The biggest lie in the beauty world is that "effortless" hair is actually effortless. We’ve all seen it on Instagram—that perfect, salt-crusted, wind-blown texture that looks like someone just stepped off a surfboard in Malibu. But if you've ever picked up a curling iron and ended up looking more like a colonial judge or a pageant queen from 1994, you know the struggle is very real. Learning how to curl beach waves isn't actually about the curl itself; it's about the "undone" finish.
Most people fail because they treat beach waves like traditional ringlets. They hold the iron too long. They curl all the way to the ends. They use the wrong heat. Stop doing that.
The secret to modern hair isn't perfection. It’s tension and direction. If you want that lived-in look, you have to embrace a little bit of chaos. Honestly, your hair should look slightly "messy" before you even leave the house, because as soon as you hit the humidity or the wind, it’s going to drop anyway.

The Gear You Actually Need (And What to Skip)
Don't buy a 2-inch barrel. Just don't. While it looks like it would create big, breezy waves, it usually just creates a slight bend that falls out in twenty minutes. Most professional stylists—think Chris Appleton or Jen Atkin—typically reach for a 1-inch or a 1.25-inch barrel. The smaller barrel provides the "spring" needed to keep the style alive, while your technique (pulling the hair straight while it’s hot) creates the wave.
- The Iron: A ceramic or tourmaline wand or clip iron. If you use a clip iron, you aren't actually going to use the clip the way your mom did.
- Heat Protectant: This is non-negotiable. Using a product like the Oribe Royal Blowout or even a drugstore classic like Tresemmé Thermal Creations prevents that fried, "crunchy" look.
- Dry Texture Spray: This is the MVP. Forget hairspray that freezes hair in place. You want something like Kristin Ess Dry Finish Working Texture Spray to add grit.
Why How to Curl Beach Waves Starts with the Prep
If your hair is squeaky clean, it’s going to be slippery. Slippery hair doesn't hold a wave. Ideally, you’re doing this on day-two hair. If you just washed it, you need to "dirty" it up. Apply a volumizing mousse to damp hair and blow-dry it roughly with your hands. No round brush. We want volume and a bit of rough texture.
Sectioning is where most people get bored and quit. You don't need forty clips. Just split it down the middle and then horizontally. Focus on the bottom layer first. It doesn't have to be perfect because nobody sees the bottom layer anyway—it just provides the "shelf" for the top layers to sit on.
The Technique That Changes Everything
Here is the part everyone gets wrong: the ends. When you are figuring out how to curl beach waves, the most important rule is to leave the last two inches of your hair completely straight.
Grab a one-inch section of hair. Hold your curling iron vertically, with the cord pointing toward the ceiling. Wrap the hair away from your face. This is crucial. If you curl toward your face, you’ll look closed off. Curling away opens up your features.
As you wrap, don't overlap the hair on the barrel. Wrap it like a candy cane stripe. Hold for maybe five seconds. When you let go, don't let the curl bounce into your hand. Instead, pull the tail of the hair down firmly while it's still hot. This "stretches" the curl into a wave.
Switch Directions for Realism
Natural hair doesn't all move in one direction. While the pieces framing your face must go backward, you should alternate directions for the rest of your head. One section away from the face, the next section toward it. This prevents the waves from clumping together into one giant "mega-curl" throughout the day.
Dealing With Different Hair Lengths
Short hair is tricky. If you have a bob or a lob, you have less "runway" to work with. If you curl too much, you’ll end up with a triangle shape. Focus the wave strictly on the mid-shaft of the hair. Leave the roots flat and the ends straight.
For long hair, the weight of the hair is your enemy. You might feel tempted to use a higher heat setting, but that just causes damage. Instead, use smaller sections. It takes longer, but the heat penetrates the hair more evenly.
The Cool-Down Phase
Never, ever touch your hair while it’s hot. This is the hardest part. You'll want to brush it out immediately because the curls look too tight. Resist. Let your hair look like Shirley Temple for ten minutes while you do your makeup or drink coffee.
Once the hair is completely cool to the touch, flip your head upside down. Shake your roots with your fingertips. Use a wide-tooth comb—never a fine-brush—to break up the sections. This is when the magic happens. The tight ringlets transform into those beachy, "I just woke up like this" undulations.
Fixing Common Mistakes
If your waves look too "done," you probably curled too close to the root. Start the curl at eye level. This keeps the top of your head sleek and prevents that 1980s volume that doesn't really fit the beachy aesthetic.
If your waves fall out in an hour, your hair might be too heavy or too healthy. Healthy hair is smooth, and smooth hair doesn't have "grip." Increase your use of sea salt spray. Bumble and bumble Surf Spray is the industry standard for a reason. It adds that slight salt-water stiffness that mimics a day at the ocean.

Advanced Pro Move: The Flat Iron Wave
Some people find a curling iron too clunky. You can actually achieve how to curl beach waves using a flat iron. It’s a "push-pull" motion. You pinch the hair and create an "S" shape, tapping the flat iron over the curves to set them. It creates a much flatter, more modern wave that is very popular in editorial photography. It’s harder to learn, but the results are arguably more "authentic" looking.
Finishing Touches
Finish with a shot of cool air from your hair dryer if you have one. Then, take a tiny bit of hair oil—just a drop—and run it through the very ends. This prevents the straight ends from looking dry or frayed. You want them to look intentional, not like an afterthought.
- Stop using the clamp if you want a modern look; just wrap the hair over the top.
- Leave 1-2 inches of the ends out of the heat entirely.
- Alternate the direction of your curls to prevent the "unified wave" look.
- Wait for the hair to be cold before you even think about touching it.
- Use a texture spray instead of a firm-hold hairspray.
The reality of beach waves is that they look better as the day goes on. By hour four, when some of the bounce has dropped and your natural oils have started to mix with the product, the hair looks its best. Don't overthink the symmetry. If one side is a little bit different than the other, let it be. Perfection is the enemy of the beach wave.
To maintain the look for "day three" hair, don't re-curl the whole head. Just pick three or four pieces on the very top layer and the ones framing your face. Refresh those, add a bit more dry shampoo to the roots, and you're good to go. This saves your hair from excessive heat damage while keeping the style looking fresh. This approach works because it builds on the existing texture rather than trying to reset it every single morning.
