TOPPIK Hair Building Fibers are made from keratin protein, the same protein that naturally makes up your hair. These microfibers electrostatically cling to existing hair strands, instantly making thinning hair appear thicker and fuller. Ideal for both men and women experiencing hair thinning or patchiness, these fibers offer an immediate cosmetic solution. They blend seamlessly with your natural hair color and are resistant to wind and perspiration, offering confidence throughout the day. Application is simple: shake or spray the fibers onto the thinning areas, and then gently pat or comb to disperse and set the fibers for a natural, undetectable finish.
