Love sometimes goes to her head (5)

Ross

I believe the answer is:

livia

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

'love sometimes goes' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'her head' is the wordplay.
I cannot quite understand how this works, but
'her' could be 'liv' and 'liv' is found within the answer.
This explanation may well be incorrect...

'to' is the link.

Can you help me to learn more?

(Other definitions for livia that I've seen before include "Wife of Caesar Augustus" , "Anna ..... is the literary Liffey" , "James Joyce christened the Liffey 'Anna ....'" .)

I've seen this clue in the Evening Standard.
