Pageboy, for one (4)
I believe the answer is:
coif
'pageboy for one' is the definition.
(I know that pageboy is a type of coif)
This is the entire clue.
(Other definitions for coif that I've seen before include "Dress the hair" , "what can be made of lawn?" , "Headgear" , "Cap worn by fundamentalist Mormon women: hairstyle" , "Nun's cap" .)
