The word 'dandruff' originates from Middle English 'dandrif', which is a combination of 'dand' (meaning to shake or to move) and 'ruff' (meaning a fragment or shred). The term refers to the flakes or fragments of skin that are shed from the scalp.
Think of 'shaking' ('dand') off 'fragments' ('ruff') from your scalp — that's what dandruff means.
