Identify Your Hair Type: A Practical Guide

Two people can both have "curly hair" and need completely different routines. Type alone isn't enough — you need the full picture.

The Andre Walker hair typing system (1A through 4C) is the starting point most people know. It describes curl pattern — straight, wavy, curly, or coily — and how tight that pattern is. But pattern is only one of five variables that determine what your hair actually needs.

The full picture: pattern (1-4 A/B/C), density (how many strands per square inch), thickness (how thick each strand is), porosity (how the cuticle behaves), and length. A fine, low-density 3A is very different from a thick, high-density 3A even though they share a pattern.

This guide breaks down each variable, shows you how to measure it without lab equipment, and explains why two people with "the same" hair type often need opposite products. Start with the pattern article, then add layers from each subsequent guide.

Curl pattern (1-4 A/B/C)

Pattern is the entry point — what most people mean by 'hair type'.

Density and thickness

Two different things — most people confuse them.

Porosity and elasticity

Even more important than pattern for product selection.

Building a routine for YOUR combination

Once you know all five variables, the routine writes itself.

Frequently asked

What's the difference between density and thickness?

Density = number of strands per square inch (sparse vs full). Thickness = diameter of each individual strand (fine vs coarse). You can be fine and dense, or thick and sparse — they're independent.

Can my hair type change?

Pattern can change with hormones (pregnancy, menopause), severe damage, or aging. Density and thickness change slowly over years. Porosity changes with damage, often within weeks. So yes — what worked at 25 may not work at 40.

Do I need to know all five variables?

For a basic routine, pattern + porosity is enough. For optimal product selection — especially if you've had recurring problems — knowing all five removes guesswork.
