Toppik’s Spray Applicator is a convenient tool to use for applying hair fibers to existing hair. It helps apply the hair fibers to the areas where they are needed the most. It helps you carefully apply the hair fibers on the thinning hair parts and spread then uniformly all over. The equal distribution of hair fibers gives a naturally fuller look to hair. This tool can be attached to both economy and regular size bottles of Toppik Hair Fibers.
