Sodium Chloride In Shampoo Sodium Chloride In Shampoo?? Why?

Sodium chloride in shampoo?? why? - sodium chloride in shampoo

I've heard that most of the shampoo is a drug called "salt", and it seems that the sodium chloride fade in color .. It helps, therefore, a brand called Davines .. who reported that their products are not sodium chloride in their hair wash Eng .. I wonder what to do to replace sodium chloride?

Why use any other manufacturer of sodium chloride, although only helps color fade do anything?

complicated, but thanks for the reply .. appreciated ..
