Toppik Hair Building Fibers, made of colored keratin protein, blend undetectable with existing hair strands to instantly create the appearance of naturally thick, full hair. Hair building fibers (or sometimes known as hair filler fibers) are a completely different approach to building thicker hair while immediately providing the illusion of the same. They are electrostatically charged fibers made from different materials. The higher quality ones are made of natural fibers.
