What’s in Your Shampoo? April 14, 2009

Ever shampoo your hair and then get a skin rash or hives? How about pimples, dry scalp, dandruff or contact dermatitis? Maybe you’re allergic to the chemicals in your shampoo. In addition to an allergic reaction, you may be exposing yourself, unnecessarily, to chemicals that can do far more damage.

Preservatives (Parabens)

One of the most common cause of negative reactions are the preservatives used to protect against product contamination and bacterial growth. In addition to allergic reactions, parabens can disrupt the hormone (endocrine) system and were found in the breast cancer tumors of 19 of 20 women studied. The Centers for Disease Control (CDC) tested urine from 100 adults and found parabens in nearly all.  (Environmental Working Group – Parabens)

While the U.S. Food and Drug Administration continues to believe that at the present time there is no reason for consumers to be concerned about the use of cosmetics containing parabens, they in fact, do NOT regulate parabens in cosmetics. In the meantime, the U.S. Environmental Protection Agency recently funded a case study on the toxicity of parabens in wastewater to fish. Considering the FDA’s glorious record in safeguarding our food supply, I’m not convinced they’re guarding our best interests as far as the cosmetics industry is concerned.

Parabens can be listed as:

  • benzylparaben
  • butylparaben
  • ethylparaben
  • isobutylparaben
  • isopropylparaben
  • methylparaben
  • parabens
  • propylparaben
  • sodium methylparaben
  • sodium propylparaben

Organic products may use the natural form of preservatives such as citric acid or a derivative.

For more information, see Healthy Child, Healthy World – Use Precaution with Parabens.

Sodium Lauryl Sulfate

One of the most common ingredients in shampoo is a common detergent: sodium lauryl sulfate (SLS). SLS is used in shampoo because it strips out oils and, despite its name, has a low sodium content. However, SLS can cause contact dermatitis by irritating the skin. Some companies have tried to link SLS and cancer but TreeHugger did their own research in this article: Common Eco-Myth: Sodium Lauryl Sulfate (SLS) Causes Cancer. So, while, you can dry your hair and scalp to a fare-thee-well, there is no hard evidence linking SLS to cancer. Depending on how greasy your hair is, choose your surfactant accordingly.

Gentle Surfactants

This list of surfactants are gentle but don’t cleanse as well.

  • cocamidopropyl betaine
  • cocamphocarboxyglycinate-propionate
  • sodium lauraminodipropionate
  • disodium monococamido sulfosuccinate
  • disodium cocamphodipropionate
  • disodium capryloamhodiacetate
  • cocoyl sarcosine
  • sodium lauryl sarcosinate

Harsh Surfactants

The following list could cause an irritated scalp or be drying to hair.

  • sodium lauryl sulfate
  • TEA-lauryl sulfate
  • sodium C14-16 olefin sulfonate
  • TEA-dodecylbenzene

Diethanolamine

Diethanolamine, more commonly called DEA, is not only a suspected carcinogen, it has been shown to negatively affect the development of memory cells, making it a particularly dangerous ingredient for pregnant women to use. One of its derivatives, triethanolamine (TEA) has also been shown to be carcinogenic.

Diethanolamine appears as:

  • Cocamide DEA
  • Cocamide MEA
  • DEA-Cetyl Phosphate
  • DEA Oleth-3 Phosphate
  • Lauramide DEA
  • Linoleamide MEA
  • Myristamide DEA
  • Oleamide DEA
  • Stearamide MEA
  • TEA-Lauryl Sulfate
  • Triethanolamine

Methylisothiazoline

Methylisothiazoline, or MIT, limits the potential for microbial contamination in water based solutions. It has been shown to cause neurological damage, potentially putting a fetus at risk for brain damage. The chemical might also be a factor in the development of Alzheimer’s and other nervous system disorders.

For more information see Medical News Today: Shampoos with Methylisothiazoline May Pose Risk for Unborn Babies.

Fragrance

Most hair care products have some form of added fragrance. Fragrance is considered a trade secret and does not have to be revealed. Fragrances are considered to be among the top five known allergens and are known to both cause and trigger asthma attacks. All I have to do is walk by a perfume counter to trigger a reaction.

Natural Shampoos

You can find “organic” or “natural shampoos” on the market. Bypass the marketing on the label and go straight to the list of ingredients to make sure you’re getting a product without synthetic chemicals. They are likely to be more expensive than the drugstore brands that contain potentially harmful chemicals. However, what many people don’t know is that you don’t have to wash your hair more than once or twice a week. In fact, it’s healthier for your hair to wash it less frequently, as it gives the natural oils (which is what really creates shine) a chance to replenish themselves. I know, I know. When I was much younger, I washed and dried my hair every day thinking I needed to. These days, I usually skip the shampoo and wash my hair with conditioner. Then I let my hair dry naturally. My hair has never been in better shape.

If you have dandruff, give yourself a natural hot oil or deep conditioning treatment, which is far better for your scalp than dandruff shampoos.

You can also make your own shampoo:

  1. [...] I can hardly remember that girl. I would never spend that much time on my hair these days, nor would I ever use all those products, now that I know that they’re filled with toxins. Have you read your shampoo label, lately? Pretty scary, huh? I won’t rehash all the info on toxic beauty products. You can read about them in various books (like Gorgeously Green), or blogs (check out Eco Yogini here, and a great post by Verda Vivo here). [...]

  2. Interesting post, and a very interesting blog… I am subscribed :-)

    Thanks, Darshan and No-poo hair for your comments. The ingredients in shampoo reads like a chemist’s lab. Plus, if you shampoo and rinse your hair in the shower, all the ingredients come into contact with the rest of your skin. ~ Daryl

    I really enjoyed the article posted regarding harmful ingredients in personal care products. It was very informative, and I believe you are absolutely correct about the negative impact that these chemicals can have on our bodies. I have discovered several amazing reports to validate your position, and I think you would find the information fascinating. I would love to discuss this further with you. Please email me at your earliest convenience at tdeann24@gmail.com. One report in particular is very serious in nature and was documented on CNN. I’ll send you a link.

  5. Thanks for the shoutout! Glad you enjoyed my post.

  6. I’ve heard that shampooing your hair shouldn’t be done more than once a week. I’ve stuck to that and its been fine. I will shampoo though every time I leave the gym.

  7. I have started losing my hair, so I am now using herbal shampoos, I hope they are fine.

  9. Shampoo Samples Says:

    Nice post.Well i switched to herbal shampoos a while ago and the result was amazing!

  10. Clarisa Says:

    This is why I switched over to using only organic skin care and hair care. These synthetic chemicals are scary and because they have been linked to causing health problems, I think they should be banned.

  11. Angel Says:

    Good post, all those ingredients I try and avoid and use use organic natural shampoos. Its so good what you learn when going natural.
