Bleach your hair before rainbow dyeing, and try to bleach it to the lightest color without damaging your hair quality.
Blow dry your hair. If it is wet, the color of the hair dye paste at the back is not easy to attach to the hair. Then divide the hair into large triangular parts along the diagonal.
Starting from the lowest part of the hair, apply the hair dye cream of the desired color, or gradient or overlay the color, and the hair stylist skillfully blends together.
Finally, when it comes to the hair color on the top of the head, use soft colors such as pink, blue and purple.
After the whole coloring is completed, let the hair stand for 30 minutes and wash off the hair dye cream.
