Waxing, Sugaring, Nads, and threading will remove all of the visible hair by ripping it out by the root. Except in the case of threading, the outer layer of skin is often removed when the hair is removed. It can result in skin problems including ingrown hair, scarring, pigment changes, and bruising. To keep your skin clear, (and contrary to advertising claims) all of these methods must be done frequently forever. You must also wait until hair is at least 1/4" to 1/2" (about 3 weeks of growth) long for the wax/sugar/Nads "glue" to adhere to the removal strip.
Research has shown that any method that rips hair out by the root such as waxing, sugaring, and Nads type products can actually increase hair growth in hormonally dependent areas such as the upper lip, chin, breasts, and abdomen! This is not such an issue on areas like eyebrows and legs wax away if you must and your skin can tolerate it.
