I noticed Kérastase is sold at my local drugstore. Is this okay to buy?

Diverted products can be counterfeit, diluted formulas, or old, expired formulas that may not be safe to use. Contaminated or counterfeit products could cause irritation or even infection. If you buy our products in a supermarket, drugstore or any other outlet other than this website or a Kérastase Consultant Salon, we cannot guarantee that it is an authentic Kérastase product. For any diversion related inquiries or to report diversion, please contact [email protected].
