Check your shampoo label and look for Sodium Lauryl Sulfate (SLS) – a common foaming agent that present in 90% commercially available shampoos. SLS is able to permeate the skin effectively and concentrate in some organs such as eyes, brain and heart. It washes away the hair moisture and may lead to premature shedding of hair, clogged hair follicle and finally, and hair loss. Avoid products containing SLS. Seek natural alternatives!
