What to Look For
Dry hair is caused by a lack of moisture in the hair, and lack of moisture is caused by damage from heat, styling and environmental influences. To restore moisture to your hair, you need to choose a shampoo that both moisturizes and cleanses the scalp without removing the natural oils. To do this, you want to avoid harsh cleansers and chemicals like Sodium Lauryl Sulfate, Ammonium Lauryl Sulfate, Ammonium Laureth Sulfate, Ammonium Xylene Sulfonate, TEA Lauryl Sulfate, Magnesium Sulfate, Sodium Thiosulfate, Sodium C14-16, Olefin Sulfonate, Alkyl Sodium Sulfate, Alkyl Benzene Sulfonate , TEA-Dodecylbenzene, Sodium C12-15 Alkyl Sulfate and Sodium Dodecyl Sulfonate.
