What Is Your Hair Type? A Simple Way to Find Your Curl Pattern

If you've ever stood in front of a wall of hair products feeling totally lost, knowing your hair type is the shortcut that makes everything else click. The hair type system sorts hair into four big families based on the shape of the strand: how straight, wavy, curly, or coily it grows. Once you know roughly where you land, choosing products and styling routines gets a lot less like guesswork. Here's the simple way I think about it, so you can figure out your own pattern at home.

The 4 Hair Types (and Their a/b/c Subtypes)

The most popular system breaks hair into four numbered types, each with three subtypes (a, b, c) that describe how loose or tight the pattern gets. You don't have to be perfect about this. Most people are a blend, and your hair can even differ from the crown to the nape.

• Type 1 — Straight: No natural curl. 1a is fine and flat, 1b has more body, 1c is coarse and can hold a slight bend.
• Type 2 — Wavy: A loose S-shape. 2a is barely-there waves, 2b is more defined, 2c is thick waves that start near the root.
• Type 3 — Curly: Clear, springy curls. 3a is loose and large like sidewalk chalk, 3b is springier like a marker, 3c is tight corkscrews like a pencil.
• Type 4 — Coily: Tight coils or zig-zags. 4a forms a defined coil, 4b bends in sharp Z angles, 4c is the tightest with little visible definition.

A handy trick for types 3 and 4: compare a curl to a common object. If it wraps around a pencil, you're likely 3c; a chunky marker leans 3b; a thick highlighter leans 3a.

How to Identify Your Curl Pattern at Home

The biggest mistake here is judging your hair when it's wet, brushed, or product-loaded. Curl pattern shows up best when hair dries on its own with nothing fighting it. Try this:

• Wash and let it air-dry. Use a gentle cleanser, don't brush it out, and let your hair dry naturally without scrunching or diffusing. The shape it falls into is your true pattern.
• Look at a single clean strand. Pull one strand and lay it flat. Straight stays straight, an S-bend means wavy, a spiral means curly, and a tight zig-zag means coily.
• Check different sections. Your hairline, crown, and underneath layers may not match. Note your most common pattern, then your secondary one.

Give it a few washes to get a real read, especially if you've been using heavy products or heat that can stretch the curl temporarily.

Why Your Hair Type Guides Products and Styling

Knowing your type points you toward what your hair generally needs, though it isn't the whole story (porosity and density matter too).

• Types 1–2 tend to get weighed down fast, so lighter, water-based products and mousse usually win over heavy butters.
• Type 3 loves moisture and definition from creams and gels, with scrunching to encourage the spiral.
• Type 4 is naturally the driest because oils travel down the tight coils slowly, so richer creams, sealing oils, and very gentle detangling help most.

Think of your type as a starting lane, not a cage. You'll still tweak based on how your hair actually behaves.

Can my hair type change over time?

Yes, it can shift. Hormones (including pregnancy and menopause), certain medications, heat damage, and even some chemical treatments can loosen or alter your pattern, sometimes temporarily and sometimes for good. Aging changes texture too. If your usual routine suddenly stops working, it's worth re-checking your pattern on freshly washed, air-dried hair. This is general information and not medical advice, so if a sudden change worries you, a doctor or dermatologist is the right person to ask.

Putting It All Together

Start by finding your number, then notice your subtype, then watch how your hair actually responds. Pairing your type with your porosity gives you a much fuller picture, and from there building a routine feels doable instead of overwhelming.
