3B Hair: How to Identify, Care For, and Style Your Curls

If your hair forms bouncy ringlets that spring back when you pull them, and looks a lot shorter dry than wet, you probably have 3B hair. It sits in the middle of the Type 3 curls, and most of the work is in keeping those ringlets moisturized, untangled and together.

What is 3B hair?

3B hair forms springy ringlets in a smaller loop than 3A, usually starting near the roots. On our curl type chart, it sits between the wide spirals of 3A and the narrow corkscrews of 3C.

• Bouncy, well-formed ringlets
• Lots of volume, especially as hair dries
• Noticeable shrinkage. Shrinkage is when curls or coils spring up as they dry, so your hair looks much shorter than it really is. It’s normal, and it isn’t damage.
• Tangles and frizz if ringlets get pulled apart

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). Fine 3B hair can need much less product than thick, coarse 3B hair, even with the same curl.

What does 3B hair look like?

Look at a section after it has air-dried without being touched. 3B ringlets are smaller and springier than 3A loops but still open in the middle. They usually keep their shape when wet.

Wet and dry 3B hair can look very different. Wet, the ringlets look longer and looser. As they dry they pull up, and your hair can look several inches shorter. Ringlet size can also vary across your head, with looser curls on top and tighter ones underneath. That’s normal.

Mara Roszak, RŌZ founder and hairstylist, plans for that shrinkage when she cuts curls:

“I cut wet … and set the base shape making sure to account for the ‘spring up’, leaving about an extra 1 inch to two inches of length knowing curls will tighten and appear shorter.”

— Mara Roszak, Hairstylist and Founder of RŌZ

If your curls shrink a lot, tell your stylist before they start cutting.

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

These patterns blend into each other, and plenty of people have two of them. Compare the curls you actually see, not the overall size of your hair. If broad loops sit next to tighter ringlets, you can treat each area a little differently.

How to care for 3B hair

• Wash based on your scalp. Wash when your scalp feels oily or itchy, or when your curls feel coated. Many people with 3B curls wash less often than people with straight hair, but there’s no set schedule.
• Condition every wash, and detangle with it in. Detangling means gently working out knots. Conditioner gives your hair slip, meaning strands slide past each other instead of catching. That’s the moment to work out knots with your fingers, a wide-tooth comb or a brush made for wet hair, starting at the ends.
• Spread products evenly. Work in four or more sections so the hair underneath gets as much product as the top. Patchy product is a common reason some ringlets look defined and others frizz.
• Cut down on friction. Press water out with a lightweight hair towel or soft T-shirt instead of rubbing, don’t leave it wrapped too long, and don’t brush once your hair is dry.
• Don’t assume you need heavy products. 3B curls often need moisture, but how much depends on your strand thickness and how dry your hair feels.
• Get regular trims. RŌZ founder Mara Roszak suggests a cut about every four months, with soft layers so curls don’t get weighed down.

Hairstylist Isabella Sementilli adds a leave-in for clients with drier curls:

“Thick or curly hair tends to be naturally dryer, so adding in a thicker conditioner, even a leave-in conditioner to nourish the curls or thickness for longer during the day.”

How to style 3B hair

These steps cover 3B curls. Our curly hair routine has more detail on each one.

1. Start with freshly washed, conditioned hair that’s still very wet: not dripping, but holding plenty of water.
2. Split your hair into sections. Four is enough for most people; use more if your hair is thick.
3. Smooth a leave-in through each section if your hair feels dry. Milk Hair Serum detangles and calms frizz without feeling heavy.
4. Add your styler: a mousse, gel or cream that helps curls keep their shape as they dry (that’s what “hold” means). Mousse gives softer hold. Gel gives firmer hold and longer-lasting definition. Milk Styling Mousse is made for curls that want smoothing hold without the crunch.
5. Help the curls group together. Gently scrunch, or rake your fingers through and then scrunch, so neighboring curls join into larger ringlets (stylists call this clumping). To scrunch, cup a section in your palm and gently squeeze it upward. For pieces that won’t form, wrap them around a finger, then slide your finger out.
6. Air-dry, or use a diffuser (a cup-shaped blow-dryer attachment that spreads the air out) on low. Don’t touch your hair until it’s completely dry.
7. If it feels stiff, scrunch it gently once dry.

Why start so wet? Angela Soto, a curly hair specialist and owner of Baja Studio NYC, explains:

“If your hair is not frizzy then you can apply damp but most curls are frizzy and you generally want to start pretty wet. The water helps moisturize and lock in shape.”

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

“Damp” means wet but no longer dripping. Most 3B curls frizz once they reach that point, so get your product in before they do.

You can also layer stylers. Hairdresser Nichole Kreps sometimes pairs a cream and mousse:

“Sometimes I’ll air dry with a light cream first and layer a slippery mousse over the top for extra control.”

— Nichole Kreps, Hairdresser, SHED Salon (Oakland) and DEEDA Salon (Sacramento)

If you try this, use small amounts of each. Layering too much is a common cause of buildup.

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

How to refresh 3B curls between washes

You don’t have to refresh every day. If your curls still look fine, leave them alone. When some have frizzed or flattened:

1. Mist only those curls with water.
2. Smooth a small amount of leave-in or mousse over them.
3. Scrunch or finger-coil them back into shape, then let them dry.

Avoid adding a full layer of product each day. It builds up fast. At night, loosely pile your curls on top of your head, or sleep on a silk or satin pillowcase, to cut down on rubbing. Mara Roszak sleeps with her hair down, which she finds keeps her curls best.

Angela Soto, a curly hair specialist and owner of Baja Studio NYC, picks the overnight option by curl and length:

“A silk bonnet is best to reduce frizz from friction on your pillow while sleeping. This is best for hair that loses shape easily. A high loose ponytail with a silk scrunchie is great and easy if you have a tighter curl pattern that doesn’t disrupt so easily when stretched. A bonnet would be best for shorter hair so its not stretched so much and a high pony for longer lengths”

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

A bonnet is a loose cap, usually silk or satin, that covers your hair while you sleep.

Best products for 3B hair

Most 3B routines use three kinds of product. You may not need all of them.

• Rinse-out conditioner. Use every wash. It gives your hair slip for detangling and softens the lengths. If your curls still feel dry, use a mask now and then. It’s a richer conditioner you leave on for a few minutes before rinsing; Foundation Mask is a lightweight, silicone-free option.
• Leave-in conditioner. Stays in to keep hair soft and easier to manage through the day. It’s most useful when your curls feel dry or tangle easily. Milk Hair Serum is our lightweight leave-in that detangles and calms frizz.
• A moisturizing styler. This is what gives curls their shape and hold. Mousse feels lightest and suits fine to medium 3B hair. Cream adds softness and suits thicker or drier curls. Gel gives the firmest hold. Milk Styling Mousse adds hydration along with hold.

How to choose: if your hair is fine, start with mousse alone and add a leave-in only where it feels dry. If it’s thick or dry, start with a leave-in plus a cream or mousse, and add gel if curls won’t last. Our guide to mousse vs. gel goes deeper on hold.
