Loud band with extremely egregious haircuts (7)

'haircuts' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.

'loud band with extremely egregious' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'band' becomes 'ring' (a ring is a band of metal).
'with' is a charade indicator (letters next to each other).
'extremely' means to remove the middle letters (only the extremes of the word are used).
'egregious' with its centre removed is 'es'.
'f'+'ring'+'es'='FRINGES'
