blue rinse

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

'hair colouring' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'nebuliser sprayed' is the wordplay.
'sprayed' indicates an anagram (I've seen this in other clues).
'nebuliser' with letters rearranged gives 'BLUE-RINSE'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
