Regular shampoos are sometimes too harsh on hair, leaving it feeling damaged. Mild shampoos use nonionic surfactants and amphoteric surfactants, the mildest forms of detergents, and are most often found in baby shampoos. Mild shampoos are most suitable for children and people who have low oil production or who are not usually exposed to dusty or dirty environments.
