The process of lift in hair coloring works by breaking up the melanin, which is responsible for giving hair its natural color. This allows for new color pigment to replace the existing one and create a lighter or different shade. Option A, depositing color, involves adding color to the hair without altering its original shade. Option B, equalizing porosity, is a conditioning treatment that helps to even out the hair's ability to absorb color. Option D, replacing missing colors, does not accurately describe the process of lift, as it is not just replacing missing colors but rather transforming the existing color.
