Toppik Fiber Medium Blonde uses advanced keratin protein technology that clings electrostatically to existing hair, creating an immediate volumizing effect. This shade seamlessly matches medium blonde tones while concealing thinning areas, receding hairlines, and gray roots with natural-looking coverage. The formula withstands humidity and physical activity, making it reliable for daily wear across all hair types. Simply apply to problem areas for thicker, fuller-looking hair that lasts until your next wash.
