Dying hair brown to blue, also known as "bruising," involves transforming brunette locks into vibrant, captivating shades of blue. This hair coloring technique has gained immense popularity in recent years, owing to its bold and unconventional aesthetic.
The process of dying hair brown to blue typically entails bleaching the hair to lift its natural pigments, followed by applying a blue-toned dye. The resulting effect can range from subtle, iridescent hues to deep, saturated blues, depending on the desired outcome and the skill of the hairstylist.
