Hair Typing for Beginners

Hair Typing 101 (Part 1)
by Latoya of Busy Life, Fab Hair

Hair Type Let’s face it. Hair typing gets a bad rap. A really bad rap. It is viewed as the categorization of “good” and “bad” hair textures. Women can be found online asking others to categorize them. Stereotypes ensue and then hair typing gets a bad name. But if you think beyond the Andre Walker Typing System ( 3C, 4A, etc.), you will find that understanding all aspects of hair typing will make your hair journey much easier.

Have you ever wondered why someone’s hair may look just like yours, but the products they use don’t work for you? Or why some people are more susceptible to breakage? In this two part series, I’ll first break down hair typing terminology. In the second part, I will explain how you can use it to better understand your hair.
Black hair is very complex. No two heads of hair are alike. In fact, hairs on one head may not act alike. That is what makes us unique. But that also can be a challenge to fully understand. Our hair has various curl patterns (3C, 4A, etc.), textures, density, porosity and elasticity. It may seem very complicated, but here is the breakdown:

Curl Pattern

The is the most common system used to describe curl pattern. Essentially, most Black women have curly (3) or kinky (4) hair. The A, B and C refer to the diameter of the curl. (Although some women refer to their hair has “G” or “Z” hair. There is no such thing. They are just using that to emphasize how “kinky” their hair is.) The typing system is helpful with understanding how your hair may look if you copy a particular style. You can also infer that hair that is kinkier will be drier, because the tighter curl pattern makes it more difficult for natural hair sebum to reach the ends of the hair. You should not infer that kinkier hair is stronger. This is false. Hair texture determines hair strength, which I will discuss next.

The Quick and Easy Curl Pattern Guide:

1 = Straight Hair
2 = Wavy Hair
3 = Curly Hair
A = Curl diameter of sidewalk chalk
B = Curl diameter of a sharpie
C = Curl diameter of a pencil
4 = Kinky Hair
A = Curl diameter of a needle
B = Zigzag curl pattern

C = No curl pattern

Hair Texture refers to the thickness or diameter of the hair strand. Your hair can be fine, medium (normal) , or thick (coarse). Fine hair is delicate –with less protein structure — and doesn’t hold curls well. Fine hair is more prone to breakage, especially if it is also prone to dryness. Medium (normal) has more protein structure than fine hair, but it is more pliable than coarse hair. Coarse hair is a thicker hair strand, holds curls well, but it is less pliable than fine or medium hair.


Density refers to the number of strands on your head. Those with low density hair are more likely to have issues with scalpy twists. High density means you have a lot of hair strands. When you refer to someone’s hair as “thick”, it is normally in reference to density.


Porosity refers to how your hair strands retain moisture. If you are having issues moisturizing your hair, this is a very important concept to grasp. Low porosity hair is difficult to get moisture into the hair. Normal (Medium) porosity hair is fairly easy to get moisture into the hair shaft and retain that moisture. High porosity hair has a very difficult time retaining moisture because water enters and leaves the shaft easily. (NOTE: Overly porous hair is normally due to chemical and mechanical damage and is even more difficult to moisturize.) To test your hair porosity, place a shed hair in water and follow the guide below. It is also important to note that hair porosity can change over time due to use of chemicals, heat, and age of hair.

Quick and Easy Guide to Porosity
Low Porosity = Closed Cuticle = Hair floats in water during hair porosity test = Difficult to get moisture into hair

Normal Porosity = Cuticle layer opens enough to allow moisture = Hair take a long time to sink = Easy to moisturize and retain that moisture

High Porosity = Raised cuticle layer = Hair quickly sinks to the bottom = Absorbs water easily


Elasticity refers to the “stretchiness” of your hair, which is how much you hair will stretch and then return to its normal state. If your hair is healthy, when wet, it should stretch 50% or more and return to its normal state. Unhealthy hair may only stretch about 20% when wet. Hair that is not elastic is more prone to breakage. It is also harder to curl with rollers or heat styling tools. To test for elasticity, pull strands from at least four areas of your head. Determine how much it springs break, how quickly it springs break, and whether your hair breaks.

So there you have it! The simple breakdown of “hair typing”. As you can see, it is much more than 1, 2, 3 and A, B, C. [Sorry I couldn’t resist the rhyme.] It is also important to note, that you can have any combination of these characteristics. (So although you think your hair looks like “Ebony” when you watch her video… it’s not.)

In the next installment, take things a step further. I’ll explain why hair typing is important and how you can use this to sort through the plethora of information available on the web.

But for now… How do you think you will use this information?

    HHHAAAAIIIIIIIRRRRR!!! Ufff. I have 4 girls and each one of them has different hair. We use a variety of products, depending on the child. This was great information, and I’ll def store it for future use. I just want my kiddos to love themselves and their hair, and to be super proud of it. You hair, btw, is super cute.

      Hi Nicki!!!

      Thanks for stopping by. I’m glad you found the post helpful. We may have to chat more about your 4 girls and their hair.

    Great article. I am having problems with my hair and this article allow me to relaize my hair type and that I am low in porosity. Now only find out how to get the that porosity back.

  3. miri

    wow this article helped a lot and i just found my hair type…is 3c and 4a. i have no idea why its not just one, but we are all somewhat different in unique ways. thanks

  4. Katze

    Thank you so much for this information! I’m trying to learn as much as I can about my hair , so that it can be its healthiest! I have natural hair and love it. Best of hair luck and blessings to everyone! 🙂

    The troubled with the porosity test is we often put oils in our hair to seal it, and oil floats, therefore the hair could float for quite a long time without being low porosity. Or if you have dense or coarse strands they could quickly sink to the bottom not bc they are weighed down by the water they absorbed, but just bc the strands are heavy. Applying and retaining moisture seems it would be best found by trial and error. When and what does it take to make hair feel moisturized, not just how fast does it sink.

    I believe I have some 3c, 4a and 4 b. I have coarse and fine, tightly coiled and weirdly frizzy impervious to anything hair all mixed in. It is dense in the front and thin at certain points in the crown. I have low and high porosity. So basically I have everything and am having trouble getting a uniform pattern. Even though my hair was professionally cut, the sides and top stick out more than the area above the eyebrows. What do I do about that??!

  7. Claricia

    i have very thin hair, not straight and def not not too bad of a coarse strand, my problem is that i love the big frizzy bush and my hair just don’t seem to frizz at all, when wet it just hangs in long strands and when dry it does not curl at all. I am currently using the Dr. Miracle products for the last 3 years and my hair is nice and long, but i still want the natural Jill Scott look. Please help me as I don’t want to braid or put any unnecessary products on my hair that might cause damage

      Hi Michelle, are asking about products? You can use the search bar and search”locs” you will an article called “Dry Locs” that has tips about what products to uses and more

    Hi. I recently did the BC. And I’m wondering what products can I use to find my texture because it’s still growing like it’s relaxed.

      There are no products that will help you find your texture. Just give it some time. You’ll see more and more of your natural texture.
