- Sodium Lauryl Sulfate (SLS)
This sulfate produces a lathering foam that some people enjoy, but when left on the scalp, it can damage follicles and has other toxic effects on the human body. Oh no! SLS should be avoided by anyone with color-treated or dry hair, as it can fade your color and strip your strands of natural oils.
Parabens are also known to be carcinogenic. They are used as a preservative in cosmetics and shampoos to prevent bacteria from growing. Parabens have been linked to increased growth of breast cancer cells due to their ability to mimic the hormone estrogen.
- Diethanolamine (DEA) and Triethanolamine (TEA)
DEA and TEA are also emulsifiers and foam agents, which reduce surface tension and allow water-soluble and oil-soluble ingredients to mix. The European Commission has prohibited the use of DEA in cosmetics.
Formaldehyde is a known human carcinogen that has been shown in animal studies to be absorbed through the skin. Manufacturers frequently add it directly to products as a preservative, but it can also be released over time via a chemical process from other types of preservatives. Quaternium-15 is a common one in shampoos. They are also present in chemicals. Brazilian blowouts are available at hair salons.
Most alcohols have a drying effect, and the higher they appear on the ingredients list, the more alcohols are present in the product. Some alcohols that are better for dry hair start with a “C” or a “S,” such as Cetearyl alcohol and Stearyl alcohol. They can actually aid in the retention of moisture in your hair. Isopropyl alcohol or propanol are usually the ones to avoid if you already have dry hair.
- Synthetic Fragrances
Products labeled “fragrance” may contain thousands of hidden chemicals. Some fragranced cosmetic products contain ingredients that can disrupt the reproductive system and cause cancer or asthma. They can also irritate the skin and scalp, resulting in hair loss.
- Synthetic Colors
To make shampoos and conditioners look nice, they are usually dyed with a synthetic color. These colors are derived from petroleum or coal tar, both of which have negative health effects. Synthetic colors are typically identified by the letters FD&C or D&C followed by a number.
Dimethicone is a type of silicone that is found in many hair products and contributes to product buildup, which causes your hair to feel greasy. It acts as a protective layer on the surface of the hair, preventing moisture and nutrients from entering and instead collecting dirt and residue. It has the potential to clog the pores on the scalp and cause skin irritation.
Triclosan was banned in antibacterial soaps in 2016, but it is still permitted in toothpaste, shampoos, and deodorants. It is a chemical antibacterial agent that has been linked to hormone disruptions, which can lead to cancer and have an impact on fetal development, among other things.
- Retinyl Palmitate
Retinyl palmitate is a retinol ester that has been combined with palmitic acid. It is a known skin irritant, causing peeling, scaling, redness, and itching. Cancer, reproductive issues, and organ toxicity are all possible side effects of retinyl palmitate.
Harmless Shampoo Ingredients
While there are many harmful shampoo ingredients and shampoo brands, many shampoos use natural, non-toxic, and organic ingredients, and you can even make your own homemade hair treatments using ingredients from your own kitchen. If you are experiencing hair loss or unhealthy hair growth and suspect that chemicals such as those listed above are to blame, consider switching to a natural alternative.
