Agree to how to restyle one's hair? (6)
I believe the answer is:
permit
'agree to' is the definition.
(thesaurus)
'to restyle one's hair?' is the wordplay.
I cannot really understand how this works, but
'hair?' could be 'perm' (perm is a kind of hair) and 'perm' is found within the answer.
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
A single letter 't' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'how' is the link.
Can you help me to learn more?
(Other definitions for permit that I've seen before include "Licence -- license" , "Allow, authorise" , "Consent to, allow" , "Allow - visa" , "Let; enabling document" .)
