Autoradiographic studies of rat skin treated with radiolabelled Sodium Lauryl Sulfate found heavy deposition of the detergent on the skin surface and in the hair follicles;
damage to the hair follicle could result from such deposition. Further, it has been reported that 1 percent and 5 percent Sodium Lauryl Sulfate produced significant number of comedones when applied to the pinna of albino rabbits. These two problems -
possible hair loss and comedone formation - along with proven irritancy, should be considered in the formulation of cosmetic products.

SLS denatures proteins, which causes skin and *eye damage. It also can react
with nitrogen bearing molecules to form carcinogenic nitrates. If SLS is combined
with a long chain alcohol molecule (called ethoxylation) to create higher foam
levels; it becomes known as SLES (Sodium Lauryl Ether Sulfate or Sodium Laureth
Sulfate) SLES can reacts with ingredients to form both carcinogenic nitrates and
the even more potentially dangerous carcinogenic dioxin.
Tests in Germany have
shown that SLES can cause hair loss
