In early stages you can just pull them off, as they wont have produced even a single spore of pollen yet. As long as you use something sharp (fingernails, for example) and cut them off as close to the stem as you can, then youll cause minimal damage to the plant. If youre still worried about harming the HeShe, then use a small pair of scissors.
Also, hermie plants tend to produce female seeds... but feminised seeds have a massive chance of turning hermie for some reason.
