What is green dye over blue hair?

Green dye over blue hair can result in a variety of outcomes depending on the shade and tone of the green and blue being used. If a bright green is applied over a darker blue, the result can be quite striking and vibrant. However, if the green is a more subdued or muted hue, it may result in a more subdued and muted look overall. It is important to note that before applying any green dye over blue hair, it is recommended to first lighten the blue hair to provide a neutral base for the green color to adhere to. This can help prevent any unwanted color mixing or patchiness. It is also important to use high-quality dye and follow proper aftercare techniques to ensure the longevity and vibrancy of the color.
