How Long to Leave Hydrogen Peroxide on Hair
There is a way to dye hair in the world, and hydrogen peroxide is often used. However, when hydrogen peroxide is placed in the hair, it is really related to the effect of hair dyeing and the damage to the hair.
If you want a light and even color, and the hair care is not damaged, you need to be careful about the duration. For those who first dye or have rough hair, you can leave it for twenty to thirty minutes. However, if the hair is soft or has been dyed, the duration should be reduced, about fifteen to twenty minutes is enough.
If it takes too long, although the color is easy to show, the damage to the hair will be strong, causing dry and rough, and losing its softness. If the time is short, the color is not satisfactory, and it is difficult to achieve people's wishes.
Therefore, when using hydrogen peroxide for hair dyeing, the quality of hair and past dyeing conditions must be carefully reviewed to determine the appropriate duration in order to obtain a pleasing color and maintain the health of hair.
