A little phone call from the hairdresser's? (7)
I believe the answer is:
ringlet
'a little' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'phone call from the hairdresser's?' is the wordplay.
'phone' becomes 'ring' (to ring on the phone).
'call from the hairdresser's?' becomes 'let' (I can't explain this - if you can you should believe this answer much more).
'ring'+'let'='RINGLET'
Can you help me to learn more?
(Other definitions for ringlet that I've seen before include "Curled lock of hair" , "Cluster of hair" , "twist of sorts?" , "A curl - kind of tingler" , "A long tubular curl" .)
