Which color category fades over weeks but is not temporary?

• A. Permanent color
• B. Demi-permanent color
• C. Direct dye
• D. Temporary color

Answer: (B)

The main idea here is how long different color categories last. Demi-permanent color is designed to deposit color with little or no lifting, using a low-volume developer. Because pigment molecules are smaller and only lightly penetrate the cuticle, they gradually wash out with each shampoo. That means the shade fades over weeks. It’s not permanent, since it won’t stay forever and will fade with time, but it’s also not just temporary, because one wash won’t instantly remove it. Temporary color coats the hair surface and washes out quickly, while permanent color alters the hair more deeply and lasts until new growth appears. Direct dye sits somewhere in between but the description given—fading gradually over weeks without being temporary—fits demi-permanent best.
