What is the difference between 2A and 2B hair?

2A waves are loose, beachy and start near the ends, while 2B waves are defined, start around mid-length, hold better and come with a frizz-prone crown.

What is the difference between 2B and 2C hair?

2B is mostly defined waves, while 2C waves more strongly from the root and mixes in actual curls. If you see real spirals among the waves, you are closer to 2C.

How do I stop my 2B crown from going flat and frizzy?

Clip the roots for volume while drying, apply a light gel to soaking-wet hair, and avoid touching the crown as it dries. A microfiber towel instead of a rough one also cuts frizz.

Should 2B hair use gel?

Yes, a light gel applied to soaking-wet hair is one of the best ways to define 2B waves. Scrunch out the cast once dry for soft, frizz-free definition.

2B Hair Type

2B hair has defined S-shaped waves that start around mid-length, with more body than 2A and a frizz-prone crown. Here is how to confirm you are 2B, the routine that defines waves and controls frizz, and what to avoid.

2B at a glance

Pattern: Defined S-waves from mid-length
Reference: Medium strands
Frizz: Moderate, mostly at the crown
Oiliness: Moderate
Main challenge: Defining waves while taming frizz

What Is 2B Hair?

2B is the middle wavy type: clear, defined S-shaped waves that begin around mid-length and hold their shape better than the loose waves of 2A. The strands are usually medium, and the crown tends to sit flatter and frizzier than the lengths, which is the classic 2B complaint. The waves are consistent enough to style with curly-hair techniques, but loose enough that the hair still straightens with reasonable effort, placing 2B firmly in the middle of the wavy family.

How Do You Know You Have 2B Hair?

Look for defined waves plus a frizzy crown. Air-dried 2B hair forms a clear S-wave from around mid-length, with a flatter, sometimes frizzy top section. The strands feel medium. The border check with 2A: 2B waves are more defined, start higher and hold better. The border check with 2C: 2B is still mostly wave, while 2C mixes in actual curls and waves more strongly from the root. Defined mid-length waves with a frizz-prone crown is the 2B signature.

How Should You Care for 2B Hair?

The 2B routine defines the wave and calms the crown. The pillars: 1. Wash with a sulfate-free shampoo and a light conditioner, detangling in the shower; 2. Apply a light gel or wave-enhancing cream to soaking-wet hair; 3. Scrunch upward and consider clipping the roots for crown volume to fight the flat top; 4. Air dry or diffuse on low without disturbing the waves; 5. Once dry, scrunch out any gel cast for soft, defined waves; 6. Use a microfiber towel or T-shirt to dry, never a rough towel, which causes frizz.

What Should 2B Hair Avoid?

2B lives or dies by frizz control and product weight. Heavy creams and oils drag the waves loose and flat, while too little product leaves the crown frizzy and undefined, so aim for light but present hold. Rough towel-drying and brushing dry both shatter the waves into frizz. And washing too often strips the moisture the waves need to stay defined, so space out washes and refresh between them.
