The child can dye their hair from the age of ten, but the painting must be done in a hairdressing salon and with the use of a paint suitable for the child, without ammonia and without hydrogen peroxide, such as Wellaton toning shampoos or from Biotom, for example.
These products do not harm the scalp and are less harmful to the hair. But care must be taken to moisturize the hair weekly, as they will be easier to stay dry and brittle.
The later the girl leaves to put any type of chemical in her hair, the later she will need treatments to soften, shine and reduce the volume. At this stage the child may also stop using infant hair products and may use those for adults, which contain specific ingredients for damaged hair.
