It’s misleading I know, for a celebrity to advertise and sometimes even say that they use a product when they don’t. In school you should learn about marketing and writing techniques known as Pathos, Logos, and Ethos. Pathos is all about hitting the consumer with emotions that they’ll respond to by buying your product. Logos is logic. It’s when a commercial present the facts, data, results, and statistics that “prove” that their service/product is the best. Ethos is about credibility. When Jessica Biel says she uses this shampoo it makes you want to too right!? That is why celebrities endorse things.
So no, Miranda Kerr and Heidi Klum don’t use clear scalp and hair, Eva Longoria doesn’t use L’Oreal Paris box color, and Jennifer Garner doesn’t use Neutrogena. Sorry! If they did they would have dry, damaged and dull locks, accompanied with bumpy and uneven skin.
p.s. Eva Longoria’s Stylist uses Redken hair color
