Can I nuance with shampoo or just with shades?

It is also possible to nuance with shampoos or treatments. Salon In has its Color Intensifier collection that helps tone down some unwanted reflections. The collection has a platinum tone, beige pearl, violet and black. But it must be taken into account that, if this type of product is used very frequently, it can saturate the hair and interfere with the result of the next colouring, therefore, it should be used when the hair really requires it.
