How to use

Apply the mixed dye evenly to dry, unwashed hair, starting from the roots if covering regrowth or applying to lengths for a full color change.

Dry and style as usual.

Usage recommendations

Perform a patch test 48 hours before first use to check for allergic reactions. Follow timing and mixing directions precisely to avoid unexpected results. For best coverage on resistant grey or heavily processed hair, consider strand testing beforehand and adjust processing time as indicated in the instructions.
