The perky woman on this Grist video ("Umbra") has convinced me to make my own shampoo and conditioner. Not only will this save me money, but it will put end my practice of covering my scalp with numerous chemicals that contain known-harmful ingredients--many shampoos and conditions are laden with harmful and potentially harmful ingredients (I found this video at Huffpo). I should also mention that I have become extra-motivated to try this experiment based on this recent post by Brynn Jacobs. First, the fast-paced video featuring "Umbra": Now a short detour to the Environmental Working Group website, where you can determine all of the nasty chemicals in your shampoos, conditioners and other products. The EWG "Cosmetics" database is here. I went to straight to my bathroom and dug out various bottles each of shampoo and conditioner. My Pantene "Full and Thick" shampoo contains all of the following (among other chemicals): METHYLCHLOROISOTHIAZOLINONE, ETHYLENE OXIDE, 1,4-DIOXANE, ETHYLENE OXIDE, 1,4-DIOXANE) NITROSAMINES) COCAMIDE MEA, METHYLISOTHIAZOLINONE, SODIUM LAURETH SULFATE. Various of these chemicals are associated with the following things: Neurotoxicity, Allergies/immunotoxicity, Organ system toxicity (non-reproductive) Organ system toxicity (non-reproductive), Irritation (skin, eyes, or lungs). I checked out a bottle of Suave Professionals Sleek Shampoo and it contained a comparably ominous list. The Revlon Aqua Marine Moisturizing Shampoo was even worse in that it contained four chemicals associated with cancer. Then I looked up two bottles of hair conditioner. The Garnier Fructis Fortifying Conditioner - Sleek & Shine has a comparably nasty list of chemicals --Umbra urges that these chemicals are totally unnecessary for washing one's hair. I couldn't find the Citre Shine Daily Revitalize Conditioner with Shine-Infusing Citrus Extracts on the EWG website, but I carefully read the fine print on the back label and plugged four of those chemicals into the EWG site; they all came up as bad, despite the front label's suggestion that this product contains "healthy" ingredients. I suppose the theory is to balance out each industrial chemical with a whiff of something healthy-sounding like "citrus extract." BTW, isn't it ironic to read all of those the benign-sounding names of these products and then compare those names to the long lists of chemicals within? What is Umbra's solution to this apparently unhealthy situation? She is encouraging us to make our own shampoo and conditioner (this is the same advice offered by Colin Beavan). For shampoo, she recommends that we mix a tablespoon of baking soda with each cup of water. Shake it each time before using it. For conditioner, mix 1 tablespoon of apple cider vinegar with each cup of water. She says that the vinegar smell goes away after you rinse. As soon as I publish this post, I'm going to the kitchen to mix up a batch of each. I'm appearing in court tomorrow, and my hair and scalp, for the first time ever, will not be drenched in potentially harmful chemicals. I promise to report on the experience after I use these home-made hair products for a few days.
