Toppik is a unisex styling product that effectively covers hair loss and adds volume to thinning, flat hair. Toppik hair-enhancing fibers are composed of tiny microfibers that are easy to apply to the hair. Thanks to advanced manufacturing processes, the fibers adhere to the hair shaft using electrostatic attraction. Toppik is made with the same organic keratin as hair, making it a natural and completely harmless product that won't cause any damage. Simply apply and comb to make your hair look fuller and thicker! It blends seamlessly into the hair, leaving no trace and won't stick to the scalp or stain clothes! The volume effect also effectively covers oily scalp, a common concern for many men and women. This large pack of Toppik contains 27.5 grams and will last approximately 70 days.
