How to Curl Your Hair for Big, Soft Beach Waves (Short to Medium Hair)

Introduction

Big, soft beach waves look effortless, but most of us learned the hard way that a curling iron and good intentions aren’t enough on their own — especially with short to medium length hair, where curls tend to fall flat or look too tight and springy instead of loose and undone. This tutorial breaks down the technique that actually gets you those soft, Victoria’s Secret–style waves, without a trip to the salon.

Why Short to Medium Hair Needs a Different Approach

Beach wave tutorials often assume you’re working with long hair, but shorter lengths behave differently — curls set faster, waves can look tighter than intended, and volume tends to sit closer to the roots. The fix isn’t a different tool, it’s adjusting your section size, curl direction, and how you brush the curls out afterward.

Choosing the Right Curling Iron

Barrel size matters more than almost any other factor for short to medium hair. A curling iron with a 1-inch barrel is the sweet spot for most lengths in this range — smaller barrels (under an inch) tend to create tight, spiral curls that read more “costume” than “undone beach wave,” while larger barrels (over 1.25 inches) often can’t grip shorter hair long enough to hold a curl at all. If your hair sits above your shoulders, staying at or under 1 inch will give you the most control.

What You’ll Need

A curling iron (1-inch barrel works well for most short-to-medium lengths)
Heat protectant or thermal spray
A volumizing or texturizing hairspray
A detangling brush for prep
A boar bristle or paddle brush for brushing out curls
Hair clips for sectioning

Step-by-Step Tutorial

1. Detangle Before You Start

Run a detangling brush through your hair from ends to roots before you apply any heat. Curling over tangled or knotted hair leads to uneven sections and can cause the iron to catch and pull, which is both uncomfortable and damaging.

2. Prep with Heat Protectant

Always start with a heat protectant spray on dry hair before you pick up the curling iron. This isn’t optional if you want to avoid damage and keep your ends from looking fried.

3. Section Your Hair

Divide your hair into two to four sections depending on thickness, clipping the top layers out of the way. Working in smaller sections gives you more even, consistent curls than trying to curl large chunks at once.

4. Alternate Curl Direction

For the most natural, undone look, alternate the direction of each curl — some pieces wrapped away from your face, others toward it. Curling every piece in the exact same direction is what makes waves look too uniform and “done.”

5. Wrap, Don’t Clamp

Wrap sections around the barrel rather than clamping them straight down the length. This creates a softer S-shaped wave instead of a tight, ringlet curl, which reads much closer to a natural beach wave.

6. Let Curls Cool Before Brushing

This is the step people skip most often, and it makes a huge difference. Let each curl cool completely — ideally by pinning it up against your head — before brushing it out. Brushing while it’s still hot loosens the wave pattern almost immediately.

7. Brush and Shake Out

Once everything has cooled, gently brush through the curls with a paddle or boar bristle brush to soften them into loose waves, then shake your hair out with your fingers for extra volume and texture.

8. Lock It In

Finish with a light mist of the Chi Magnified Volume Hair Spray + Thermal Spray, focusing on the roots for lift and the ends for texture and hold. It works well here specifically because it’s formulated to double as a heat-styling spray, so it adds hold without weighing down the wave you just created.

Troubleshooting Common Problems

My curls fall flat within an hour. Check three things in order: whether you let each curl fully cool before brushing, whether you’re using enough hairspray, and whether your hair was completely dry (not just towel-dry) before you started. Any one of these can cut hold time dramatically.

The waves look tight and springy instead of soft. This usually means your barrel is too small for the look you want, or your sections were too thin. Take slightly larger sections and make sure you’re wrapping (not clamping) around the barrel.

One side curls better than the other. This is normal — most people have a dominant hand and naturally curl more consistently on one side. Slow down and pay extra attention to your non-dominant side, or curl it first while your technique is freshest.

My hair won’t hold curl at all. Freshly washed, very slippery, or silicone-heavy product buildup can all prevent hair from gripping the barrel. Try curling on day-old hair with a light dusting of dry shampoo at the roots, which gives the iron more grip.

Common Mistakes to Avoid

Using sections that are too large — this leads to uneven, half-curled pieces.
Skipping the cool-down step — curling looks perfect right off the iron and falls flat within the hour.
Curling every piece the same direction — this is what makes waves look artificial instead of undone.
Too much product before curling — heavy styling product can weigh curls down and shorten how long they hold.
Skipping the detangling step — curling over knots leads to uneven sections and unnecessary breakage.

How Long Should This Actually Take?

Once you’ve got the technique down, a full head of short to medium hair typically takes 15 to 25 minutes, including sectioning. Your first few attempts will likely take longer while you’re still building muscle memory for the wrap-and-hold motion — that’s normal, and it speeds up quickly with practice.

Pro Tips

Curl away from your face on the front pieces for a more flattering, face-framing effect.
Use a smaller barrel on shorter layers so they hold curl as well as your longer pieces.
Dry shampoo the day after to refresh waves and add texture without restyling from scratch.
Sleep in a loose braid the night before to extend how long your waves last.
Don’t rush the wrap — a slow, deliberate wrap around the barrel holds far better than a quick one.

Frequently Asked Questions

How do I make my waves last through a workout or humid weather? A stronger-hold, humidity-resistant hairspray applied while curls are still slightly warm helps significantly. Braiding hair loosely before high-humidity activities and re-shaking it out afterward can also extend hold.

Can I use this technique on layered hair? Yes, and layers actually pick up waves quickly since shorter pieces curl faster. Just be mindful of section size on your shortest layers so they don’t over-curl relative to the rest of your hair.

Is it bad to curl my hair every day? Daily heat styling does add up in terms of damage over time, regardless of technique. Using a proper heat protectant every time and giving your hair the occasional heat-free day helps offset this.

Conclusion

Soft beach waves on short to medium hair come down to three things: smaller sections, alternating curl direction, and letting each curl cool before you touch it. Once that becomes muscle memory, this whole routine takes just a few minutes. Watch the full tutorial above to see the technique step by step, and give your waves a day or two of practice before you judge the results — like any styling skill, it gets faster and more natural every time. ✨
