Use Pastels to achieve beautiful hair color. VIVIDS Pastels have four delicate shades that can be used alone or combined with other VIVIDS shades for multidimensional hair color. The ChromaSilk collection is a semi-permanent hair color that can be mixed with any VIVIDS shade without developer, and for best results, use PRAVANA PURE LIGHT series to pre-light hair at the lifting level. Rinse with cool water and condition with care.
