Type 4 hair is the category of very tightly curled, coily or “kinky” hair in the curl-typing system, known for tight coils, high shrinkage, and a strong need for moisture and gentle care.

Quick Scoop: What’s Type 4 Hair?

  • Type 4 = coily/kinky hair with the tightest curls of all hair types.
  • Strands grow more “up and out” (afro shape) than straight down.
  • Common traits: tight curls or zig‑zag patterns, lots of shrinkage, and big volume.
  • It’s naturally drier and more fragile because scalp oils struggle to travel down the bends in the hair.

In simple terms: if your curls form tiny coils or zig‑zags, shrink a lot when dry, and feel dry without product, you’re probably in the type 4 family.

The Subtypes: 4A, 4B, 4C

Type 4 hair is usually split into three sub‑types.

  • 4A hair
    • Has clearly defined, springy coils (think small, visible ringlets).
* Usually holds definition more easily and can retain moisture a bit better than 4B/4C, but still gets dry without care.
  • 4B hair
    • Curls are less defined and bend in an “S” or “Z” shape, often looking fluffy or cotton‑like.
* Has significant shrinkage and tangles easily, so it needs extra gentle detangling and regular moisture.
  • 4C hair
    • Has the tightest coils and often looks more like a soft cloud of texture than defined curls unless styled.
* Can experience extreme shrinkage (often over 70%) and is very delicate, so protective styles and moisture are key.

How to Tell if You Have Type 4 Hair

Ask yourself a few quick questions based on what experts describe:

  1. Do your curls form very tight coils or zig‑zags rather than big waves or loose spirals?
  2. Does your hair look way shorter dry than it does when fully stretched or wet (heavy shrinkage)?
  3. Does your hair tend to feel dry quickly, even after you add product, unless you really focus on moisture?
  4. Does your hair create lots of volume and stand out rather than lying flat?

If you’re saying “yes” to most of these, you’re likely somewhere in the 4A–4C range.

Basic Care Tips (Super Short Version)

Because type 4 hair is delicate and prone to dryness, most guides recommend:

  • Regular deep conditioning and leave‑in conditioner.
  • Using oils/butters to seal in moisture, not to replace it.
  • Gentle detangling (fingers or wide‑tooth comb) on wet or very damp, conditioned hair.
  • Protective or low‑manipulation styles (twists, braids, etc.) to reduce breakage.
