Punishment after losing head inspires husband to improve (7)

I believe the answer is:

enhance

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

'improve' is the definition.
(enhancing is a kind of improving)

I don't understand the remainder of the clue.

(Other definitions for enhance that I've seen before include "To improve matters" , "'Improve, augment (7)'" , "Improve, make more attractive" , "produce better image" , "Heighten, intensify" .)

I've seen this clue in The Hindu.
