Over the past ten years, I have tried countless brands of shampoo. I used to be happy with a bunch of different brands, until I did some research and learned about some nasty chemicals found in the vast majority of products on the shelves.
1.
Sodium Laureth Sulphate- You've likely heard of it by now. It is used as a foaming agent, so is found in many face washes, soaps, shampoos, dish detergents, bubble bath, etc. It may be contaminated with ingredients that are known/ possible human carcinogens, harm the nervous system, interfere with human development, and on top of all that, if the SLS hasn't been 'vaccuum stripped' to remove a certain chemical, it doesn't break down in the environment for a long time. It is also a known irritant of the skin and eyes.
2.
Sulphates- You've definitely heard of this one. It's used as a preservative in cosmetics, and is the most widely used of all preservatives. Sulphates interfere with hormone function, and have been detected in breast cancer tissues, associating them with cancer. Studies also show that it can react with UVB, causing increased skin aging and DNA damage (so much for that anti-aging cream!). Sulphates are also commonly used as an ingredient in fragrances, but you'll never know, because fragrances do not have to list their ingredients as they are 'trade secrets'.
3.
Fragrance- fragrances are considered 'trade secrets', and so manufacturers aren't required to list the ingredients. Fragrances are cocktails of chemicals, containing as much as 3000 ingredients. Even products that are labeled 'fragrance-free' may still have fragrance, with a masking agent that tricks your brain into not detecting the scent.
Phthalates, used as an ingredient to make scent linger, has been linked to early puberty in girls, reduced sperm count in men, reproductive defects in the male fetus, obesity and insulin resistance. It may also cause liver and kidney damage in children if ingested for extended periods. Oh, and it is toxic to wildlife and the environment.
The list goes on, I'm afraid. If you want to know more, please read

So let's be frank. If you have ever tried a shampoo without SLS (the foaming agent), you may have been surprised by the results. I have tried brand after brand of alternative shampoos and conditioners. I find my hair (which is past shoulder length) gets really tangled. It's also (currently,where I live) hard to find an alternative brand. If you go into the grocery store, you may not have a SLS or sulphate free option. +The Great Canadian Superstore has a good selection, and so does +Food Stuffs, a local natural and organic food store.
If you are looking for a product without certain ingredients, my advice to you would be to trust only the ingredients label. Words like "natural", "organic", "eco-friendly", "safe", are all terms used by marketers to sell a product. Look on the ingredients label, yes it takes a minute, and a good bit of practice to get used to all the words you are looking for, but it's the only way to know what is in a product.
