Guy has a single remedy for hands (8)
I believe the answer is:
manicure
'hands' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'guy has a single remedy' is the wordplay.
'guy' becomes 'man ' (guy can informally mean a man).
'has' is a charade indicator (letters next to each other).
'a single' becomes 'I' (one).
'remedy' becomes 'cure' (synonyms).
'man'+'i'+'cure'='MANICURE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for manicure that I've seen before include "Trim" , "Care of hands and fingernails" , "Cosmetic care of the hands" , "A numeric approach to care of the hands" , "Hands/nails treatment" .)
