Deva 101: Hair Texture vs. Density

Get excited, because we’re back with another post about the science behind your hair! If you haven’t read our post all about the structure of your hair, check it out here.

Today, we’re going to dive into what hair texture and density means and the difference between them.

Hair Texture

Hair texture is a term used to describe the thickness or width of each individual hair strand. It’s important to keep in mind that hair texture does not determine your density, or how much hair you actually have.

There are three basic hair textures: fine, medium, and coarse. The easiest way to determine your own hair texture is by taking a single strand and laying it flat on a white piece of paper.

 If your hair is not easy to see or feel between your fingertips, appears thin, and doesn’t hold styles well, you have fine hair texture.

If your hair is visible, not hard to feel between fingertips, appears full, and holds styles fairly well, you have medium hair texture.

 Lastly, if your hair is highly visible, easily felt between fingertips, appears very full, and holds styles very well, your hair texture is considered coarse.

It’s also important to note that hair texture does not define curl pattern. The amount of natural curl a hair has is determined by its cross-sectional shape. And curls are formed based on the shape of your hair follicle. Essentially, the rounder your hair follicle is, the straighter your hair is going to be. So, if someone has perfectly round hair follicles, their hair is most likely going to be straight. If their follicle is flatter or more oval shaped, they will have curly hair. It’s interesting to think about curls like this, right?!

Hair Density

The term hair density is used to describe how much hair per square inch is present on your scalp.

Just like texture, there are three basic density levels: thin, average, and thick. To find your own hair density, gather the front area of your hair and pull it over to the side.

If your scalp is clearly visible through the strands, you have thin hair density.

If your scalp is neither clearly visible nor hard to see, you have average hair density.

Lastly, if your scalp is not clearly visible, you have thick hair density.

Once again, density does not determine texture. That means that’s it’s normal for someone to have thin, coarse hair. Make sense?
