This sulfate free shampoo is suitable for colored hair, which is also suitable for people who have sensitive skin and hair. If you have dyed your hair, this shampoo is for you. Sulfate in some detergents eventually changes the color of the hair, which also reduces its shelf life. The best way to solve these problems is to leave out sulfate-containing shampoos and use free sulfate shampoo, which will stabilize the hair color and increase its durability.
