Shampoos contain some ingredients that have the potential risk of causing hair loss and affecting health. By-products that are normally formed during the production of shampoo do not appear on the ingredients list. These by-products can produce toxins that damage the liver and kidneys if they are potential carcinogens or neuroleptics. In fact, the ingredients listed always include Sodium Laureth sulfate, a potential carcinogen that causes hair loss and eye irritation. In addition, there are shampoo ingredients that can react chemically with other products and form potentially harmful substances.
Carcinogenic by-products
Formaldehyde and 1,4-dioxane are two potentially harmful substances in shampoos that will never be listed on the ingredients list. As a by-product of the product, they are not required to be listed on the label and the EPA has listed formaldehyde as a probable human carcinogen.
Reports have claimed that high levels of inhalation or dermal exposure to high concentrations of 1,4-dioxane can cause fatal neurological symptoms because the chemical depresses the central nervous system.
In addition, studies have found that exposure to 1,4-dioxane has toxic effects on the liver and kidneys in humans and animals.
Nonetheless, the Skin Care Products Association report claims that the concentrations of chemicals in shampoos are low and therefore can be considered safe. In conclusion, there is no definitive data on these by-products.
Sodium Laureth Sulfate
Sodium Laureth sulfate and its closely related chemicals have been suspected to be potential carcinogens and have the potential to cause hair loss.
Skincare experts recommend avoiding the use of shampoos that contain sodium lauryl sulfate, ammonium lauryl sulfate, ammonium laureth sulfate, ammonium xylene sulfonate. If you are using an anti-dandruff shampoo, it is best to avoid sulfur yellow and selenium sulfide.
Diethanolamine and Triethanolamine
Diethanolamine and Triethanolamine are used in shampoos as solvents, emulsifiers, and shampoo wetting agents. However, according to the National Toxicology Program, topical Diethanolamine and Triethanolamine have been found to be associated with cancer in laboratory animals.
Nitrate is the preservative component of shampoo. Diethanolamine and Triethanolamine react with the nitrates in shampoo to form carcinogenic factors.
