ONLY sure-fire way to gather information about the ingredients contained in your hair care products so you can make smart purchasing decisions. This information can also be useful in helping you determine which styling aids to purchase and to understand why certain products are heavy, greasy, or drying to your hair. Companies may (sometimes intentionally) choose to make product packaging confusing. But we as consumers must do our homework. So take a deep breath, get out your magnifying glass, and let’s tackle the ingredient list together. The Bad Guys: Ingredients to Avoid If you have a strong preference for using natural products, here are ten ingredients to steer clear of the next time you go shopping for “natural” hair products: 1. Sodium Lauryl/Laureth Sulfate (SLS) — is a detergent used in most shampoos, shaving creams, and bubble baths for its cleansing and foaming properties. Like most harsh detergents found in your shampoo, SLS strips the hair of its natural oils — often leaving it dry and brittle. SLS may also cause eye irritation, scalp scurf similar to dandruff, skin rashes, and other allergic reactions. Be on the lookout for the words “comes from coconut.” SLS is frequently present in pseudo-natural products under this description. Although there are many websites claiming SLS is a carcinogen, the American Cancer Society has taken the position that SLS and Sodium Laureth Sulfate (SLES) do not cause cancer. 2. Diethanolamine (DEA), Triethanolamine (TEA) — These ingredients are used to stabalize the pH of most personal care products. Depending on the individual, DEA and TEA may cause allergic reactions and eye irritation, as well as dry hair and skin. Neither DEA nor TEA is carcinogenic. However, if either of these compounds interact with nitrites – often present as contaminants in personal care products, a chemical reaction may result, which can lead to the creation of cancer-causing nitrosamines. In recent years, many companies that sell “natural products” have been caught using DEA and TEA in their cosmetic preparations. 3. Parabens (Methyl, Propyl, Butyl and Ethyl) — Parabens are the most commonly used preservative in shampoos, conditioners, and other styling products. The antimicrobial properties of these chemicals help to extend the shelf life of most cosmetics and personal care products by two to three years. Parabens have long been considered safe — but a few recent studies have suggested that these chemicals may actually lead to breast cancer. The validity of these studies have been challenged due to the lack of experimental evidence, but such alarming claims continue to be the subject of further investigation. 4. Diazolidinyl Urea, Imidazolidinyl Urea — After parabens, ureas are the most commonly used preservative in cosmetics and personal care products. Under certain circumstances, exposure to ureas may cause contact dermatitis. 5. Lanolin, Petroleum and Mineral Oil — These cheap ingredients are widely used in greases and pomades formulated for black hair and offer no real moisturizing benefits. In fact, these ingredients often weigh the hair down and prevent the natural oils produced by the scalp from being absorbed by the hair shaft. For a natural alternative, try jojoba, coconut, or sweet almond oils for their conditioning properties. 6. Propylene Glycol — This humectant is commonly found in shampoos, lotions, after-shave, deodorants, mouthwashes, and toothpastes to give a product “glide” or “slip.” This chemical is also an active ingredient in anti-freeze, airplane de-icer and brake and hydraulic fluid. Recent findings indicate that propylene glycol may cause allergic reactions, dermatitis, dry skin, hives, and eczema. Because it is easily absorbed by the skin, the Environmental Protection Agency has issued a mandate requiring workers to wear protective gloves, clothing, and goggles when handling this toxic substance.[i] Material Safety Data Sheets also warn against skin contact with this agent because it has been shown to cause brain, liver, and kidney abnormalities. Beware of PEG (polyethylene glycol) or PPG (polypropylene glycol)—they are related synthetics. 7. Synthetic Colors — Artificial colors are used widely in hair care products for aesthetic purposes. These ingredients frequently appear as FD&C or D&C followed by a color and a number (e.g. FD&C Red No. 6 / D&C Green No. 6). Color pigments may cause skin sensitivity and irritation. The safety of these ingredients is also questionable — because they are derived primarily from coal tar, a known carcinogen. 8. Synthetic Fragrances — Synthetic fragrances are present in most shampoos, conditioners, and styling pomades. The word “fragrance” can indicate the presence of up to 4,000 separate ingredients, many of which are synthetic.[ii] In some individuals, these compounds can induce headaches, dizziness, rash, skin discoloration, violent coughing, vomiting, and skin irritation. For a safe alternative, try purchasing unscented products from your local Whole Foods Supermarket and adding your own fragrance using all-natural essential oils. 9. Formaldehyde — This cheap preservative is used in hair care products containing water to prevent the growth of bacteria. Formaldehyde is a suspected carcinogen and may cause skin reactions, trigger heart palpitations, or lead to joint pain, allergies, headaches, chest pains, ear infections, and dizziness. Despite its possible harmful side effects, cosmetic manufacturers are free to use formaldehyde in your shampoos, conditioners and lotions without listing it as an ingredient. 10. Coal Tar — Many shampoos designed to treat dandruff contain coal tar — although it’s frequently absent from the product’s list of ingredients. Protect yourself and be on the look out for this compound, which is disguised in many forms (e.g. “Stantar”, “Clinitar”, “Medi-Tar” and “Polytar”). While the FDA acknowledges that coal tar is a carcinogen under certain conditions, it has taken the position that it still safe for use as an active ingredient in most over-the-counter dandruff shampoos. Not surprisingly, most shampoo manufacturers are in agreement and continue to use it. Still, in addition to being a cancer hazard, coal tar has been found to cause allergic reactions, asthma attacks, headaches, nausea, fatigue, nervousness, and lack of concentration. Manufacturers often make the argument that these and other synthetic ingredients pose no real, serious threat to our health and safety since they are present in personal care products in such small amounts. Even if this were true, it is hard to believe that these chemicals will not have some long-term effect on our bodies after we’ve been exposed to them day after day, year after year. If you frequently suffer from any of the symptoms described above, you may want to check the list of ingredients on your hair and skin care products. If you have children or sensitive skin, you should also be mindful that chemical additives and synthetic ingredients can sometimes cause allergic reactions even in small doses. Your best bet for protecting yourself and your family is to avoid products containing high concentrations of synthetic ingredients and to look for natural alternatives whenever possible. I know this may seem like a lot to know, but a simple rule of thumb is that if you can’t pronounce/don’t understand the first five to seven ingredients don’t buy it.
