The short version
The best organic shampoo is Avalon Organics. It is made with certified-organic botanicals, is sulfate-free, paraben-free, and vegan, and is easy to find in targeted formulas, which is why it earned our top Organic Integrity Score of 91 out of 100. For a fully USDA-certified formula, OilnGlow USDA Organic is the pick. On a budget, Acure gives you a clean, vegan, sulfate-free wash at a friendly price.
An honest note on certification: truly USDA Organic-certified shampoos are uncommon, because the cleansing agents (surfactants) in shampoo are difficult to certify organic. Most quality “organic shampoos” are sulfate-free and made with a high share of organic ingredients rather than carrying a full USDA seal. We say clearly which is which, and always recommend reading the label.

Best overall: Avalon Organics
Avalon Organics is our top pick because it balances clean formulation, wide availability, and a strong reputation. It is made with certified-organic botanicals, is sulfate-free, paraben-free, and vegan, and comes in targeted lines (for example thickening, moisture, and scalp) so you can match it to your hair. It is a “made with organic ingredients” product rather than a fully USDA-certified one, which we weigh in the score.
What we liked: certified-organic botanicals, sulfate- and paraben-free, vegan, targeted formulas, easy to buy.
Keep in mind: it is not a fully USDA Organic-certified product, so read the ingredient list for the organic content you want.
What buyers say: Buyers like the scents, the gentle cleanse, and the reliable results across the different formulas. Some ingredient-focused shoppers wish for a higher certified-organic percentage.
Best USDA-certified: OilnGlow USDA Organic
If a full USDA Organic seal is your priority, OilnGlow is the pick. It is USDA organic certified, fragrance-free, and free from sulfates, parabens, phthalates, and petroleum, and it leans on botanicals like rosemary and saw palmetto often chosen by people concerned about thinning hair.
What we liked: USDA organic certification, fragrance-free, free of sulfates and other common irritants.
Keep in mind: USDA-certified shampoos foam more gently than conventional sulfate shampoos, which is expected.
What buyers say: People seeking a genuinely certified formula and those with sensitive scalps report the best experience. Some miss the big lather of a conventional shampoo.
Best budget: Acure
Acure is the value pick. It uses organic ingredients in sulfate-free, vegan formulas at a low price, making it an easy way to move the whole household to a cleaner shampoo without a big cost jump.
What we liked: organic ingredients, sulfate-free and vegan, low cost, several formulas.
Keep in mind: made with organic ingredients rather than fully USDA-certified; check the label.
What buyers say: The price and clean formula are the main draws, and many report good everyday results. A few find the lather modest.
Simple and gentle: Sky Organics
Sky Organics keeps things simple with gentle, sulfate-free formulas made with organic ingredients, from a brand with a strong clean-beauty reputation (and our top castor oil pick). A good choice for sensitive scalps.
What we liked: gentle sulfate-free formula, organic ingredients, trusted brand.
Keep in mind: confirm the specific certification and formula for your hair type on the label.
What buyers say: Sensitive-scalp users like how gentle it is, and brand fans trust the sourcing. Some want a wider range of targeted formulas.
Best multi-use castile: Dr. Bronner’s
Dr. Bronner’s Pure-Castile soap is not a dedicated shampoo, but many people use it as one for its Regenerative Organic Certified oils and exceptional transparency. It is best for simple hair routines and those who like one clean product for many uses.
What we liked: Regenerative Organic Certified oils, sulfate-free, multi-use, unmatched ingredient transparency.
Keep in mind: as a castile soap it should be diluted, and some people need an acidic rinse (like diluted apple cider vinegar) afterward; it is not formulated specifically for hair.
What buyers say: Minimalists and travelers love the versatility. The common learning curve is dilution and, for some, adding a follow-up rinse for softness.
How to choose an organic shampoo
- Certification, realistically. Full USDA Organic shampoos are rare because surfactants are hard to certify. Prefer a USDA or Regenerative Organic option where it exists; otherwise choose a sulfate-free formula with a high share of clearly listed organic ingredients.
- Sulfate-free. Avoid SLS and SLES, which strip natural oils and can dry out hair and irritate the scalp.
- Skip the usual offenders. Look past parabens, phthalates, synthetic fragrance, and dyes.
- Match your hair. Choose a formula for your need, moisture, volume, scalp, or color-safe.
- Expect gentler lather. Sulfate-free shampoos foam less; that is normal and not a sign it is not working.
How to use organic shampoo
Switching to a sulfate-free organic shampoo can take a couple of weeks as your scalp rebalances after conventional shampoos. Use a small amount, focus on the scalp rather than the lengths, and rinse well. If hair feels waxy at first (common when using castile soap), an occasional diluted apple cider vinegar rinse can help. Follow with a matching conditioner, and do not over-wash, two to three times a week suits many hair types.
How we researched this guide
We are a research-based review site. We did not lab-test these shampoos ourselves. We compared each against its certification records, ingredient list, sourcing, and the weight of aggregated buyer and expert feedback, then scored each with our 10-criteria Organic Integrity Score, being careful to distinguish fully USDA-certified products from those made with organic ingredients. No brand paid to be included or ranked. Read the full method on our How We Research and Rate page.
Frequently asked questions
What is the best organic shampoo?
Our overall pick is Avalon Organics, because it is made with certified-organic botanicals, is sulfate-free, paraben-free, and vegan, and comes in targeted formulas. For a fully USDA-certified formula, OilnGlow USDA Organic is the pick.
Are there any fully USDA Organic shampoos?
A few exist, such as OilnGlow, but they are uncommon because the surfactants that make shampoo lather are difficult to certify organic. Most quality organic shampoos are sulfate-free and made with a high share of organic ingredients.
Why is sulfate-free important in shampoo?
Sulfates like SLS and SLES create heavy foam but strip natural oils, which can dry out hair and irritate the scalp. Sulfate-free organic shampoos clean more gently.
Does organic shampoo lather less?
Yes, and that is normal. Without sulfates, the lather is gentler. It still cleans effectively; focus the shampoo on your scalp and rinse well.
Can I use Dr. Bronner’s castile soap as shampoo?
Many people do. Dilute it, focus on the scalp, and consider a diluted apple cider vinegar rinse afterward for softness, since castile soap is not formulated specifically for hair.
