Applying purple hair dye over green hair can result in a variety of vibrant and unique shades, depending on the specific green and purple dyes used and the condition of the hair. Achieving the desired outcome requires careful consideration of the starting hair color, bleach application (if necessary), and dye selection.
When purple hair dye is applied over green hair, the resulting color will depend on the depth and tone of both the green and purple dyes. Darker greens may require bleaching to achieve a lighter base for the purple dye to adhere to effectively. The final result can range from deep, jewel-toned purples to lighter, more vibrant shades. Additionally, the condition of the hair can influence the outcome, with healthier hair typically producing more even and vibrant color.
