The trouble with shampoo is that our hair and skin is not build to handle the pollutants most people get in contact with throughout the day.

Soap and shampoo may not have been necessary in the past, but they are now because water alone and even some natural remedies that would otherwise be preferable, can’t reliable wash that gunk of your skin/hair

There’s so many bad stuff in a lot of cosmetics, but sadly we do need soaps to wash off some of the other bad stuff from outside.
