How Long Do You Leave Clairol Professional Hair Color in Your Hair?

For a standard color application, leave Clairol Professional hair color in for 30 minutes, and to completely cover gray, 45 minutes is recommended. During the coloring process, the first 15 minutes the color is on the hair allows it to open up the hair cuticle, getting it ready to accept color. The last 15 to 30 minutes allows the color to provide the maximum color deposit.

Those wanting to achieve a high-lift shade should also leave the color on for a full 45 minutes to achieve maximum lightening. Once the desired shade is achieved, rinse the hair in lukewarm water, then shampoo and condition as usual.
