Can Naturtint hair colors be used on previously colored or processed hair?

Generally, Naturtint permanent hair color can be applied over most other permanent hair colors except for metallic containing progressive dyes. For best results, wait 2–3 weeks between permanent coloring treatments.

If you perm or relax your hair, wait 2-3 weeks after your treatment before applying Naturtint permanent hair color.

Suppose you have applied demi-permanent, semi-permanent, a temporary color rinse, hair mascara, or henna to your hair; in that case, you must wait until those coloring products have entirely washed out or grown out of your hair. Otherwise, your coloring results may not be as expected.

Before applying Naturtint hair color, perform a strand test to ensure you like the color.
