Toppik® fibers are made of all natural organic keratin protein, the same protein that hair is made of. The fibers in Toppik® are charged with static electricity so they intertwine with your own hair and bond securely. Just shake the Toppik® fibers into your thinning areas, whether at the front, crown, or sides. In seconds you’ll see the effect of thousands of tiny protein fibers locking on to your thinning hairs. They stay in place all day, all night, through wind, rain and sweat. It’s the “secret weapon” used by millions of men and women around the world.
