Curl Types 2a to 4c Explained
Why do some products work wonders for others but not for you? Often, it's because of your curl type. Here's how to determine your type – and which products are truly right for you.
Quick Answer
Curl types are categorized into 2 (waves), 3 (curls), and 4 (coils) – each with a, b, and c to indicate intensity. Your type determines how dry your hair is, how much moisture it needs, and which products work best.

How do I determine my curl type?
The best way to determine your curl type is after washing – without products, while the hair is still damp. This way, you see the natural structure, untainted by styling products.
Note: Multiple curl types on one head are normal. Base your care on the driest area.
Type 2: Waves (2a, 2b, 2c)
2a: Light, loose S-waves. Usually fine hair, little frizz. Products can quickly weigh it down – always choose light formulations.
2b: Defined S-waves, straighter at the roots, wavy from mid-length. More volume, slight frizz possible.
2c: Strong waves, almost curly. Tends to frizz and needs more moisture than 2a and 2b.
Type 2 hair needs light products that define without weighing it down. Creams or oils that are too heavy will make waves flat and greasy. The goal: provide moisture without suffocating the hair.
Type 3: Curls (3a, 3b, 3c)
3a: Large, loose spirals. Often shines well, prone to frizz in humidity. Needs moisture and definition.
3b: Medium-sized, well-defined curl spirals. Dries out faster, greatly benefits from deep conditioning. The most common curl type in Central Europe.
3c: Tight, springy curls. Very prone to dryness, needs intensive moisture and gentle care.
Type 3 hair needs a balanced routine: enough moisture for definition, enough hold for elasticity.
Type 4: Coils & Afro-Texture (4a, 4b, 4c)
4a: Tight coils with a visible S-curve. Very dry, needs intensive moisture and sealing oils.
4b: Sharp Z-patterns instead of round spirals. Very dense and dry – moisture is the top priority.
4c: Tightest texture, hardly visible pattern without care. Extremely prone to shrinkage and dryness. Needs the most intense moisture and sealing of all curl types.
Type 4 hair loses moisture the fastest. Intensive, rich care is not a luxury – it's a necessity.
Hair Care Routine by Curl Type – 3 Steps
After washing, without products, observe while damp. Compare several areas – roots, mid-lengths, and ends can be different.

Wash → Conditioner → Leave-In: this is the basis for all types. From Type 3b: Deep conditioning once a week. From Type 4: deep conditioning twice a week recommended.
Frequently Asked Questions about Curl Type
Can my curl type change?
Yes. Hormonal fluctuations, haircuts, heat treatments, and care all influence the structure. Curls often change after pregnancy or during puberty as well.
What if I have multiple curl types on my head?
That's normal and even common. Care for your hair according to the driest, most sensitive area – then all zones will be well-cared for.
Is curl type the most important factor in product selection?
Not solely. Porosity and hair density also play a role. However, curl type is a very good starting point – especially if you don't know where to begin.
Why don't expensive products work for me?
Because it's not the price that matters, but the formula. A product developed for Type 4 can weigh down Type 2 waves – no matter how high-quality it is. Know your curl type, then choose your product.
