Sulfates in shampoos produce a foamy lather that eliminates debris, oil, and styling product accumulation from the hair and scalp. As a consequence, the hair feels light and fresh. Sodium lauryl sulfate is one of the most frequent sulfates found in cosmetics (SLS). It's also one of the most irritating. The other common sulfate used in shampoos is sodium laureth sulfate (SLES). Like SLS, SLES is a surfactant that cleans by breaking down surface tension and removing soil from hair and skin. It works well on tough environmental stains such as grass and oil-based products like peanut butter. However, it can be harsh on the skin if not used properly. People who suffer from sensitive skin types may want to avoid products with sulfates since they can cause problems for those with oily or blemish-prone skin. Additionally, sulfates are known to strip hair of its natural moisture, causing hair to appear dry and brittle. Many popular shampoos contain some level of sulfate due to their cleansing abilities and foam production. But excessive use of shampoos that contain sulfates can lead to hair loss and irritation. If you're looking to cleanse your hair without using many chemicals, consider trying a vinegar rinse instead. Vinegar has been used for centuries around the world for its beauty benefits. It removes dirt, oils, and bacteria from hair without drying it out.
