Sulfate-free shampoo is a type of hair cleanser that does not contain sulfates, which are harsh detergents commonly found in many traditional shampoos. These sulfates can strip natural oils from the hair and scalp, leading to dryness and irritation. By using sulfate-free options, you can maintain your hair's natural moisture and keep it healthy and shiny. Many people, especially those with curly hair or color-treated hair, prefer sulfate-free shampoos because they are gentler and less likely to cause damage. These shampoos often use natural ingredients to create a rich lather, making them a popular choice for anyone looking to care for their hair without harsh chemicals.
