What is 4A Hair?

What is 4A Hair

4A hair features tight, springy S-shaped curls that range from the width of a crochet needle to a toothpick. It typically experiences less shrinkage than 4B and 4C hair, though texture and curl patterns can vary even on the same head.

While both 4A and 4B are coily hair types, they differ in several ways:

  • Curl Pattern: 4A hair forms defined S-shaped curls, while 4B hair has a tighter Z-shaped pattern.
  • Texture: 4A curls are more defined, whereas 4B hair is fluffier and less defined.
  • Shrinkage & Breakage: Both hair types need plenty of moisture, but 4B hair experiences more shrinkage and is generally more prone to breakage.

Although 3C and 4A hair types are closely related, they have distinct characteristics.

  • Curl Pattern: 3C hair has larger, corkscrew curls, while 4A hair features tighter, springy S-shaped coils.
  • Texture: 3C hair is typically denser, whereas 4A hair has more defined coils.
  • Moisture Needs: Both hair types are prone to dryness, but 4A hair usually dries faster and requires more frequent moisturizing and deep conditioning.

How to Identify Your Curl Type

Understanding your curl type helps you choose the right products and routine.

  • Examine your curls when wet and after they dry.
  • Identify whether your pattern is wavy, curly, or coily.
  • For Type 4 hair, tighter curls indicate a higher subtype (4A, 4B, then 4C).
