The proportioning of hair dye cream needs to be operated according to the instructions of specific products. Generally speaking, hair dye cream usually consists of two components: dye and oxidant. Dye is the color of hair dye paste, and oxidant is the chemical substance that changes the dye.
Generally speaking, the ratio of hair dye cream is 1:1 or 1:2 of dye and oxidant. This means that if you use a 1:1 ratio of hair dye cream, you need to mix the same amount of dye and oxidant together. If you use a 1:2 ratio of hair dye cream, you need to mix two times as many oxidants as the dye.
Pay attention to the following points when preparing the proportion of hair dye cream:
1. The dosage should be adjusted according to the length and density of the hair to ensure that the hair dye can be evenly applied to the hair.
2. Before mixing dyes and oxidants, they should be stirred evenly.
3. When mixing dyes and oxidants, non-metallic containers and agitators should be used to avoid chemical reactions.
4. The mixed hair dye cream should be used immediately and should not be stored for too long to avoid affecting the effect.
In a word, the proportion of hair dye should be carefully read in the product manual, and properly adjusted according to the length and density of hair to ensure the best effect of hair dye.
