse or texturising spray and finish with a flexible hold hairspray to lock in the look without stiffness.
