A little phone call from the hairdresser's? (7)

I believe the answer is:

ringlet

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(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" .)
