Imagine 3B hair as really bouncy and curly hair. It's like when you take a straw and wrap your hair around it, and when you let it go, you get those fun, springy curls.
So, 3B hair is all about having those well-defined, spiral-like curls that can be super pretty and eye-catching. It's curlier than 2C hair, which has waves mixed in, but not as tight as 4C hair, which has really tight curls.

Curl size: pencil or straw.
