When a product is labeled as "sulfate-free," it indicates that it does not contain sulfates, which are surfactants commonly found in many personal care products. Sulfates, such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), are known for their ability to create lather and remove dirt and oil. However, they can also strip the hair of its natural oils, leading to dryness, frizz, and potential damage, especially in people with sensitive skin or those who have dry or color-treated hair. By using a sulfate-free product, consumers can maintain the moisture balance of their hair and scalp while still effectively cleansing.

While sulfate-free products might sometimes be aimed at individuals with colored hair or those seeking more natural alternatives, the term "sulfate-free" specifically focuses on the absence of sulfates and their stripping effect on hair rather than indicating a complete absence of all chemicals or being biodegradable.
