Question: what is 3a and 3b hair?
Answer: 3B curls are coarser, springier, and tighter than 3A curls, and they usually have the circumference of a Sharpie marker or your index finger. ... Being in the middle of the type 3 spectrum means your curls could also have a mix of 3A, 3C, or, hell, even 2C (wavy/curly) textures, but don't let that overwhelm you.
