Switch to Permanent Hair Color for Full Gray Coverage

Since the Casting Crème Gloss formula is designed only for blending and lacks the ammonia required for 100% gray coverage on coarse, resistant hair, you must transition to a permanent color product.

1. Purchase a permanent hair colorant, such as L'Oréal Excellence Crème, which is specifically formulated to penetrate and cover resistant gray hair fully.
2. Perform an allergy alert test 48 hours before your application by applying a small amount of the product to the skin as directed on the packaging.
3. Follow the permanent color application instructions provided in the kit, ensuring thorough saturation of the hair, especially at the roots and temples.
4. Allow the permanent color to process for the full recommended time to ensure maximum pigment absorption.
5. Rinse and condition your hair as instructed by the permanent color manufacturer.
6. Verify the fix by inspecting the formerly gray areas under natural lighting to ensure opaque, uniform color coverage.
