Four Reasons Optima is the color of your dreams. It works as a permanent and as a semi-permanent color, never looks painted on or over-saturated even though the shades are exceptionally deep. Optima is pleasant to use with everyday salon work, as the rich formula has been designed to be very easily mixed and applied. The shades are easy to understand and easy to mix or use alone. The result is always a beautifully tone-rich and shiny color.
