What to do if your dyed hair turns black

Hair dyeing is a process of dyeing a person's own hair with other colors, so hair dyeing can only dye existing hair, and the new hair will still retain the original color of the body. So some people who have dyed their hair are very distressed because the new hair that grows is black, and it looks ugly with the dyed hair. Today I will tell you what to do if black hair grows after dyeing.

After dyeing your hair, black hair will grow on the top of your head after a while and you will need to touch up the color.

1. If your hair contains white hair and you want to use the time difference to touch up the color, you can use the target color plus the ratio of white hair to the new hair (equal proportion of hair base color) and apply it evenly on the new hair. When the new hair is close to the target color, add a small amount of base color (about 10%) to the target color and apply it on the originally covered hair. When it reaches the target color, rinse it directly.

2. If there are no gray hairs in your hair, you can apply the target color 1.5 cm away from the hair roots to the colored ends. When the new hair in the middle is close to the target color, use the target color ointment to connect from the hair roots to the hair ends and stay for about 5 minutes. When the color is even throughout your hair, start rinsing.

3. If you use a different concentration of hydrogen peroxide, you can also apply it once. Place the prepared color paste in different shaker cups. You can use 20-degree hydrogen peroxide, i.e. 6% content, to extract the new hair within 1.5 cm from the roots and the old hair. Use 30-degree hydrogen peroxide, i.e. 9% hydrogen peroxide, to extract the old hair from 1.5 cm from the roots. In this way, put the color paste in two shaking cups at the same time and apply it to each section of hair at the same time, and complete it at the same time.

4. Taking advantage of the humidity difference of the hair, you can also make the area within 1.5 cm of the hair roots and the already dyed hair slightly moist, or apply a small amount of water to the hair roots and the already dyed hair in the shaker cup (you can spray it to avoid excessive use). This can increase the humidity of the hair, reduce the concentration of hydrogen peroxide, and reduce the purity of the colorant, thereby completing a one-time touch-up.

5. While touching up the color, you can also do some hair care to keep the hair shiny. Take the egg whites of 3 eggs, stir well and brush them on your hair. Wait for 5 minutes and then rinse it clean. In this way, the protein in egg whites can ensure that the hair remains shiny for 3 days.

6. Last but not least, do not wash your hair within two days after dyeing it. Because of the effect of the solution, the hair cuticles will remain open for 36 hours after dyeing. If you wash your hair at this time, the color will easily fade.
