What is green over blue hair?

Green over blue hair is a hair color trend that combines shades of green and blue to create a unique, eye-catching color. The technique involves dyeing the hair with blue pigment first, then layering green pigments on top to create a dimensional effect. The combination of blue and green can create different shades, such as teal or turquoise, depending on the proportions of the two colors used. This hairstyle is popular among those seeking a bold and edgy look. Maintaining green over blue hair requires regular touch-ups and the use of color-safe shampoos and conditioners to prevent fading.
