Shampoos might be doing your hair more harm than good for a few reasons, but the usual suspect is sulphates. They give you that foaming and frothing when washing your hair but can be detrimental to the hair itself. Sulphates strip hair of its natural oils leaving it at risk of breaking. So if you’re seeing lots of hair breakage or hair loss when brushing it might be time to switch to a sulphate-free shampoo.
