I would say 2b also. wavy/curly hair can be hard to categorize, especially when it changes from one day to the next.
My hair ranges from 2a to 2c depending on the weather, products used, and various other factors. So I put myself in the middle as 2b.
Type 2b. Wash: WEN pomegranate or fig. Leave-in conditioner: Alaffia beautiful curls for wavy hair, Spiral Solutions Protein spray. Style: Curls In A Bottle, Ecostyler, or KCCC.
