Every day, you see people with a variety of hair colors and styles. But did you know that you have a specific hair type? That’s right—no two heads of hair are exactly the same.
Let’s break down the basic structure of hair:

- Hair grows from a follicle, which is bulbous and elongated. If you pull out a strand, you’ll notice a small bulge at the tip—this is the base of the follicle where cells divide rapidly and stimulate hair growth.
- Each strand of hair is composed of three layers. The innermost layer is the medulla, which is present only in thicker hair types.
- The middle layer is called the cortex. This layer gives your hair its strength, color, and texture.
- The outermost layer is the cuticle, which acts as a protective shield for the cortex. It is colorless and transparent.
- Finally, the entire strand of hair is made up of a protein called keratin. And that’s the essence of your hair!
