XFusion by Toppik is a brand exclusively designed for Hair Salons and features XFusion Keratin Hair Building Fibers. XFusion's Keratin Hair Fibers instantly create the appearance of naturally thick, full hair. The fibres are made of coloured keratin protein so they blend undetectable with existing hair strands. This helps to instantly fill in thinning hair and conceal hair loss or scalp show through. But it also works to make fine, flat hair look instantly thick and full. As the world's best known brand, the XFusion by Toppik's difference is in the fibers technology. Virtually identical to human hair and naturally magnetized with static energy, the natural keratin hair fibers intertwine undetectable with your existing hair.
