Ever wondered, "What's my hair type?" Understanding your hair type is the first step towards maintaining healthy, beautiful hair. It helps you choose the right products and treatments, and creates a foundation for a consistent hair care routine. Let's dive into the world of hair types, their characteristics, and how to determine yours.
Understanding Hair Types
Hair types are primarily categorized by the shape of your hair follicle, which determines the diameter of your hair strand. This system was developed by Dr. Susan C. Walker and is widely recognized in the hair care industry. It's known as the Walker System, and it classifies hair into four main types: I, II, III, and IV.
Type I: Straight Hair
Type I hair is straight and has a round, circular shape. It's further divided into three subcategories:

- 1A: Very fine and thin, with a high shine. It's often limp and lacks volume.
- 1B: Medium texture, with some volume. It's straight but may have a slight bend at the ends.
- 1C: Thick and coarse, with a low shine. It's straight but may have a subtle wave.
Type II: Wavy Hair
Type II hair has an oval-shaped follicle, which gives it a wavy texture. It's also divided into three subcategories:
- 2A: Fine and thin, with a high shine. The waves are loose and barely there.
- 2B: Medium texture, with more defined waves. It has some volume but can still be prone to limpness.
- 2C: Thick and coarse, with a low shine. The waves are tight and resemble an 'S' shape.
Type III: Curly Hair
Type III hair has a flat, oval-shaped follicle, which results in tight curls. It's further divided into two subcategories:
- 3A: Loose, corkscrew curls. The curls are about the size of a pencil.
- 3B: Medium-sized, springy curls. The curls are about the size of a finger.
Type IV: Kinky Hair
Type IV hair has a flat, oval-shaped follicle, like Type III, but the curls are even tighter and more densely packed. It's further divided into two subcategories:

- 4A: Very tight, densely packed coils. The coils are about the size of a crochet hook.
- 4B: Tight, zigzag-shaped coils. The coils are about the size of a sewing needle.
Determining Your Hair Type
Now that you're familiar with the different hair types, it's time to determine yours. Here's a simple method:
- Wash your hair to remove any product buildup.
- Let your hair air dry naturally, without touching it. This helps to reveal your hair's natural texture.
- Once your hair is completely dry, observe the shape of your hair follicle. This is the most accurate way to determine your hair type.
If you're still unsure, you can also look at the shape of your hair strand. Straight hair is round, wavy hair is oval, curly hair is flat and oval, and kinky hair is flat and oval with a very narrow opening.
Remember, hair type is just one aspect of your hair's unique characteristics. Your hair's porosity, density, and texture also play significant roles in your hair care routine. But understanding your hair type is a great starting point for healthy hair.
