Toppik Spray – A fine mist specifically developed to increase the bond between Toppik Fibers and thinning hairs. Entirely free of lacquer, this formula uses sophisticated cosmetics grade resins to join thinner hair and Toppik fibers naturally and durably. Naturally derived ingredients soften and condition both hair and fibers for a completely natural appearance. Sunscreen agents are added to protect hair from damaging ultra violet rays. PH balanced to 5.5 for optimum results with Toppik Hair Building Fibers. You may brush after drying for softer styles with ample fiber-holding power.
