Health n Fitness: Side effects of chemicals in shampoos. The first thing to mention is that many chemicals contained in shampoos can strip the natural oils from the hair. This can cause hair to become damaged by impurities, looking lifeless and becoming dry and brittle which leads to split ends and breakage.
Secondly, some chemicals included in shampoos do leave hair looking fabulous but can also actually cause irritation to the scalp. This can lead to itching, dryness and flaking which appears as dandruff. In some cases on sensitive scalps, it can even cause an allergic reaction such as welts forming and hair loss.
It is important to remember that the skin is porous, so anything applied to it, even if it was intended for the hair, will penetrate the skin and be absorbed into the body. Most chemicals are recognised as toxins by the body and are not naturally absorbed into the body.
