dandruff: [16] The word dandruff (or dandriff, as it commonly used to be) first appears, out of the blue, in the mid 16th century, with no known relatives. Its first element, dand-, remains utterly obscure, but the second part may have been borrowed from Old Norse hrufa or Middle Low German rōve, both meaning ‘scab’ (Middle English had a word roufe ‘scab, scurf’, and modern Dutch has roof).
dandruff (n.)
1540s, first element obscure, second element is Northumbrian or East Anglian dialectal huff, hurf "scab," from Old Norse hrufa, from Proto-Germanic *hreufaz, source of Old English hreofla "leper."
