Sodium lauryl sulfate (SLS) is a common ingredient in shampoos and other personal care products that works as a surfactant to trap oil and dirt in hair so it can be rinsed away with water. However, some people prefer to use sulfate-free shampoos, which use gentler, plant-derived surfactants such as amino acids and seed oils. Sulfate-free shampoos are generally considered to be better for the hair and scalp, as sulfates can strip away natural oils and cause irritation. When looking for a sulfate-free shampoo, it is important to read the ingredient labels carefully to avoid products that contain sulfates or other harsh chemicals. Some examples of sulfate-free shampoos include:

• Faith in Nature Aloe Vera Shampoo
• Redken Frizz Dismiss Shampoo
• AG Colour Savour Shampoo
• Pravana The Perfect Blonde Shampoo
• Pureology Strength Cure Shampoo
• Nevo Moisture Rich Shampoo
• Deva Curl Low-Poo Shampoo
• AG Hair Curl Revive Sulfate-Free Hydrating Shampoo
