Bow to one hairless man (9)
I believe the answer is:
archibald
'man' is the definition.
(I've seen this before)
'bow to one hairless' is the wordplay.
'bow' becomes 'arch' (both can mean to curve).
'to one' becomes 'i' (Roman numeral).
'hairless' becomes 'bald' (similar in meaning).
'arch'+'i'+'bald'='ARCHIBALD'
(Other definitions for archibald that I've seen before include "fellow" , "Scotsman" , "Boy" , "chap" , "man" .)
