How to Use a Curling Iron to Create Wavy Hair | Beach Waves Steps

The difference between tight curls and loose, natural waves comes down to a few specific choices: how you hold the iron, how long you hold each section, and whether you leave the ends out. Whether you’re aiming for soft beachy texture or more defined waves for an event, the technique below follows the same core sequence used by the pros at Aveda, Cloud Nine, and ShunSalon.

Start With Dry Hair and Heat Protection

Heat styling on wet or damp hair is the fastest way to damage strands and get uneven results. The cuticle is still swollen with water, so the iron essentially boils the moisture inside the hair. Always blow-dry completely before you pick up the iron.

Before heat touches your hair, apply a heat protectant spray or cream evenly from mid-length to ends. This is the single most important step to avoid split ends and breakage over time.

Now you’re ready to section the hair. Clip up the top half and work from the bottom up so every strand gets styled once, with nothing missed. Cloud Nine’s guide notes that working in larger sections produces fuller, more voluminous waves, while smaller sections create tighter texture. For beachy waves, ShunSalon recommends a 1-inch barrel and 1–2 inch sections.

How to Wrap, Hold, and Release Each Section

This is where the wave—rather than a tight curl—actually happens. The key moves:

• Hold the iron vertical, with the clamp closed, per Aveda’s tutorial.
• Wrap the hair around the barrel, leaving about 1–1.5 inches of the ends out. Ends left out create the relaxed, modern wave instead of a uniform ringlet.
• Catch the curl in your palm for a few seconds before letting it hang. This sets the wave while the hair is still warm.
• Alternate the wrapping direction—twist one section away from your face, the next one toward your face. This is what gives the final result that natural, mixed-direction beach texture instead of uniform corkscrew curls.

Work your way up the head in horizontal layers. After all sections are done, run fingers through the waves or gently brush with a wide-tooth comb to break them apart and soften the look.

When you’re comparing tools, the barrel size matters for your result. If you’re shopping for a new iron, our tested picks for the best curling iron for wavy hair cover which barrels suit different hair lengths and textures.

What to Do After Styling

Once every section has been curled, cooled, and loosened, finish with a light-hold hairspray to keep the waves in place without making them stiff or crunchy.

Touch the curls as little as possible while they cool. Handling warm curls pulls out the bend and leaves you with a straighter, flatter result than you wanted.

7 Common Mistakes That Ruin the Wave

Most poor results trace back to one of these seven habits. Skipping any of these will set you back:

• Curling wet or damp hair. Dry hair only, as noted above.
• Skipping heat protectant. Heat damage builds up invisibly at first, then shows as frizz and split ends.
• Handling hair before it cools. Let each curl sit in your palm for a few seconds, then let it hang.
• Curling every section in the same direction. Alternate for natural-looking waves, per ShunSalon and Aveda.
• Not leaving the ends out. Leave 1–1.5 inches out for a beachy finish.
• Using a barrel that’s too small. A 1-inch barrel is the sweet spot for waves; smaller barrels produce tighter curls.
• Brushing out waves too aggressively. A wide-tooth comb preserves the wave pattern better than a dense brush.

Getting great waves on the first try takes practice with the timing and the direction alternation.
