dishevelled:  Semantically, dishevelled ‘with untidy hair’ and unkempt ‘with uncombed hair’ are closely parallel formations. Dishevelled originated as an adaptation of deschevele, the past participle of Old French descheveler ‘disarrange the hair’. This was a compound verb formed from the prefix dis- ‘apart’ and chevel ‘hair’, a descendant of Latin capillus ‘hair’ (from which English got capillary ).
In Middle English its meaning was extended to ‘without a head-dress’, and even to ‘undressed’, but its modern metaphorical application is the more general ‘untidy’. (The verb dishevel was a late 16th-century back-formation from dishevelled.) => capillary
