The average American man uses six personal care products a day containing more than 80 unique chemicals. Many of these chemicals are absorbed into the skin, inhaled or ingested, and the vast majority of cosmetic chemicals have not been assessed for safety. Some of the chemicals used in men's body-care products ~ from aftershaves and shaving creams to deodorants and shampoos ~ are linked to cancer, birth defects, learning disabilities and other chronic health problems.
