Leaf lettuce will continue putting up new leaves if you either cut off whole outer leaves or give the whole plant a little haircut and take maybe the top half.

All lettuce tends to get bitter as it gets older, so it;s good to keep planting seed at intervals and discard the older lettuce plants once they get spindly and send up flower stalks, if you haven't used them already. Lettuce is best when young, sweet, and tender. Never sow lettuce seeds all at once.
So head lettuce you mean like ice berg? Most of my little lettuce is red leaf, butter, romaine (I think) and a frilly green one. It was a 6 pack. I should try the seeds. I have them in containers because the snails are so bad here. right now they are all about 3 inches tall and looking very pretty.
