'hairstyle' originates from the combination of 'hair' and 'style', where 'hair' refers to the strands growing from the scalp and 'style' refers to a particular design or arrangement.

'hairstyle' evolved from the Old English word 'hær' for hair and the Middle English 'style' from Latin 'stilus', meaning a particular manner or design.

Initially, it referred to any arrangement of hair, and this meaning has largely remained the same in modern usage.
