Boy hero getting good, dyeing hair? (7)
I believe the answer is:
tinting
'dyeing hair?' is the definition.
'tinting' can be an answer for 'dyeing' (tinting is a kind of dyeing). I am unsure of the 'hair?' bit.
'boy hero getting good' is the wordplay.
I cannot really understand how this works, but
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
The remaining letters 'tintin' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tinting that I've seen before include "Giving colour to" , "adding colour" .)
