Make miserable, good-looking person cut hair (8)
I believe the answer is:
distress
'make miserable' is the definition.
(to distress someone is to make them miserable)
'good-looking person cut hair' is the wordplay.
'good-looking person' becomes 'dish' (dish can informally mean an attractive person).
'cut' means to remove the last letter.
'hair' becomes 'tress' (tress is a kind of hair).
'dish' with its final letter taken off is 'dis'.
'dis'+'tress'='DISTRESS'
(Other definitions for distress that I've seen before include "Peril" , "Affliction" , "Adversity" , "Sadden" , "Upset" .)
