Nair (hair removal)
|Owner||Church & Dwight|
The brand is mainly known for its depilatories that work by breaking the disulfide bonds of the keratin molecules in hair. This reduces the tensile strength of the keratin so greatly that the hair can be wiped away. Nair's slogans include: "The Less That You Wear, the More You Need Nair!"; "Like Never Before"; and "We wear short shorts, Nair for short shorts". The initial ad for the "short shorts" commercial won a Clio. It was based on the 1958 song "Short Shorts". Nair is a portmanteau of "No hair."
Two of the active ingredients are calcium hydroxide (slaked lime) and sodium hydroxide (lye), which raise the pH of hair, chemically breaking it down. Some formulations also contain potassium thioglycolate, which breaks down the disulphide bonds in the hair's keratin thus weakening it enough to be simply wiped away. Products such as Nair often combine softening agents such as mineral oil to help offset the harsh active ingredients.
