yup! my hair acts a lot differently than other people with 4b hair because my hair is thin in density and my strands are thin. my hair is very soft and cottony. it's not coarse and wiry. it does actually clump into waves and curls on the ends only. i don't see many people with my hair but i am definitely a 4b. i use to say 4c(z) back when i had no idea what the hell i was doing.
