Schwarzkopf got2b play it straight is a straightening blow dry kit designed to create sleek, straight styles that last for up to ten washes. Play it straight contains a special protein that helps to loosen the bonds that make hair frizzy, along with keratin, silk and wheat proteins to care for and condition hair. After shampooing, the smoothing serum should be applied to hair in sections and left for 20 minutes (25 for thick hair), followed by the sealing cream, which should be rinsed off after ten minutes. Hair should then be blow dried (and straightened if required). Hair will be noticeably smoother and faster to style.
