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.

Any thoughts on The Honest Company’s shampoos and conditioners? Thanks!
Maia James
I’m not a big fan of Alba—it has a lot of synthetics, including fragrance.
Maia James
I consider this Good Stuff:)
Metka
I also found Trade Joe’s Tea Tree Tingle shampoo…any thoughts on this product?
Metka
Hi! Is there any professional hair shampoo(used and sold in hair salon) that is safe to use? Those make my hair feel so amazing, I tried most of the shampoos you listed as the good stuff and none of them can compare to the way my hair feel.
Lee
Hi,
Any thoughts on Alba Botanica? I have been using this but just realized they have a bad rating on EWG.
Thanks!
alexandra kammer
Hi Maia,
What is your experience with Rahua products? Thank you!
Maia James
No, I don’t know this brand! I will add to our list to investigate. Thanks!
Maia James
Yes, it’s possible that they’ve changed their formula since we updated this guide. What’s listed on the bottle should be accurate!
Maia James
Arbonne doesn’t share all of their ingredients, so it’s hard to judge their products, but what has been disclosed does concern me, so I hesitate to call this Good Stuff..
Jennifer Bowlin
What do you think/have you tried Loma haircare products?
Hailey
Great read!
My only problem with this is that I use Aubrey and I don’t see retinol (or vit A) anywhere on the ingredient list. I even stopped to get more the other day and couldn’t find that ingredient in any of their shampoo and conditioner products. Sometimes EWG is outdated. Any thoughts?
Louise
Great read! What’s your thoughts on Arbonne products?
Thanks!

This is the second positive review I’ve seen on one page for this product and no replies to it. I also noticed that your contact info (just as the other reviewer) has the product name in it. Are you a representative of this product? Are you being paid for these reviews? Is so, think this is such a sneaky way to drum up sales!! Very dishonest in my opinion!
Peggy Chase
Are you a representative of this line? Do you get paid to give this review?!
Maia James
Not a huge Ava fan (see here: https://gimmethegoodstuff.com/is-ava-anderson-sneaky-stuff/)—I need to dig into Pure Haven to see if they’ve addressed all these issues in their rebrand!
Heather
What are your thoughts on AvaAnderson/Pure Haven Essentials?
Toni
I love Monat haircare products they are salon quality but nontoxic they have a great list of no’s. After being diagnosed with breast cancer I tried everything! But my hair was feeling gross I finally found Monat which also had 3rd party clinical studies proving regrowth and follicle strength which I really needed, my hair honestly had never felt so healthy and thick too! You can check it out here http://134430@mymonat.com or context me for more info
Maia James
Don’t know this one, but will add to our list!
Maia James
I haven’t yet, but will add to the list!

I am looking into a new product and I wanted some feed back
Acti-labs Capill Hair Shampoo
Acti-labs Capill Hair Mask
Acti-labs Capill Hair Lotion any feed back would be great
Frankie
Hello, I greatly appreciated your list as I was wondering through Natural Pantry trying to pick out a safe shampoo today. Have you reviewed the NutriBiotic brand? If not would you be able to?
Thank you!
Maia James
I just took a look, and while it’s not natural by any stretch, the ingredients don’t look bad. It does contain a few I’m not crazy about, like phenoxyethanol.
LisaCM
I was looking into Modere products. But, I can’t pronounce many of the ingredients in the shampoo or toothpaste. My friend said they are organic and listed safe on EWG. Hm. What say you please?
Raissa
Fantastic!! I love it, thanks so much.
Maia James
I can’t find anywhere that lists all the ingredients in this product.
Alex
What about renpure?
Maia James
Unfortunately, I’d have to call this Sneaky Stuff, as it contains synthetic “parfum” and a host of other synthetics.
Alice
Hi,
how about the Pureology line? It claims all its ingredients are vegan. I usually use the purifying shampoo.
Maia James
Thank you! I like the Babo Swim/Sport line: https://gimmethegoodstuff.com/store/babo-botanicals-swim-and-sport-shampoo-wash/ (for adults as well as kids).
Raissa
What is the best shampoo for someone that swims regularly in a salt water and chlorinated pool? Love your site by the way :)
Maia James
Meh. Okay Stuff (meaning not Good Stuff but not quite Sneaky), in my opinion.
Heather
Are Babo Botanicals no longer “good”? It looks like it was removed from they list
Ellen
What is your opinion on the Bert’s Bee line of shampoo?
Ina Kleimann
I love my monat hair products. Suffered too long from hair loss, finally seeing new grow and way less shedding.

I personally don’t worry about the tiny amounts of these essential oils in otherwise Good Stuff products, but of course it’s a personal call. You can always go with unscented products if you want to avoid it all together. As for “natural fragrance,” that just means it’s essential-oil based rather than synthetic.
Maia James
I don’t know that brand, actually. I usually recommend this to my clients in search of dandruff shampoo: http://amzn.to/2azMhcQ

Hi Maia. I just started using the Acure clarifying shampoo which I love, but I noticed it contains Rosemary essential oil which I’ve read is not safe for young children. Do you feel that oils in commercial beauty products or cleaning products are concerning?
Also I saw that Acure makes a 4-1 foamer for babies in a citrus scent but it lists “natural fragrance” on the label. What does this mean?
Thank you!!!
MS
Any thoughts on PURA D’OR Scalp and Dandruff Therapy Shampoo with Argan Oil? If not good, any advice on an anti-dandruff shampoo?
Maia James
I would call this Okay Stuff. Definitely not all-natural and a lot of unstudied ingredients. But nothing that’s definitely bad:)
Maia James
Total sneaky stuff! They have parabens!
paola

Amber
How do you feel about Lush products?
Maia James
Their website is down so I can’t check ingredients.
Nora Anderson
Hey there! Thanks for the shampoo recommendation! I agree about the sulfate part not being necessarily bad, but I try to avoid them because they make my hair really dry. It’s what makes the shampoo sud, but it strips away my hair’s natural oil. Have you heard about soapberry products? Tree to Tub, the website, sell them. I heard about it and I’m interested because it says that it cleans and moisturizes at the same time, so it’s like a shampoo and conditioner at the same time. If you have any info on that let me know.
Maia James
Yes, I consider John Masters Good Stuff:)
Julie
Are all John Masters products free from any bad chemicals?
Maia James
John Masters is probably best for that:)
Natalie Cannatella
Hi, I was wondering which of these shampoos is best for preserving color treated hair? Thank you in advanced! :)
Maia James
