Fix a lot with styling brush (7)

I believe the answer is:
foxtail
'brush' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'fix a lot with styling' is the wordplay.
'fix a lot' can be anagrammed to 'FOXTAIL'.
But, I'm not clear how the anagram is indicated.
Can you help me to learn more?
I've seen this clue in The Times.
