Someone is grumpy! :roll:
And if you shave, hair comes back thicker and longer. :evil:
If you wax, hair stops growing in that area.
Shaving does not cause hair to grow back faster, darker or coarser. Shaving is just a method of cutting the hair at the skin surface and has no effect on the part of the hair shaft below the skin surface, which is where growth and pigmentation occur.
Waxing is just another method of "cutting" hair, except you are actually pulling the hair out of their follicles. Which can actually cause the hair to weaken thus not being able to break through the skin and therefore causing many ingrown hairs.
