Finding the perfect natural shampoo bar for your unique hair type can be tricky. But when you factor in concerns like plastic waste and toxic ingredients, the search becomes even more challenging.
Like many other products in your home, regular shampoo is loaded with harmful chemicals like parabens, phthalates, and other synthetic additives — 4 in 10 shampoos contain chemicals linked to health issues like hormone disruption, allergies, and skin issues.
It’s frustrating to think you might be washing your hair with ingredients that could harm your health or pollute the planet. Every plastic shampoo bottle tossed out adds to the 50+ kg of packaging waste you generate each year, compounding the environmental crisis.
Natural shampoo bars can offer a simple, effective solution. There are plenty of them free from harmful substances, and they also don’t contribute to plastic waste. Their solid form is lighter to transport, cutting down CO₂ emissions, and often comes in biodegradable packaging.
I’ve tested the best non-toxic shampoo bars, and I’m excited to help you find eco-friendly options that support your health while protecting the planet.
Why Choose a Natural Shampoo Bar?
Even though many shampoo bars help you cut down on plastic, they still can still be loaded with toxic substances that aren't exactly good for your health.
Some of these chemicals include sulfates, parabens, silicones, phthalates, synthetic fragrances, formaldehyde-releasers, polyethylene glycols (PEGS), PFAS, BHT, BHA, and lilial. Many of these unwanted —and unnecessary—ingredients are mild irritants, allergens, endocrine disruptors, and even potential carcinogens.
Some are irritants and potential hormone disruptors, and phthalates—known as the “everywhere” chemical—have even been linked to higher risk of breast cancer and infertility. The tricky part? Phthalates can hide behind the term “fragrance” on labels, leaving you in the dark.
Fortunately, there are many non toxic alternatives that are better for your health. We know it can be overwhelming to test different shampoo bars to find the best option for your hair. So, we've selected the top 11 natural shampoo bars to seamlessly integrate into your non-toxic lifestyle!

How We Choose the Best Natural Shampoo Bars
When picking out toxin free shampoo bars, we start by zeroing in on what’s inside. Ingredients are everything. I’ve learned to look beyond the promises on the label and dive deep into each formula. We also factor in a brand’s commitment to clean beauty, real-world performance (based on both personal trials and customer reviews), and how well it supports scalp health.
For me, the best natural shampoo bar isn’t just about being non-toxic, but also tailored to meet the specific needs of your hair.
"Best" vs. "Better"
To simplify your search, I’ve divided my top picks into two categories:
• “Best” Natural Shampoo Bars: These standouts use natural or organic ingredients and skip common irritants like harsh surfactants, synthetic fragrances, PEGs, and preservatives, making them standout choices in non-toxic hair care. They’re gentle, sustainably produced, and a true pleasure to use—perfect if you have a sensitive scalp or want the purest option.
"Better" Non-Toxic Shampoo Bars : These non toxic bar shampoos still feature clean, plant-based formulas. However, they lean on naturally derived surfactants to enhance cleansing power. While effective, these surfactants may be slightly more intense for sensitive skin. They’re great if you’re looking for a solid step up from conventional options, but not as “pure” as the “Best” category.
Ultimately, it comes down to what’s most important to you—be it total purity, gentle performance, or a balance between the two. I’m here to share my experiences and insights so you can confidently choose the perfect fit for your hair and values!
