Which Hair Color Fades The Fastest?
Red hair color is known to fade the fastest among all hair colors. Red pigments molecules are the smallest in size compared to other colors, making them more prone to wash out quickly from the hair shaft. The ultraviolet (UV) light from the sun can also cause the hair color to fade faster, and since red hair has larger pigment molecules, the sun can break them down even more easily. Therefore, if you have red hair, it’s important to use a color-protecting shampoo and conditioner, avoid excessive sun exposure, and limit your hair washing to preserve your hair color.
