Tough love, including current arrangement of locks (6)

Ross

I believe the answer is:

hairdo

'arrangement of locks' is the definition.
(I've seen this before)

'tough love including current' is the wordplay.
'tough' becomes 'hard' ('hard' is associated in meaning with 'tough'**).
'love' becomes 'o' (In tennis, 'love' means 'zero').
'including' means one lot of letters goes inside another.
'current' becomes 'i' (symbol for electric current).
'hard'+'o'='hardo'
'hardo' going around 'i' is 'HAIRDO'.

(Other definitions for hairdo that I've seen before include "Arrangement of locks" , "Eg, beehive or mullet" , "What one may have expected from 'Sweeney Todd'" , "Style for one's crowning glory" , "Say, crew cut" .)

I've seen this clue in The Telegraph.
