How do you shave your armpits so you cant see the hair follicles?

Shaving will not do. You can try to exfoliate and then shave (which will help slightly but if you have sensitive armpits I don't suggest this because it could irritate the follicles and cause grotesque bumps that will be incredibly painful and can be prone towards infection such as sickle cell anemia.) If you want them to show no signs of hair you have to get a pit wax by a real seasoned professional. Don't do it yourself unless you happen to be a real seasoned professional. You could try Nair but it smells bad and is messy. Or just grow it out and don't worry about it.
