Hint made winning like losing one's hair (4,2,3)
I believe the answer is:
thin on top
'losing one's hair' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'hint made winning' is the wordplay.
'made' is an anagram indicator.
'winning' becomes 'ontop' (I've seen this before).
'hint' anagrammed gives 'thin'.
'thin'+'ontop'='THIN ON TOP'
'like' acts as a link.
Can you help me to learn more?
(Other definitions for thin on top that I've seen before include "not so hairy now" , "with less than full head" , "Balding (colloq.)" , "developing a shine for the Head?" , "Result of losing hair, balding" .)
