3A Hair: How to Identify, Care For, and Style Loose Curls

If your hair dries in big, loose loops that wrap all the way around, you probably have 3A hair. It’s the first curl pattern after waves, and like 2C waves, it can lose its shape fast when products are too heavy.

What is 3A hair?

3A hair forms wide, open spirals. Each curl makes a full loop with plenty of space inside it, and you can usually see the pattern from the middle of your hair down, sometimes from the root. On our curl type chart, it’s the loosest of the Type 3 curls.

• Big, round spirals rather than S-shaped waves
• Curls that bounce back when you gently stretch them
• Curls that stretch out or flatten under heavy products
• Frizz, especially in humid weather or if you touch your hair while it dries

Your curl pattern only describes shape. Three other things matter just as much: how thick each strand is (fine, medium or coarse), how much hair you have (density), and how quickly your hair soaks up water and dries (porosity). Two people with 3A curls can need quite different routines because of them.

What does 3A hair look like?

Let your hair dry without brushing it, then look at one section from the side. 3A curls wind into wide loops with plenty of open space in the middle. You’ll see the same shape repeat down the section, not just one curled end.

3A curls can look different from one day to the next. Hair you scrunch and leave alone usually shows rounder curls. Hair you brush, rub with a towel or weigh down with a heavy cream can dry looser and look more like waves.

Many people have more than one pattern. It’s common to see 2C waves on top and 3A curls underneath, or 3A curls around the face and tighter 3B curls at the back. You don’t have to pick one label.

2C vs. 3A hair: what’s the difference?

The difference is shape. 2C hair bends back and forth in deep S-shaped waves. 3A hair turns all the way around itself in a loose spiral.

A few ringlets don’t make your hair 3A. If most sections loop all the way around, you’re closer to 3A. If most bend back and forth, you’re closer to 2C. The line is blurry, and styling can push it either way. Use the label as a starting point, not a rule.

How to care for 3A hair

With loose curls, the goal is enough moisture to keep frizz down without so much weight that the spirals drop.

• Wash based on your scalp and your products. If your scalp feels oily or your curls look limp and coated, it’s time. There’s no set schedule. Leftover styling product weighs loose curls down quickly, and a clarifying shampoo (a stronger shampoo that clears buildup) now and then can help. Follow the label for how often to use it.
• Condition the lengths and detangle while it’s wet. Detangling means gently working out knots. Work conditioner from the middle of your hair to the ends, then gently work it through with your fingers, a wide-tooth comb or a brush made for wet hair before you rinse. Mara Roszak brushes conditioner through her own curls in the shower.
• Use a light leave-in where you need it. A leave-in is a conditioner you don’t rinse out. A small amount of Milk Hair Serum through damp lengths helps detangle and calm frizz without feeling heavy. Keep it off the roots.
• Press, don’t rub. Squeeze water out with a lightweight hair towel or a soft cotton T-shirt, and don’t leave your hair wrapped too long before you add product. Rubbing breaks curls apart and adds frizz.
• Touch it less. Every time you run your fingers through drying curls, you break them up.
• Get regular trims. RŌZ founder Mara Roszak suggests a cut about every four months, with soft layers so curls don’t get weighed down.

Frizz shows up more on curls than on straight hair, and it isn’t always a sign of dryness. Humid air makes hair swell, and beauty product-development expert Lorne Lucree explains why that’s more visible on curls:

“Curly hair can also have more pronounced "frizz" because of that swelling, which is exacerbated visually due to the shape of the fiber, and because curly fibers touch each other at fewer points, so there is less holding them together.”

In other words, curls have fewer places where strands touch and hold each other together. That’s why hold and less touching often fix 3A frizz better than piling on more conditioner.

How to style 3A hair

These steps cover 3A curls. Our full curly hair routine goes into more detail on each one.

1. Start with freshly washed and conditioned hair. Leave it wet, not just damp.
2. If your ends feel dry, smooth a little Milk Hair Serum through the lengths.
3. Add hold, meaning a product that helps curls keep their shape once dry. Work Milk Styling Mousse through your hair one section at a time so every part gets some. It holds through hydration rather than a stiff coating, so curls still move.
4. Scrunch upward to help the curls form: cup the ends in your hands and squeeze them gently toward your scalp.
5. For curls that won’t form, try finger-coiling. Wrap a small piece of hair around one finger, then slide your finger out. Do this only on the pieces that need it, usually around your face.
6. Let it air-dry, or use a diffuser (the cup-shaped attachment for a hair dryer) on low heat. Don’t touch it until it’s completely dry.
7. Once it’s dry, scrunch gently to soften any stiffness.

The curls around your face often need extra attention. Angela Soto, a curly hair specialist and owner of Baja Studio NYC, finds the hairline and the nape (the back of your neck) usually have the tightest, frizziest curls. Her fix for the hairline:

“When styling I’ll advise my client to smooth the hairline with a fine tooth comb after product application and pin with covered clips to set. Once dry you can shake the area out but this helps stretch the area and keep it more defined over the coming days.”

— Angela Soto, Curly Hair Specialist and Owner, Baja Studio NYC

Covered clips are hair clips with a smooth coating, so they hold the hair flat without leaving a crease.

Mousse or gel? Mousse gives lighter, softer hold that suits most 3A curls. Gel holds harder, which can help in humid weather or if your curls drop by midday. Our guide to mousse vs. gel explains when to use each.

Common 3A hair problems (and how to fix them)

Change one thing at a time so you can tell what made the difference.

If your curls feel coated and limp even right after washing, the fix may be simpler than a new routine. Mara Roszak puts it this way:

“Often the answer is a periodic clarifying wash rather than switching the everyday shampoo.”

How to refresh 3A curls between washes

Refresh if your curls have loosened or frizzed but your hair still feels clean. If your scalp feels oily or your hair feels coated, wash instead.

1. Mist only the curls that need it with water until they’re damp.
2. Smooth a small amount of leave-in or mousse over those sections.
3. Scrunch, or finger-coil any loose pieces around your face.
4. Let them dry without touching.

Mara Roszak refreshes her own curls the same way, one spot at a time:

“In the morning, if I need to, I mist just the spots that got flattened or frizzy overnight, then put product back on while it's still damp.”

— Mara Roszak, Hairstylist and Founder of RŌZ

At night, gather your hair loosely on top of your head (sometimes called a “pineapple”) or into a loose braid. The American Academy of Dermatology suggests both to keep curls in shape and cut down on rubbing against the pillow. Or simply sleep with it down: that’s what Mara Roszak does, and she finds it keeps her curls best.

Best products for 3A hair

• A lightweight leave-in. Milk Hair Serum detangles, smooths frizz and moisturizes without feeling heavy.
• Mousse for definition and hold. Milk Styling Mousse is made for curls and waves that want smoothing hold and definition without the crunch.
• Gel, if you need more hold. Useful in humidity or if your curls drop during the day.
• A light finishing oil, used sparingly. A drop of Santa Lucia Styling Oil on dry ends can smooth them. Too much will weigh 3A curls down.
• A clarifying shampoo now and then. A stronger shampoo for when your curls look dull or coated even after washing.

Pick products for your hair rather than your curl type alone. Fine 3A hair may only need mousse. Coarser or color-treated 3A hair may need a leave-in too. Start with one or two products and add another only when you have a specific problem to solve.
