The following article (edited) on shampoo toxins and cancer causing agents appeared in the health journal, "Doctor's Prescription ForHealthy Living," and was written by Dr. L. Stephen Coles, M.D., Ph.D. The editorial board of this journal consists of six medical doctors: Cynthis Loes, Megan Shields, Carl Boggs, L. Stephen Coles, Roger Libby,Michael Loes, and Gary Wikholm.
Almost every shampoo sold in drug or department stores contains undisclosed contaminants or carcinogen precursors. The safest brands today are in health food stores.
There is no getting around it: Humans are plagued and blessed and everything in between by their hair, says natural beauty author Margaret Dinsdale in her book Skin Deep (Camden House, 1994). Our society places great emphasis on hair, as an evening's worth of television commercials will quickly reveal. Is it the right style? Is it the right colour? Is it shiny enough? Is it clean enough? Is it wavy enough? Is it straight enough? It sometimes seems as though our success in the world may rise or fall on how we manage our hair and scalps.
No matter how enticingly packaged or hyped with advertising, if your shampoo uses unsafe ingredients, the product is likely to be hazardous to your health, especially over the long run.
Unsafe ingredients in shampoos make people with sensitive skin, including babies and children, vulnerable to allergies and irritation. More ominously, many drug store brands contain carcinogens not disclosed on labels which present a cumulative or long-term cancer risk to consumers.
When you shampoo, your scalp is exposed to warm water and detergent, making the skin a permeable pathway for absorption of toxins. To compound the problem, the powerful detergents in most shampoos emulsify oil, removing this protective layer from the hair and scalp. This toxicity hazard is especially acute for babies and children whose immune systems are not fully mature.
There are safe and healthy (shampoo) alternatives, however... These shampoos combine herbs and nutrients with mild cleansers that leave your hair looking great without exposing you or your loved ones to carcinogens or carcinogen precursors.
Some shampoo-related health problems are immediate such as allergies and irritation, while others are delayed. Let's look a little more closely at each of these types of health hazards. Armed with good information, we should be able to avoid the worst allergens and irritants, as well as carcinogens.
Conventional shampoos contain synthetic fragrances and a wide range of preservatives. Both have been shown to be the leading causes of cosmetic-related allergies and irritation today. Synthetic fragrances are often made from more than 600 separate chemicals, many classified as extremely hazardous, but not required to be listed individually on the label or provided separately to consumers who request such information. Fragrances are the number one cause of allergies and irritation in cosmetics and personal care products.
Natural fragrance or none at all is a safe and healthy choice if you find that your shampoo is bothering your eyes, skin or scalp. Another class of allergens and irritants in shampoos are those preservatives that contain, release, or break down into (dangerous) formaldehyde, including:
Diazolidinyl urea Imidazolidinyl urea 2-bromo-2-nitropropane-1,3-diol (Bronopol) Quaternium-15
Two other common ingredients, polyethylene glycol (PEG) and DMDM hydantoin, also degrade (in products during storage) into formaldehyde. Polyethylene glycol may be shown on the label attached to other ingredients or with a number, as in PEG-150 distearate.
Among other miscellaneous ingredients likely to be eye, skin, or mucous membrane irritants are:
EDTA (ethylenediamine tetraacetic acid) D&C Green 5 Selenium sulfide (used in anti-dandruff shampoos)
Many popular shampoo brands contain carcinogen precursors. The two main culprits are diethanolamine (DEA) and triethanolamine (TEA), often shown on labels attached to other compounds as in cocamide-DEA or TEA-sodium lauryl sulfate. These ingredients are not carcinogenic themselves but combine with nitrites (added to raw materials or present as contaminants) to form cancer-causing nitrosamines. We recommend avoiding products with DEA or TEA.
The preservative 2-bromo-2-nitropropane-1,3-diol can also cause nitrosamine formation. Vitamins A,C, or E will slow formation of nitrosamines to an extent, but it is better to seek products without carcinogen precursors at all.
Artificial colors are disclosed on product labels. Almost all have some evidence of carcinogenicity or are contaminated with cancer-causing impurities such as arsenic and lead. Eliminate these from your shampoo if you want a safe and natural product.
Some shampoos may be contaminated with 1,4-dioxane, which is carcinogenic. This contaminant is not disclosed on product labels. The best way to protect yourself from this carcinogen is to recognize those ingredients most likely to be contaminated with 1,4-dioxane. These include ingredients with PEG, polyethylene, polyethylene glycol, polyoxyethylene, "eth" (as in sodium laureth sulfate), or oxynol in their names. Both polysorbate 60 and polysorbate 80 may be contaminated with 1,4-dioxane.
For people who are seeking truly safe and natural healing pathways, their choice of shampoo and other cosmetic products is extremely important. Virtually all of the best cosmetic brands, however, can be found only at health food stores. There are many healthy product lines. (One such line is Aubrey Organics.) (Look for ...hair products created without any synthetic chemicals, no synthetic fragrance, formaldehyde donors, or nitrosamine precursors. Also look for no animal testing or animal products. Look for vegetarian soaps and proteins including coconut oil, corn oil, olive oil castile, wheat and soya protein. Look for use of deionized water, or preservatives such as antioxidant vitamins A, C, E and citrus seed extract, all of which also help fight premature skin aging. Look for natural fragrances such as geranium, lavender, orange blossom and jasmine oils.) Some product lines use wild-crafted or organically grown plants for their conditioning properties. (Look for) ...herbal extracts that contain propylene glycol, a potent allergen commonly used as a carrying agent in place of vegetable glycerine (which is more expensive). Look for product lines that are made fresh daily so they don't sit on the shelf (although they will last more than a year). Plus, look for lines that don't use distributors or warehouses. The better products are delivered directly to health food stores, which guarantees their freshness.
