Droga5 New York tests consumers' Hair-Q with Can You Tell, a series of wacky online quizzes asking visitors to decipher which of two lookalike models were styled by Suave's Professionals haircare line, or with professional salon brands. From the looks of it, requirements for the models used went way beyond just looking good, as they undergo everything from a pillow beating and workout, to a windstorm. The continuing effort, which actually launched in the spring, awards those who take the tests with coupons discounting products in the Professionals line.
