Abstract
Abstract Disclosed is a shaving preparation to aid in prevention and treatment of PFB (ingrown hairs), which includes from about 0.1 to 6% by weight salicylic acid; a glucocorticoid in amount effective to reduce inflammation; and from about 0.5 to 5% by weight sulfur. In the shaving preparation the glucocorticoid can be, for example, triamcinolone acetate (about 0.025 to 0.1% by weight) hydrocortisone USP (about 0.1 to 2.5% by weight), or hydrocortisone acetate USP (about 0.1 to 2.5% by weight), and the sulfur can be in precipitated, sublimed or colloidal form. A number of other ingredients can also be included. Alternatively, the preparation can be separated so the active ingredients are in two or three separate parts, which are applied at various stages in the shaving process. The preparation is to be applied to the skin surface before and/or after shaving.
