One of the most common causes of hair loss is an ingredient found in many shampoos: sodium lauryl sulfate (SLS). SLS is a detergent and surfactant that helps to create a lather when using shampoo, but it can be abrasive and damaging to the scalp and hair. When used in excess, it can strip away the natural oils and proteins that are essential for healthy hair growth. It can also lead to scalp irritation, which can further contribute to hair loss.
In addition, over-drying the scalp and hair can result from using shampoos containing SLS. This can lead to excessive shedding of hair, as the scalp is not able to retain moisture, leading to breakage and thinning of the hair.
In order to minimize the effects of SLS on hair, it is important to use a shampoo that contains other more gentle ingredients that can help nourish the scalp and hair. Look for shampoos that contain natural oils such as coconut oil, olive oil, or jojoba oil, as well as proteins and vitamins that can help strengthen the hair. Also, be sure to not over wash your hair, as this can lead to dryness and breakage.
