Depends on the herb & how far back you've cut them. Could you elaborate?

Coriander is an annual herb and will run to seed probably a lot quicker than you would like, in which case you will need to sow again at least once more this year.

Parsley is a biennual plant, so if it is growing somewhere which suits it it should carry on producing leaves this year and also for the first part of next year until it also starts to run to seed.
