Type 4 hair
Coily hair with tight coils or zigzags, often called afro-textured hair, from 4A coils to 4C.
Also: coily hair, kinky hair, afro-textured hair, 4A, 4B
Type 4 is coily hair, often called afro-textured or kinky hair. 4A forms small, tight S-shaped coils; 4B bends in sharp zigzags with less defined curls. Coily hair is the most fragile type, because each bend is a weak point, and it can shrink to a fraction of its stretched length. It holds shape very well, which is why it suits braids, twists, locs, Bantu knots, sculpted afros and other styles that hold for weeks.
