Shampoo product reviews from the community

Who is doing the investigating of ingredients. Cocamidopropyl Betaine is a very bad ingredient I thought.

Ann Sawall, 7 months

I prefer this sulfate-free shampoo for my teen girls to use. They are picky and use this without complaints. I like it for sulfate-free and short (ish) ingredient list.

Buying guide for Shampoo products

The issues

The average U.S. consumer uses about 10 cosmetic products every day, including soap, shampoo, lotions, deodorants and fragrances. These products can contain hundreds of ingredients, and their regular use can result in chronic exposures to low levels of potential hazards. The most important issues associated with shampoos include:

  • Health concernsShampoo ingredients can pose potential human health hazards. In most cases, a chemical that provides a shampoo with a desired hair care property may also exhibit hazard profiles that risk-averse consumers would prefer to avoid. In the worst cases, poor product stewardship results in some manufacturers formulating shampoos to include recognized carcinogens like phenolphthalein or butylated hydroxyanisole.
  • Ingredient disclosureComplete lists of shampoo ingredient lists are often unavailable, creating a significant barrier to assessing the safety of personal care products. Although companies are required to disclose the ingredients in personal care products, these lists rarely contain information about percent composition (needed to assess potential exposures) and often rely on generic terms like “fragrance,” which make it impossible to assess whether there are any problematic ingredients present.
  • Contamination concerns — The Food and Drug Administration only requires cosmetic firms to list “intended” ingredients in products, which allows manufacturers to hide the presence of other ingredients from consumers. For example, shampoos that use sodium laureth sulfate as a foaming agent, are often contaminated with the recognized carcinogen 1,4-dioxane, a byproduct of a chemical processing technique called ethoxylation. Only after consumer organizations tested products have manufacturers committed to reformulate their shampoos to reduce levels of this shampoo ingredient. Similar concerns exist in products that contain formaldehyde-generating ingredients like DMDM, hydantoin or nitrosamine-generating ingredients like diethanolamine (DEA) and triethanolamine (TEA).
  • Inadequate regulationPersonal care products are not subject to safety reviews by the FDA before they are put on the market, and the agency is frequently criticized for its lax approach to regulation. The European Union, for example, has banned the use of more than 1,000 substances in cosmetics; in contrast, the FDA has only prohibited the use of eight substances in cosmetics. There is widespread skepticism that the current regulatory system is sufficiently protective of human health.

What to look for

Look for shampoos that are certified as sustainable by Cradle-to-Cradle or as compliant with the standards set by EcoLogo or the Natural Products Association for personal care products. Also keep an eye out for other certifications like the NSF “Made with Organic” and Quality Assurance International seals, which focus on ensuring that “organic” marketing claims are valid for an entire product rather than just a few constituents.

Rating Shampoo products

Overview

To rate a personal care or household chemical product, GoodGuide considers the following attributes:

  • A health hazard rating based on the number of product ingredients categorized as low, medium or high health concern;
  • Indicators that the product exhibits other negative aspects (e.g., does the product contain ingredients that have been banned or subjected to regulatory restrictions);
  • Indicators that the product is among the best on the market in its category (e.g., has the product been certified as safe or healthy by a credible third-party);
  • Indicators of data gaps that preclude evaluation of the product (e.g., no or inadequate disclosure of product ingredients).

Categorizing Ingredients by Levels of Health Concern

Defining Levels of Health

In order to identify ingredients of health concern, we utilize the science of health hazard assessment and rely on lists of chemicals labeled hazardous by various authoritative organizations. GoodGuide tracks whether chemicals are recognized or suspected of causing any of twelve major types of human health problems, ranging from cancer to endocrine toxicity to skin or eye toxicity. We combine this hazard data with chemical potency, human detection frequency and toxicity testing information, in order to assign ingredients to four levels of health concern: none, low, medium and high.
