'beehive' is the definition.
The definition and answer can be both body parts as well as being singular nouns.
Maybe there's a link between them I don't understand?

'locks using a distinctive method' is the wordplay.
'locks' becomes 'hair' (locks can mean hair).
'using' is a charade indicator (letters next to each other).
'a distinctive method' becomes 'style' (I can't explain this - if you can you should believe this answer much more).
'hair'+'style'='HAIRSTYLE'

'for instance' acts as a link.
