* Natural Oils Protection: Natural oils on your scalp act as a barrier, helping to protect it from potential irritation during the coloring process.
* Better Color Absorption: Unwashed hair can be slightly more porous, allowing the hair color to penetrate more effectively.
* No Product Interference: Clean hair can have residue from shampoos, conditioners, or styling products that might interfere with the hair color's ability to properly adhere to the hair shaft.
Important Note: Always follow the specific instructions provided in the hair color kit you are using. If the instructions say to apply to clean, dry hair, then that's what you should do.
