Toppik Hair Building Fibres are microfibers made of keratin protein, the same protein that makes up human hair. These electrostatically charged fibers cling to existing hair, instantly making it look thicker and fuller. Ideal for concealing areas of thin or thinning hair, balding patches, or receding hairlines. The application is simple and the results appear completely natural, blending seamlessly with your existing hair color and texture. This product is designed to provide a cosmetic solution for sparse areas, boosting confidence with immediate visual improvement.
