Hairdo for every male (4)
I believe the answer is:
perm
'hairdo' is the definition.
(perm is a kind of hairdo)
'every male' is the wordplay.
'every' becomes 'per' (I've seen this in other clues).
'male' becomes 'm' (common abbreviation).
'per'+'m'='PERM'
'for' is the link.
(Other definitions for perm that I've seen before include "Russian city and hairstyle, in short" , "A hairdo; Urals city" , "locks far from straight?" , "combo in pools" , "Football pools forecast - wavy hairdo" .)
