The Vibralite Color Ring is used for the Raquel Welch Vibralite Synthetic Hair shades. Vibralite colors are specially formulated to simulate the natural look and feel of protein-rich hair. Similar in both look and feel to human hair, each Vibralite color is made up of many different shades that are subtly blended to look like natural, human hair. The wide color selection reflects the multi-tonal shades that are requested in todays most fashionable salons. This low-maintenance fiber bounces right back, ready-to-wear after washing because the style is heat-sealed into the fiber.
