I agree with the other two girls. However, I think it CAN help. Only because hair seems to trap sweat more, or at least cause less antiperspirant to be applied -directly- to the skin, which is what blocks the sweat from coming out in the first place. This is probably gross, but I've noticed once or twice that if I don't shave it for like a week or so when I'm lazing around the house, even though there's not much there, the hair tends to trap in sweat more and I'll notice any smell quicker than if I've just shaved.
So I don't know, consider it an experiment, haha. Shave it and see if you notice a difference. If there's no change, it grows back anyway. No harm done.
kerotinocyte roots are not the same as the sebaceous glands. shaving perhaps will help with hygeine but other than that, over sweating might have something to do and probably with homeostasis in the body
