Hair types
The hair a style is made from, from straight to coily.
Straight hair
Straight hair grows without a wave or curl and falls flat from root to tip. It is the most common hair type in East Asia and is widespread in many other regions
Wavy hair
Wavy hair falls in loose S-shaped bends, flatter at the root and more defined towards the ends. Typing charts call it type 2 and split it from 2A, soft and easily brushed out, to 2C, strong waves with some ringlets
Curly hair
Curly hair forms spirals and ringlets. Typing charts call it type 3, from loose 3A loops to tight 3C corkscrews about the width of a pencil
Coily and kinky hair
Coily hair, also called kinky or afro-textured hair, grows in tight coils and zigzags. Typing charts call it type 4, from 4A coils to 4C, the tightest
Fine hair
Fine hair has thin strands. It feels soft and silky, can look flat at the roots and can struggle to hold curls, braids and volume
Thick hair
Thick hair can mean wide, strong strands, or dense hair with many hairs on the head, or both. It looks full and holds braids, buns and curls well, but it can be heavy, slow to dry and bulky
Any hair
Some hairstyles work on almost any hair: straight or coily, fine or thick. The ponytail, the bun, the braid, the buzz cut and the shaved head are found on every continent, which is part of why they are among the oldest and most common styles
