Sulfates have some useful purposes. When added to soaps, cleansers, and shampoos, they enhance the product's cleaning ability as well as produce lots of fluffy suds. However, sulfates in shampoos can irritate the skin and dry out hair. Fortunately, sulfate-free shampoos that are both effective and affordable are widely available from drugstore brands. They are ideal for consumers who are prone to scalp dryness and irritation as well as anyone with color-treated hair. Think about your hair type before you buy. Different sulfate-free formulas are available with ingredients that tackle various hair and scalp concerns. Most drugstore sulfate-free shampoos are made to use with matching conditioners. For added value, look for a set of sulfate-free shampoo and conditioner.
