A little band for the hair (7)
I believe the answer is:
ringlet
'hair' is the definition.
(I know that ringlet is a type of hair)
'a little band for the' is the wordplay.
I cannot really understand how this works, but
'little' could be 'l' (abbreviation) and 'l' is found within the answer.
'band' could be 'ring' (a ring is a band of metal) and 'ring' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ringlet that I've seen before include "A curl - kind of tingler" , "A long tubular curl" , "Bit of hair" , "sort of lock" , "twist of sorts?" .)
