Body Hair Removal Product

let’s say you’re tired of shaving your face every day……….
and laser hair removal could mean you don’t have to shave anymore.

but you’re afraid of the thought that once you do it, you won’t ever be able to change your mind.

Is it possible to have laser hair removal of some kind that has only temporary effects?
or is it always permanent?
Is it possible to undo it and regrow facial hair?

i believe that after four years or so they hair will grow back.
