What is my curly girl hair type, hair thickness and density?

Leestijd: 4 minuten

If you would like to start the curly girl method, it is important that you know your hair characteristics. We can help you on your way in just three short articles. In addition to your curl type, hair thickness and density, we also explain in detail everything about your hair proprietary and the elasticity.

Each curl type is different, with its own characteristics. That is why it is important to determine your own hair properties, so that you can see which hair care is best for your curls. Curly hair can be divided into different curl types: wavy, curly and coily. If you know your curl type, you can adjust your routine, products and hairstyles accordingly. With this knowledge you can provide a more beautiful and healthier curl.

Is this all new to you? Then it can be quite a challenge to determine which curl type you have. Maybe you have heard of curl type 2A and 3C, for example? This image below shows what curl types there are. Can you recognize yours?


Curl type can be difficult to determine, because your natural curls are still hidden under a damaged or over-treated layer. So, it is best to determine your curl type if your curls come out all natural if you have optimized your hair routine. Your ‘real’ and healthier curls will then show themselves gently, allowing you to better judge whether you are a wavy, curly or perhaps coily type.


The numbers 2, 3 and 4 (1 is straight hair, let’s not consider this) indicate your curl type, while the letters A, B and C indicate how tightly curled your curls are. You can have a combination of two curl types that are close together.

  • Wavy or wavy hair is bendable and supple hair, the structure ranging from fine to thick, and has a clear “S pattern”. The hair is close to the head.
  • Curly or curly hair is spiral shaped. The curls range from loose, bouncy loops to tight, springy corkscrews that shine but can also fluff quickly.
  • Coily hair is usually called afro hair or kinky hair and is naturally very dry and spongy in texture. Afro hair can be soft and fine, as well as thick and coarse.

How wide is your curl: A, B or C?

The subcategories from A to C are based on the width or diameter of your wave, curl or afro pattern. A is wider, B is medium and C is the smallest of the three.


The curly girl method looks at the following five properties: hair type, density and thickness, porosity and elasticity . In addition to curl type, these characteristics are also important to determine which products and styling work best for your hair.

Density of your hair

The density of your hair means the amount of hair on your head. This is also referred to as the density of your hair. So you can have thin, medium or thick hair. You determine your hair density by grabbing a strand of hair close to your head and looking at your scalp:

  • If you can see your scalp very well, you have thin hair.
  • If you can see a little scalp, you have medium hair.
  • If you can barely see a scalp, you have thick hair.

Hair thickness

The hair thickness (also called structure) looks at the thickness of an individual hair. You can have fine, medium, or coarse hair. Keep in mind that the thickness of your hair should have nothing to do with your curl pattern. You can find out the thickness by holding one loose hair up to the light.

  • If you can see your scalp very well, you have thin hair.
  • If you can see a little scalp, you have medium hair.
  • If you can barely see a scalp, you have thick hair.

Another way to determine the thickness of your hair is to hold one loose hair between your fingers. Do you hardly feel the hair? Then you have fine hair. Do you feel the hair well? Then you have coarse hair. If it’s in between, you have medium hair.

You’re not there yet. Also read our articles about porosity and elasticity

  • This is how you find out the porosity of your hair : Porosity is about the extent to which your hair absorbs moisture and can retain it (measured by how long it takes your hair to dry after showering – is this fast or slow?). If your hair doesn’t easily absorb moisture, you need thicker, richer creams.
  • Hair elasticity: what is it and how do you test it? Elasticity is measured by pulling out your curl and determining how quickly your curl returns. Doesn’t bounce back – quickly – is a sign of lack of hydration. With an imbalance you can, for example, suffer from dry or brittle hair.


Very nice of course that you now know everything about your hair properties, but what can you do with this knowledge? In our three articles about hair properties you can read about curl type, hair thickness, density, porosity and elasticity and how to determine the properties of your hair. Now you want to know for sure: which products are best for my hair and fit the curly girl method? We will soon write an extensive article about this. Keep an eye on our website.
