Sometimes tiny hairs get trapped under the skin's surface by dead cells. A light scrub with a loofah before shaving will exfoliate and free hidden hairs so you can remove them in one clean sweep. If you get prickly hairs, use a moisturizer with urea or glycerin (like this one from Eucerin, which has both) to soften and help them lay flat, says L.A. dermatologist Jessica Wu.
