For example: there are 30% blue silk, natural hair color 3 degrees, policy color 5 degrees mahogany color.

Solution: 5.1 gray base color + 6% hydrogen peroxide milk 1:1 distribution, after 30-45 minutes of steady coloring, then: "[Policy color (5 degrees of red nature) + red object color] + 6% Hydrogen peroxide milk" 1:1 and then color for 30 minutes. Let's comment on the question of hair dyeing: 1 2 3 4 5 6 7 8 9 10 The international color system is expressed in ten shades, with 7 degrees as the light transmission point, 6 , 5, 4, 3, 2, 1 shade of hair, the light will reflect light under the light. 8, 9, 10 shades of hair and light through.

Therefore, when the policy color is below 6 degrees, it is necessary to cover the blue silk and then dye the policy color. The choice of the base color of Gai Qingsi: choose natural color N series for linen color, choose gray color A series for red and purple, so as to avoid the interference of coloring! Three, the color is not accurate 1, (virgin hair dyeing) factor: Does the color of the natural hair dye interfere with the natural melanin pigment? The color layer structure of natural melanin pigment: 1 2 3 4 5 6 7 8 9 10 1 blue black 2 dark brown 3 purple red 4 red purple 5 red 6 orange red 7 orange 8 yellow orange 9 yellow 10 golden A, when dyeing hair for the first time, If the policy color is at 4 degrees → choose purple color B, when the hair is dyed for the first time, the policy color is at 5-6 degrees → choose red or orange-red color C, when the hair is dyed for the first time, the policy color is at 7 degrees → choose orange color Series D, when the hair is dyed for the first time, the target color is at 8 degrees → choose linen or golden yellow color system 2, the hair that has already been dyed, and then dye a new color, resulting in color disturbance, which will cause the target color to be inaccurate. a. For example: the existing color of the hair is 6 degrees red after being checked against the light, but the customer chooses 5 degrees purple.

Assuming direct dyeing, the effect will be: purplish red b, for example: the existing color of the hair, after checking against the light, it is 8 degrees yellow, and the customer chooses 5 degrees purple. Assuming direct dyeing, the effect can be obtained: 3 degrees of natural black c, for example: the existing color of the hair, after checking against the light, it is 8 degrees of yellow, and the customer chooses 6 degrees of red.
