What is blue rinse?

A blue rinse is a hair treatment that involves adding a blue or purple tint to gray or white hair, often to neutralize yellow or brassy tones. This process typically uses a special shampoo or rinse containing pigments that enhance the hair's brightness and give it a cooler hue. The term is commonly associated with older women who use this treatment to maintain a stylish appearance. It has become a cultural reference, symbolizing a specific demographic's beauty practices.
