How to Know Your Hair Type
To know your hair type, wash your hair, apply nothing, and let it air dry to reveal your natural pattern, then match it to a family (1 straight, 2 wavy, 3 curly, 4 coily) and a subtype (a, b or c). Here is the full step-by-step method, plus the signals that separate each type.
What Does Hair Type Mean?
Hair type describes your natural curl pattern, the shape your hair forms on its own without styling. The widely used system sorts hair into four families by pattern, type 1 straight, type 2 wavy, type 3 curly and type 4 coily, and splits each family into three subtypes labeled a, b and c, from the loosest version of the pattern to the tightest. Together these give 12 types from 1A to 4C. Knowing yours is the starting point for a routine that actually fits your hair.
How Do You Find Your Hair Type Step by Step?
Follow four steps.
- Wash your hair and apply no product.
- Let it air dry completely without touching it, since handling and product both hide the true pattern.
- Look at the dried shape to find your family: straight with no bend is type 1, S-shaped waves are type 2, defined loops are type 3, tight coils or zigzags are type
- 4.
- Narrow to the subtype using the family's key signal: strand thickness for type 1, wave strength for type 2, curl width for type 3, and coil shape and shrinkage for type
- That sequence, family first then subtype, is the whole method.
What Is the Most Reliable Hair Type Test?
The air-dry test is the single most reliable check. Because water, product and handling all alter how hair falls, the truest version of your pattern appears when freshly washed hair dries on its own with nothing added and no touching. From there, the defining clue depends on your family: a thickness check for straight hair, a wave-strength check for wavy hair, a curl-width check (against objects like sidewalk chalk, a marker or a pencil) for curly hair, and a coil-shape and shrinkage check for coily hair. The free quiz simply walks you through these signals in order.
Can You Have More Than One Hair Type?
Yes, and it is very common to have two or even three patterns on one head, such as looser curls at the crown and tighter ones underneath. The usual approach is to identify your dominant type, the pattern that makes up most of your hair, and use it to guide your routine, while adjusting care zone by zone where the pattern differs. Mixed patterns are normal, so do not expect every strand to match a single neat label.
Why Does Knowing Your Hair Type Matter?
Because the right routine depends on your pattern. Each type has different needs: straight hair manages oil and flatness, wavy hair builds definition without weight, curly and coily hair prioritize moisture and gentle handling. Knowing your type tells you where to start, and pairing it with your porosity, how your hair handles moisture, completes the picture. Type plus porosity together turn generic advice into a routine built for your actual hair.
Frequently Asked Questions
- How do I know my hair type?
- Wash your hair, apply nothing, and let it air dry. Match the dried shape to a family (1 straight, 2 wavy, 3 curly, 4 coily), then narrow to a subtype. The free quiz does this in two minutes.
- What is the best way to test my hair type?
- The air-dry test is most reliable, because product, water and handling all hide the true pattern. Let clean hair dry untouched, then read the shape it forms.
- Can I have more than one hair type?
- Yes, most people do. It is common to have looser and tighter patterns on different parts of the head. Identify your dominant type and adjust care zone by zone.
- Is hair type the only thing that matters for my routine?
- No. Your porosity, how your hair absorbs and holds moisture, matters just as much. Combining your type and your porosity gives the most useful routine.
