What is sulphate-free shampoo?
A sulphate-free shampoo is a type of shampoo that does not contain Sodium Lauryl Sulphate (SLS), a chemical commonly used in industrial cleaning products. SLS can irritate the scalp, strip natural oils, and dry out hair.
Sulphate-free shampoos are gentler on the scalp, making them ideal for individuals with sensitive skin or sulphate allergies. Many users find that sulphate-free shampoos leave their hair smoother and less dry.
