What is my hair type?
Hair types are usually described with the system popularized by stylist Andre Walker, which sorts hair into four families by curl pattern. Type 1 is straight, type 2 is wavy, type 3 is curly and type 4 is coily. Each family splits into A, B and C, from the loosest to the tightest pattern. So 2A is a soft, barely there wave and 4C is a tight zigzag coil with lots of shrinkage.
Curl pattern is only part of the story, though. Two people with 3B curls can need very different products if one has fine, low porosity hair and the other has coarse, high porosity hair. That is why this quiz also checks strand thickness, density and porosity.
Hair type chart
| Type | Pattern | What it looks like |
|---|---|---|
| 1A, 1B, 1C | Straight | No curl, from pin straight and fine to straight with a slight bend |
| 2A, 2B, 2C | Wavy | S shaped waves, from loose and soft to deep and defined from the roots |
| 3A, 3B, 3C | Curly | Defined ringlets, from chalk sized loops to tight pencil sized corkscrews |
| 4A, 4B, 4C | Coily | Tight coils and zigzags with lots of shrinkage |
What is hair porosity?
Porosity is how easily your hair absorbs and holds moisture, and it depends on how open the outer cuticle layer is. Low porosity hair has a tightly closed cuticle, so water beads on it and products sit on top. High porosity hair has a raised cuticle, often from bleaching, heat or genetics, so it drinks up moisture and loses it just as quickly. Medium porosity sits in the happy middle.
A quick at home check is the float test: drop a clean, product free strand into a glass of room temperature water. If it floats for several minutes, your porosity is probably low. If it sinks slowly, it is medium, and if it sinks straight away, it is high. The absorption question in the quiz is usually more reliable, because oils left on the strand can skew the float test.
Thickness and density are not the same
Thickness is the width of a single strand, while density is how many strands grow on your head. You can have fine strands with high density, which looks full but tangles easily, or coarse strands with low density, which feel thick but show more scalp. Knowing both helps you choose cuts and products: fine hair suits lightweight mousses, while dense, coarse hair can handle rich butters and creams.
