Just the thing for a change in hairstyle? (6)
I believe the answer is:
switch
'change in hairstyle?' is the definition.
'switch' can be an answer for 'change' (switch is a kind of change). I am not sure about the 'in hairstyle?' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for switch that I've seen before include "Change round" , "Change course" , "Change position" , "birch" , "Change; false hair" .)
