Put too much emphasis on shaving lover's locks (10)

'put' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?

'too much emphasis on shaving lover's locks' is the wordplay.
'too much' becomes 'over' (over can mean to too great an extent).
'emphasis on shaving lover' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'locks' becomes 'tress' (both can mean a piece of hair).
'over'+'s'+'tress'='OVERSTRESS'

Can you help me to learn more?
