My mom has black, fine, super soft, 2a hair. My dad had brown, very curly (think 3b). My dad even had dreads before I was born, he called his hair "the white-boy Afro", now it is all shaved off. As a kid, he had blond straight hair. But around 12, in family pictures you can see one curl that stuck up. His hair also turned brown. Eventually, his hair became like mine but tighter. Like my dad, I had straight/wavy (2a), brown hair, and I got some curls around puberty. Now I have 2b at the back with 2c underneath, and 3b corkicelli and loose corkscrews in the front.
