-Apply a product containing azulene or witch hazel to help reduce the swelling and redness that's associated with ingrown hairs. From there, coax the ingrown hair from its location with a pair of tweezers (don't pull it out, though, this will only make the ingrown hair regrow in in the same way later).
-Shave your face, legs or underarms in the shower after standing under warm water for a few minutes. This will help open up hair follicles and will soften hairs so they're less coarse to shave.
-Waxing your legs? Pull skin taut before applying the wax to make it easier to remove the strip in one clean motion. Remove leftover wax with a cotton ball
