Shaving bumps, called milla, occur when you shave too close or the razor cuts tightly curled hairs in the beard, making the hairs curl back into the skin. With a skin condition such as Psoriasis, Zirh suggests you get a recommendation from a Dermatologist. Ingrown hairs occur while shaving. The hair is turned and pushed back into the skin and can become infected. Zirh is available in some of the finest department stores and specialty stores.
