Ever wondered how supermodels get that glossy, light-reflecting, off-duty hair that somehow always looks good? It's the kind of shine that looks smooth, healthy and effortlessly perfect in a way that feels almost unattainable. But as it turns out, Gisele Bündchen's signature shine trick is surprisingly simple (and very affordable). A source told Us that Bündchen relies on the Garnier Fructis Diamond Shine Spray to get that sleek, model-off-duty finish. It's designed to smooth the hair's surface and boost light reflection on almost any style.
