Save money on second hairstyle (6)

I believe the answer is:

scrimp

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

'save money' is the definition.
'scrimp' can be an answer for 'save' (scrimping is a kind of saving). I am unsure of the 'money' bit.

'on second hairstyle' is the wordplay.
'on' means one lot of letters go next to another.
'second' becomes 's' (common abbreviation).
'hairstyle' becomes 'crimp' (as in crimped hair).
's'+'crimp' is 'SCRIMP'.

Can you help me to learn more?

(Other definitions for scrimp that I've seen before include "Watch the pennies" , "Use or do less than is needed, be mean" , "Pinch and save" , "Be niggardly" , "Be economical and sparing" .)
