How often should I dye my hair?

Depending on the length of your roots, it is recommended to color / dye your hair every 3 to 4 weeks. Moreover, the difference between your natural color and the color-treated hair also has an incidence on the frequency in which you should color your hair. For example, if a client has white or grey hair and applies a very dark color on top, the roots will be very visible in a shorter time frame than if the client opted for a light blonde color.
