SureThik is a unique complex of organic keratin protein that has been precision cut into tiny micro-sized fibers. These microscopic hair fibers build upon your existing hair and scalp to produce dramatic density, volume and total coverage. SureThik is made from the same organic keratin protein as your own natural growing hair. It is completely safe and an all-natural solution for both men and women. Once you have brushed SureThik in, it will be completely undetectable, leaving you with nothing but thicker looking hair!
