What is the difference between 3A and 3B hair?

Curl width and volume. 3A curls are large and loose, about sidewalk-chalk width, while 3B curls are tighter, springier ringlets about marker width, with more volume and frizz.

What is the difference between 3B and 3C hair?

3B forms springy ringlets about marker width, while 3C forms tighter corkscrews about pencil or straw width, packed more densely with more shrinkage.

Why is my 3B hair so dry?

The tighter ringlet pattern stops scalp oils from traveling down the strand, so 3B trends dry by nature. Co-washing, deep conditioning and leave-ins keep it hydrated.

How do I define my 3B curls?

Apply curl cream and gel to soaking-wet hair, form clumps with praying-hands and scrunching, diffuse or air dry without touching, then scrunch out the cast once dry.

3B Hair Type

3B hair has springy, well-defined ringlets about the width of a marker, with lots of volume and a tendency to frizz and dryness. Here is how to confirm you are 3B, the routine that defines and hydrates curls, and what to avoid.

What Is 3B Hair?

3B is the middle curly type: bouncy, springy ringlets about the diameter of a marker, tighter and more voluminous than the loose curls of 3A. The curls are well defined and full, giving 3B its signature volume, but the tighter pattern means scalp oils struggle to travel down the strand, so 3B trends dry and frizz-prone. It is a true curl, packed more densely than 3A, with a strong, lively spring when healthy.

How Do You Know You Have 3B Hair?

Match the curl to a marker. Air-dried 3B curls form springy ringlets about marker width, with clear volume and bounce. The border check with 3A: 3A curls are larger and looser (sidewalk-chalk width) and can pull nearly straight, while 3B curls are tighter and springier. The border check with 3C: 3C corkscrews are tighter still (pencil width) and denser. Voluminous, springy, marker-width ringlets are the 3B signature.

How Should You Care for 3B Hair?

The 3B routine hydrates and defines. The pillars: 1. Cleanse with a sulfate-free shampoo or co-wash to protect moisture; 2. Deep condition regularly, since 3B trends dry; 3. Apply a curl cream plus a gel to soaking-wet hair, using praying-hands and scrunching to form clumps; 4. Diffuse on low or air dry without touching; 5. Scrunch out the cast once fully dry for soft, defined ringlets; 6. Protect curls at night with a satin bonnet or pillowcase, and refresh with water and leave-in between washes.

What Should 3B Hair Avoid?

Dryness and disruption are 3B's main enemies. Sulfate shampoos and skipped deep conditioning leave the curls parched and frizzy. Brushing dry curls shatters the ringlets into a frizzy cloud, so detangle only with conditioner in. Touching curls as they dry breaks the clumps. And while 3B needs richer products than wavy hair, piling on too much heavy butter can still weigh the springy ringlets down, so find the balance.
