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

3B forms springy ringlets about marker width, while 3C forms tighter, denser corkscrews about pencil or straw width, with more volume, frizz and shrinkage.

What is the difference between 3C and 4A hair?

3C forms defined corkscrew curls, while 4A forms tighter, more uniform coils that spring up close to the head. 4A also shrinks more and reads as coily rather than curly.

Why does my 3C hair shrink so much?

Tight, dense corkscrews fold the hair's length up onto itself, so dry 3C can look much shorter than it is. Stretching methods like banding help if you want to show length.

What is the best way to moisturize 3C hair?

Layer products on soaking-wet hair using the LOC or LCO method (leave-in, oil and cream), deep condition often, and refresh between washes with water and leave-in.

3C Hair Type

3C hair has tight, springy corkscrew curls about the width of a pencil or straw, densely packed with lots of volume and shrinkage. Here is how to confirm you are 3C, the routine that defines and hydrates, and what to avoid.

Main challenge: Moisture, density and shrinkage

What Is 3C Hair?

3C is the tightest curly type, sitting at the border with coily hair: dense corkscrew curls about the width of a pencil or a drinking straw, packed tightly together for impressive volume. The curls are springy and well defined, but the tight pattern and high density mean 3C is prone to dryness, frizz and noticeable shrinkage, where the dry hair looks shorter than its true length. It is the curliest of the type 3 family, just before the coils of type 4 begin.

How Do You Know You Have 3C Hair?

Match the curl to a pencil or straw. Air-dried 3C forms tight, dense corkscrews with strong volume and visible shrinkage. The border check with 3B: 3B ringlets are looser and wider (marker width), while 3C corkscrews are tighter and more densely packed. The border check with 4A: 4A coils are tighter still and form a more uniform spring close to the head, while 3C is a defined corkscrew curl. Dense, springy, pencil-width corkscrews are the 3C signature.

How Should You Care for 3C Hair?

The 3C routine is moisture-first. The pillars: 1. Cleanse gently with a co-wash or sulfate-free shampoo to preserve natural oils; 2. Deep condition often, since dense curls lose moisture fast; 3. Layer products with the LOC or LCO method (leave-in, then oil and cream in your preferred order) on soaking-wet hair; 4. Define in sections with curl cream and gel, then diffuse on low or air dry; 5. Avoid touching until fully dry, then scrunch out the cast; 6. Protect with a satin bonnet nightly and refresh curls with a water-and-leave-in mix.

What Should 3C Hair Avoid?

3C's density and tightness make dryness and breakage the central risks. Sulfate shampoos, infrequent conditioning and skipping leave-ins all leave the curls dry and frizzy. Brushing dry hair causes breakage and destroys the corkscrews, so detangle only when soaking wet with conditioner. Heat styling without protectant damages the tight pattern, and rough handling or cotton pillowcases cause friction frizz and breakage overnight.
