Check your shampoo labels and look for Sodium Lauryl Sulfate (SLS) – a common foaming agent that present in 90% of commercially available shampoos. SLS is able to permeate the skin effectively and concentrate in some organs such as eyes, brain and heart. SLS washes away the hair's moisture and may lead to the premature shedding of hair, clogging hair follicles and hair loss. Therefore, it is important to avoid products containing SLS. Instead seek natural alternatives! AFC Shokaigan Shampoo do not contain SLS but incorporates a natural blend of 10 amino acids to gently but deeply cleanse, unclog hair follicles and regulate scalp pH levels.
