Gray or white hair tends to appear yellowish over time, due to the incidence of UV rays and other external factors that oxidize the threads, changing the color. If you are starting to leave the white strands now, probably the greatest concentration is at the root of the hair.
If you feel that they are already yellow, use alternate between your usual shampoo and Shampoo Matizador, because the other products of the line for blond or gray hair are not indicated for application in the root. The Shampoo Matizador helps to polish the hair fiber and has anti-yellowing and anti-fading action. The frequency of use depends on the level of yellowing. For gray hair, the recommended is one to three times a week. For whiter hair, it is recommended to use it only once a week.
