Hairdo — skullcap (4)

Ross

I believe the answer is:

coif

This clue is a double definition.

'hairdo' is the first definition.
(I know that hairdo can be written as coif)

'skullcap' is the second definition.
(coif is a kind of skullcap)

(Other definitions for coif that I've seen before include "what can be made of lawn?" , "Cap worn by fundamentalist Mormon women: hairstyle" , "Headgear" , "Nun's cap" , "Dress the hair" .)

I've seen this clue in The Guardian.
