Waxing is a longer-lasting alternative to shaving for those looking for a hair removal option. The process involves the use of hard wax to pull and remove hair from the root. Whether you choose eyebrow waxing, or upper-lip waxing, you can expect results to last from two to eight weeks. Where shaving removes just the surface of the hair, leaving the follicle, waxing removes the hair from the root, leaving skin more smooth and hairless much longer. Over time, hair grows back lighter and finer, making the process less painful.
