'frizz-free' originates from the English word 'frizz,' which refers to tightly curled or unruly hair, combined with 'free,' indicating absence.

The term 'frizz' has been used in English since the 17th century to describe tightly curled hair, and 'frizz-free' emerged as a modern term to describe hair products that eliminate frizz.

Initially, 'frizz' referred to tightly curled hair, and 'frizz-free' evolved to describe hair that is smooth and without frizz.
