Treated hairily, in a fashion? (6)
I believe the answer is:
styled
'treated' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
'hairily in a fashion?' is the wordplay.
I cannot quite understand how this works, but
'fashion?' could be 'style' (fashion is a kind of style) and 'style' is found in the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for styled that I've seen before include "Fashioned" , "Designed, arranged" , "Designed; designated" , "Called; (hair) shaped" .)
