The hair typing system can be a source of confusion for many people, especially those with kinky or coily hair. Two of the most commonly confused hair types are 4B and 4C.
While these two textures may look similar at first glance, when we compare 4B vs. 4C hair, there are some glaring differences between the two that can dramatically impact your styling and haircare routine.
So if you’re wondering what those differences are and what they mean for your hair, just read on! Today, we'll take a closer look at 4B and 4C hair and how they compare to each other. Let’s jump right in!

What Is 4B Hair?
Type 4B hair is one of the most common hair textures for black women. The name 4B comes from the Andre Walker Hair Typing System, which is a classification designed to categorize each hair type based on its texture and curl pattern.
This system assigns a number to each hair type, with 1 representing straight hair, 2 for wavy hair, 3 for curly hair, and 4 for kinky or coily hair. Next, each hair type is further divided into subcategories that are identified by letters A, B, and C.
Subtype A indicates a looser curl pattern, B represents a tighter curl pattern, and C denotes the tightest curls. 4B hair is characterized by tight, "Z"-shaped coils that have a less defined curl pattern than type 4A hair.
While type 4B hair can be highly voluminous and have a lot of shrinkage, it also tends to be fragile and prone to breakage due to its tightly coiled nature. Type 4B hair is also highly susceptible to dryness, as the natural oils produced by the scalp have a difficult time traveling down the hair shaft.
What Is 4C Hair?
Like 4B hair, 4C hair is a hair type listed under the Andre Walker Hair Typing System. Type 4C hair is a hair type that is mainly characterized by its tightly coiled curls.
It is considered the most fragile and delicate hair type, with tight coils that form small or barely defined ringlets. 4C strands are tightly coiled, although they lack a cohesive curl pattern when dry.
However, it’s not uncommon to see “Z” and “S” shaped curls, particularly when the hair is wet. Because of its tightly coiled texture, type 4C hair has a low natural sheen and may feel rough or wiry to the touch.
4C hair can be any density, but typically, the strands are densely packed together. Due to those characteristics, 4C hair is often regarded as the most fragile and dryness-prone hair type.
What Is the Difference Between 4B and 4C Hair?
With so many similarities, it’s easy to get 4B and 4C hair confused with each other. Nonetheless, each hair type has unique needs. So in this section, we’ll break down some of the major differences between types 4B and 4C hair.
| Characteristics | 4B Hair Type | 4C Hair Type |
| Curl Pattern | Tight, "Z"-shaped coils | Tightly coiled curls |
| Curl Definition | More defined | Less defined |
| Shrinkage | Moderate | Very high, up to 90%+ |
| Fragility | Less fragile | More fragile, brittle |
| Dryness | Moderate | More prone |
| Oil Distribution/Spread | Difficult, but better | Most difficult, weakest |
| Moisture Retention | Better overall | Less overall |
4B vs. 4C Hair Types: Differences and Characteristics
- They have different curl patterns - 4B kinks and coils have considerably more definition than 4C strands. 4C hair, by comparison, is composed of tighter coils overall, but they appear less defined.
- 4C has more shrinkage - While both 4B and 4C hair have shrinkage, type 4C typically has the most out of all the hair types. It can shrink to as little as 10 percent of its total length! That means that even if your hair is 20 inches long, it can appear as little as 2 inches in its naturally shrunken state.
- 4C hair is weaker and more brittle - Due to 4C hair’s tightly coiled structure, your natural scalp oils have a hard time traveling down your strands. As a result, it’s much more fragile than 4B hair.
- 4B hair typically has better moisture retention - Because 4B and 4C hair are kinky or coily, both can have issues with moisture retention. However, 4C hair is typically drier than 4B and requires more topical hydration.
Note: Most, if not all, of us, have more than one hair texture. So, it's possible that you have both 4B and 4C hair. In that case, you'd need to cater to both hair types.
