What is the typical characteristic of semi-permanent hair color?

Semi-permanent hair color is designed to provide a temporary change in hair color without significantly altering the hair's structure. One of its defining characteristics is that it gradually fades with each wash over time. This occurs because semi-permanent color is formulated to deposit color onto the hair without penetrating the cortex, allowing it to wash out over several shampooing sessions. As a result, users can enjoy a new hue without a long-term commitment, making it an ideal choice for those looking to experiment with color or for individuals who prefer a more natural look that blends with their hair as it grows out.
