Toppik Hair Building Fibers are black coloured keratin protein fibres for enhancing the appearance of fine or thinning hair. They are designed to blend with existing hair and wash out with shampoo. Product details Black shade in a 55g container. Made from coloured keratin protein fibres. The fibres are intended to withstand wind, rain and perspiration. The product removes with shampoo. Care instructions Close the container and store it away from moisture when not in use. Directions Use only on completely dry hair; towel-dry, blow-dry or air-dry the hair before application. Hold the container 2-3 inches above the areas to be enhanced and shake the fibres over the desired spots with the bottle opening facing completely downward. Pat the hair to disperse the fibres, then use an open plastic non-bristle brush or comb to style. Add more fibres and pat or brush if further coverage is needed. Toppik Fibrehold Spray may be lightly applied to help lock the fibres in place.
