Non-Toxic Shampoo: Ingredients to Avoid & What to Look For
Finding a non-toxic shampoo that cleans effectively without exposing you to harmful chemicals can be tricky. Many shampoos, even some labeled as “natural,” contain problematic preservatives, synthetic fragrances, and harsh surfactants. Below, we break down the key ingredients to avoid and what to look for in a truly safe, non-toxic shampoo.
Surfactants
Surfactants are the key ingredients that make shampoos (and all soaps and detergents) effective. They help water break down oil and dirt, allowing them to be rinsed away. However, not all surfactants are created equal—some are safe, while others come with health and environmental concerns.
Many conventional shampoos rely on harsh surfactants like sodium laureth sulfate (SLES) and, which can be irritating to the scalp and may contain harmful contaminants. Cocamide DEA is an actual carcinogen and should always be avoided. Unfortunately, some natural shampoos also use these questionable surfactants.
Safer Surfactants in Non-Toxic Shampoo
If you’re looking for a non-toxic shampoo, keep an eye out for gentler, biodegradable surfactants like:
- Decyl glucoside
- Lauryl glucoside
- Potassium cocoate
- Coco glucoside
- Sodium cocoyl isethionate
- Sodium lauroyl methyl isethionate
- Caprylyl/capryl glucoside
- Sodium lauroyl glutamate
The problem with these is that they tend not to lather as well as some of their more traditional (but less safe!) counterparts, so it can be hard to find high-performing, non-toxic shampoos that rely only on these surfactants.
Non-Toxic Shampoo Gray Area
One of the most confusing surfactants is cocamidopropyl betaine. While it can be safe and mild, it can sometimes be contaminated with harmful byproducts like nitrosamines (carcinogens) and 3-dimethylaminopropylamine (also known as DMAPA, and irritants). While derived from coconut oil, cocamidopropyl betaine is heavily processed and not as “natural” as some marketing suggests. Potential marine toxicity raise mild environmental concerns. Choosing a DMAPA-free, third-party-tested shampoo brand can help minimize these risks.
Similarly, while disodium laureth sulfosuccinate itself is considered a mild surfactant, it can be at risk of contamination due to ethoxylation. The best way to assess this is to look for certifications (EWG verified, ECOCERT, EU standards), transparency about purification methods, or labels that explicitly say “1,4-dioxane-free.”
Finally, cocamidopropyl hydroxysultaine has a low potential for skin, eye, or lung irritation. However, there are once again concerns about possible contamination with DMAPA and nitrosamines during its manufacturing process.
At Gimme the Good Stuff, we evaluate shampoos with cocamidopropyl betaine, disodium laureth sulfosuccinate, and cocamidopropyl hydroxysultaine on a case-by-case basis:
✅ If a brand discloses third-party testing or is verified by EWG, it may make our Best Stuff list.
⚠ If there’s no transparency about contamination risks, the product lands in Good Stuff or Okay Stuff, depending on its other ingredients.
Coco Betaine in Non-Toxic Shampoo
Some brands use coco betaine instead of cocamidopropyl betaine. Coco betaine is a milder, less processed alternative that is less likely to cause irritation or contain impurities. It can, however, potentially irritate very sensitive skin, so if you have allergies, eczema, or rosacea, it’s best to patch-test first.

Hey Teresa. I’ve been using these babies on our family for the last 12 months, mainly cos they’re sulfate and paraben free and vegan but also cos there just great for our life style….so maybe check them out ;-) Ricki (that’s a female Ricki, in case you were wondering, proud mom of three!)
Teresa
What type of shampoo bar do you use? I am not familiar with them. Thanks!
Maia James
Not terrible, but there are better brands (contains phenoxyethanol among other ingredients).
Charity Dicus
I use the Carina Organics shampoo. I like it so far. They have an unscented line with about 15 products.
Stephen
How do you feel about the Burts Bees shampoos?
Maia James
Sneaky Stuff. Among other concerns, it has methylisothiazolinone as a preservative.
Ana Uy
Hi I wanted know if this is a good stuff product because on another site the Kirkland Moisture Shampoo was listed as a paraben free, sulfate free, gluten free and 100% Vegan shampoo. Is this considered a sneaky product? Cuz on the back I saw ingredients that I’m not sure of. Have you tried this product from Costco?
Joann
Could you rate Whole Foods 365 line of shampoo?
Maia James
I don’t know that one, but will add to the list for when we update the Nontoxic Shampoo Guide!
julia splan
Acure makes me itch so I would suggest trying something else.
Katie
Is the Hask Monoi Coconut oil line safe?
Maia James
Don’t know that one, but will add it to the list:)
Kristin
Any thoughts on Alaffia Everyday shampoos?
Maia James
Hi there-
Hard for me to say since I have dry hair! People love Acure’s clarifying shampoo: https://gimmethegoodstuff.com/store/acure-organics-lemongrass-argan-stem-cell-shampoo-for-all-hair-types/
Or you could try John Masters.
Jessica
What is the best shampoo brand and formula, (or im even open to bar soap)for oily hair?
Maia James
Eh, it’s not terrible, but not quite Good Stuff.
Lisa
Hello,
What are your thoughts on Sukin hair care line?
Maia James
We haven’t! Will add to the list:)
Rachel Eatin
Have you looked into monat. I am happy with John masters but have some friends trying to sway me towards Monat. Thank you!
Maia James
Don’t know that one, Gemma…will look into it!
Gemma
What about “New Wash?”
Maia James
I am not concerned about soy in hair care products, personally. Their shampoo does, however, not contain sodium benzoate, which I know some people would rather avoid.
Maia James
I agree with you, Louisa. Terressentials shampoos are the Good Stuff!
Kathryn
What about John Masters use of soy in their products? I want to absolutely love them(they do wonderful things for my hair) but that point kind of catches me.
Maia James
I consider most of Aveda products Sneaky, although the company has made strides in recent years and become a bit safer.
Maia James
Depends on the product, but some BWC stuff is unfortunately Sneaky.
Maia James
Hi Clara-See above, where I reviewed the Shea Moisture shampoo:)
Maia James

Hi Meghann! Unfortunately, Diva Curl is Bad/Sneaky, in my opinion. Say high to Mariah:).
Meghann (friend of Mariah BB!!)
What about the diva curl line of products? Good, Bad, Sneaky?
Thank you!!!!
Lauren
Hi!
Do you have an opinion on the wen hair loss scandal? I am interested in trying a new product called “new wash” by “hairstory” but am nervous. Your opinion would be greatly appreciated!
Patricia L McCoy-Panniell
What about the Miss Jessie’s line of hair care products?
Diana Taro
What about Beautycounter products? Its a company with a mission of making sure its products are safe.
Shannon Brown
Are Aveda products considered safe?
Noelle
What about Beaty Without Cruelty (BWC)?
Ally
what do you mean by a “warning”? Are you referring to the ingredients?
JoAnne
Hi I just wanted to let you kniw that when I attempted to purchase the Acure shampoo and Conditioner on another site, I received the same warning that I do for other shampoos.
Louisa
Terressentials makes fantastic shampoos for all hair types.
Heather Kral
I use SHIKAI
I buy from Vitacost
Opinions?
Clara
What are your thoughts on Shea Moisture products? Are they considered safe?
Thanks and God bless.
Emily
The no poo method can actually damage your hair after a while. Be careful with it. I am using shampoo bars instead and they are great!
Lian
What is the no poo method and how can
I obtain it?
