Understanding Your Curly Hair: Identifying Your Curl Type Before embracing your natural curls, it's crucial to know your curl type. Curls come in various forms, ranging from 2A to 4C, and each type requires different techniques to keep them healthy and beautiful. Straight hair has a round shape, while curly hair has an oval shape, which causes it to be more fragile and prone to breaking. Knowing your curl type will help you choose the right products, routines, and hairstyles for your hair's unique needs.
