When I had laser hair removal done I felt a little bit of pain so it wasn't totally painless but the laser hair removal was less painless than waxing to remove the hair.
Waxing to remove hair in my opinion and experience is more painful than the bit of pain I felt having the laser hair removal done.
I would recommend getting the hair removed using laser hair removal which is much less painful and works better than waxing to remove hair.
The pain from having laser hair removal done is kind of like being snapped by a rubber band but it's not too bad and it also depends on your pain tolerance.
