We've always been told that there are only three types of hair textures: straight, wavy, and curly. According to Naturally Curly, however, there are actually four types: straight, wavy, curly, and coily. These four categories are further divided in three sub-categories, with each one being labeled by a letter—A, B, and, C. This IG photo perfectly summarizes every hair type sub-classification.
To better understand the diagram, here's a more detailed visual guide:
Wavy hair has a few bends and the spaces in between each wave (called the S-pattern) differentiate each sub-type.
2A's S-pattern is a few inches part, making it easy to straighten the strands when needed. This type of wavy hair has a tendency to look limp and flat.

2B has a thicker texture compared to 2A, and the S-pattern is more defined. This type of waves has a beachy vibe to it.

The S-pattern of 2C is tighter compared to 2A and 2B, and its texture is more prone to frizz. It's also commonly mistaken as a "curly" hair type.

When the S-pattern looks like a lowercase S or looks more twirly, then the hair is classified as curly. Because curls, in general, are prone to frizz, it's advised to avoid hair care or hairstyling products that contain alcohol and sulfates. The said notorious ingredients are known to dry out the strands.
The large, loose curls create a voluminous look. 3A is coarser in texture than 2C.

3B is a type of curl that reminds us of intertwined DNA links. The S-pattern almost appears like coils and its texture is rougher than 3A's.

3C has springy, tight curls that are prone to dryness and frizz.

Normally seen on people of African descent, the strands are gathered into coils and possess a coarse texture and kinky appearance. The tighter the coils, the more its type progresses in the letter sub-classification. 4A, 4B, 4C hair types need to be conditioned regularly to avoid looking wiry.
