You’ve seen the look on every red carpet since the dawn of the curling iron. It’s that effortless, bouncy, "I just woke up like this" vibe that actually takes about twenty minutes of strategic wrestling with a hot tool. Medium length hair—hitting anywhere from the collarbone to just above the shoulder blades—is the absolute "Goldilocks" zone for this style. It’s long enough to show off a full rotation of a barrel, but short enough that gravity doesn't immediately pull your hard work into a sad, straight line by lunchtime.
Getting big soft curls for medium length hair isn't just about owning a wand. It’s about understanding tension, heat settings, and the physics of hair cooling. Most people mess this up. They hold the iron too long, use too much hairspray too early, and end up looking like a Victorian doll instead of a modern human.
The Secret Physics of the "Soft" Look
Why do some curls look crunchy while others look like silk? It’s basically all about the moisture-to-protein balance in your strands and how you manipulate the hydrogen bonds. When you apply heat, you’re breaking those bonds. When the hair cools, the bonds reform in the shape of the curl. If you drop a hot curl into your palm and let it cool before letting go, it stays. If you let it fall while it's still steaming, the weight of the hair stretches that bond out.
For medium hair, the weight is your friend. You don't want the tight "S" shape of a prom style from 2004. You want a "C" shape.
Equipment Matters More Than You Think
Don’t buy a 1/2 inch iron. Just don't. For big soft curls for medium length hair, you need a barrel that is at least 1.25 inches or 1.5 inches. Anything smaller creates a spiral. Anything larger on medium hair won't have enough surface area to actually wrap the hair around, and you’ll just end up with a slight bend at the ends.
- Ceramic barrels are great for fine hair because they distribute heat evenly and are gentler.
- Titanium barrels get hotter and stay hotter, which is necessary for thick, coarse hair that usually refuses to hold a style.
- The T3 Micro or Dyson Airwrap are the industry standards for a reason, but honestly, a basic $30 Conair will work if your technique is solid.
Honestly, the biggest mistake is the "clamp." If you use the clamp of a traditional curling iron and roll from the bottom up, you’re frying your oldest, most damaged ends while the roots stay flat.
Instead, use it like a wand. Hold the iron vertically. Wrap the hair around the barrel, starting near the scalp, and leave the last inch of your hair out. This creates that "lived-in" look that doesn't feel too precious or overdone.
Real-World Examples: The Celeb Blueprint
Look at someone like Alexa Chung or Margot Robbie when she had her mid-length lob. Their stylists aren't going for perfection. They’re going for movement. Jen Atkin, the stylist behind the Kardashians' hair, often talks about "the shake." Once the curls are done, she doesn't leave them. She literally has the client flip their head upside down and shakes the roots out.
If you leave the curls in their "perfect" tubes, you look like you’re trying too hard. The goal of big soft curls for medium length hair is to make people wonder if your hair just naturally dries in beautiful, voluminous waves. It doesn't. We know it doesn't. But we can pretend.
Heat Protection is Not Optional
There is a study by the Journal of Cosmetic Science that shows heat over 350 degrees Fahrenheit causes irreversible damage to the hair cuticle. If you see steam rising from your hair, that's not just product evaporating—that's the internal moisture of your hair boiling. Use a heat protectant. Something with silicones like dimethicone or light oils like argan oil. It creates a physical barrier.

The Step-by-Step Breakdown (The Non-Robotic Version)
First, prep. Start with dry hair. Trying to curl damp hair is a recipe for "bubble hair," which is exactly what it sounds like—the water turns to steam inside the hair shaft and explodes the cuticle.
Sectioning is next. Don't be lazy. Use clips. Divide your hair into a bottom, middle, and top layer. If you try to grab random chunks, you’ll miss the back, and you’ll have that "mullet effect" where the front is curly and the back is a flat mess.
- The Direction Flip: Always curl away from your face. On the right side, wrap clockwise. On the left side, wrap counter-clockwise. This opens up your features.
- The "Flat Wrap" vs. The "Twist Wrap": For big soft curls, keep the hair flat against the barrel like a ribbon. Don't let it twist like a rope. A flat wrap gives you more volume and a wider wave.
- The Cool Down: This is the most important part. Do not touch your hair for at least five minutes after you finish. Let it get cold. If you brush it out while it's warm, the curls will disappear.
- The Breakup: Use a wide-tooth comb or just your fingers. Avoid a fine-tooth comb unless you want a 1920s finger wave (which is cool, but not what we're doing here).
Why Medium Length is the "Sweet Spot"
If your hair is too long, the curls get heavy and look "stringy." If it's too short, you look like a mushroom. Medium length—specifically that range from the chin to the collarbone—allows the curl to sit right around your jawline. This draws the eye upward and acts like a natural facelift.
You’ve probably noticed that stylists often use "sea salt spray" after curling. Be careful with that. Salt is a desiccant. It sucks moisture out. If your hair is already dry or bleached, sea salt spray will make your big soft curls for medium length hair look like straw. Instead, use a "dry texture spray." It gives the grip and volume without the sandpaper feel. Oribe Dry Texturizing Spray is the holy grail here, but the Kristin Ess version at Target is a solid dupe.
Common Obstacles and How to Fix Them
"My hair is too straight and won't hold a curl."
The problem is likely your conditioner. If you use a heavy, buttery mask before curling, your hair is too "slippery" to hold a shape. Use a volumizing shampoo and skip the heavy conditioner on the day you want curls. Use a mouse on damp hair before blow-drying to give the hair "teeth."
"My curls look like 'Goldilocks' and I hate it."
You're curling too close to the root. Start the wrap about two inches down from your scalp. And for the love of all things holy, leave those ends straight. That straight one-inch at the bottom is what makes it look modern.
"The back of my head is a disaster."
Use two mirrors. Or, better yet, bring all your hair forward over your shoulders as you curl. Once you finish a section, toss it back. It’s okay if the back isn't as perfect as the front; human hair isn't supposed to be perfectly symmetrical.
The Role of Hair Density
Fine hair needs more product (mousse, hairspray) but less heat. Thick hair needs more heat but fewer products that might weigh it down. If you have a lot of hair, you might need to take smaller sections. If you take a section that is too thick, the heat won't reach the middle of the "ribbon," and the curl will fall out in ten minutes.

Actionable Next Steps
To get started with big soft curls for medium length hair, don't just jump in with a hot iron today.
- Audit your tools: Check the diameter of your iron. If it’s 1 inch or smaller, save it for tighter styles. Target a 1.25-inch barrel for that soft look.
- The "Dirty" Trick: Try curling on "second-day" hair. The natural oils from your scalp give the hair more grip than freshly washed, "squeaky" hair.
- Practice the "Finger Coil": Before you even use heat, practice the motion of wrapping a section of hair away from your face.
- Invest in a Texture Spray: Buy a bottle of dry texture spray. It is the single most important product for turning "prom curls" into "cool-girl waves."
- Let it Set: Next time you curl, pin each loop to your head with a metal clip while it cools. This "pin curl" method ensures the style lasts for 48 hours instead of four.
