Many Aussie shampoo products contain sulfates, however, they do offer sulfate-free solutions also. It's important to read the ingredients to ensure that you're buying a product without sulfates. Keep in mind that if your skin is sensitive or your hair is dry, it may be good to use a sulfate-free shampoo instead of the usual shampoo with sulfates. Sulfate-free shampoos use alternative cleaners to help make your hair softer and better conditioned. This is great for people with curly hair because there is traditionally less moisture in curly hair strands. These alternative cleansers also have gentler formulas to mitigate skin irritation and keep your hair silky smooth.
