Hair Types Explained: What Is 3A, 3B, 3C, 4A, 4B, and 4C?

Understanding your hair type is essential for developing the perfect hair care routine and selecting the right products and styles. This knowledge is the first step towards embracing and celebrating your natural hair. In this post, we'll help you determine the common category your hair falls under. But before we get into it, remember that all hair types are beautiful and embrace your natural hair confidently.

What Are Hair Types?

Your hair type is determined by your hair's curl pattern, which is determined by your hair follicle. The more oval and asymmetrical shaped your hair follicle, the curlier you hair; the more circular your hair follicle, the straighter your hair. Andre Walker, best known as Oprah Winfrey’s stylist, created a system to classify hair into 4 types. While Types 1 and 2 refer to straight and wavy hair respectively, today we're focusing on Types 3 and 4, which represent curly and coily/kinky textures common in Black hair.

Hair Porosity

Beyond curl pattern, hair porosity plays a crucial role in determining the best products for your hair. Hair porosity tells you how easily your hair absorbs and retains moisture. Your hair can be low porosity, medium porosity or high porosity. Check out our post on understanding porosity to determine what porosity you have and how to care for your porosity type.

Natural Hair Care Tips

Here are some natural hair care tips that everyone should follow regardless of their hair type:

  • Regular trimming: This help prevent split ends which prevent breakage and helps length retention.
  • Protect at night: Always wrap your hair in a satin bonnet/head scarf or use a satin pillowcase to prevent friction, frizz and moisture loss.
  • Hydration: Always ensure your scalp and strands are moisturised and healthy. Dry scalp and strands can cause breakage.
  • Gentle detangling: Always detangle from ends to roots using your fingers or a wide-tooth comb.
