Can anyone tell me what the difference is between plucking, waxing and tweezing in terms of what effect it has on hair growth etc? I have some very corse dark hairs on my chin which I have had for a while and I tend to pluck them. I have been told not to do this as it makes them even more corse. But why does waxing not have this effect? are the hair not being pulled out from the root the same? And why is it ok to tweeze eyebrows and it doesn't make them corse?
