Society classifies hair into different categories. It’s called the hair typing system. People with Type 1 hair have straight, fine hair, that tends to be oily, and is hard to damage. People with Type 2 hair have wavy hair in a ‘S’ pattern. People with Type 3 hair have curly hair that can range from being in a ‘S’ pattern to kink or tight curls with a lot of strands of hair densely packed together. People with Type 4 hair have very tightly coiled hair that is very fragile and has less defined curls. There are certainly trends in different hair styles.
