Can I use Madison Reed hair color if I have henna in my hair?

Henna works by coating the hair shaft with color, which makes it difficult for traditional hair color to penetrate through and deposit new color. Madison Reed does not recommend coloring over hair that has henna on it. Instead, wait until you have at least 1-2 inches of regrowth before using Radiant Cream Color. Apply only to your roots and do not pull the color all the way thru until the henna is completely grown out.
