12 Best Zero Waste Shampoo And Conditioner Bars For Your Hair (2023)

Did you know that most shampoo bottles contain 70 to 80% water? If you just fell out of your chair, then we can both continue reading on the floor. Yep, water is the main ingredient to help dilute the detergent and make it easier to spread. If you look at the back of your bottle, it’ll say aqua which is just tap water added to the ingredients.


You can think of a shampoo bar as a concentrated version of commercial shampoo in a bottle. Just like the Tru Earth detergent strips or the Earth Breeze ones are concentrated versions of washing detergent, without the plastic waste.

Read the Earth Breeze Detergent Sheets Review

Additionally, it will outlast your bottled shampoo by two to three times.  A 1.9oz shampoo bar can last up to 80 – 100 washes, which equals three 250ml bottles.

But it also depends on your usage. Mine usually lasts for about two to three months, and I wash my hair daily.

If that is not reason enough to ditch the plastic bottle and swap over to zero waste shampoos, then maybe the fact that yearly 1164 football fields of bottles are going to landfills.

They cause many other problems, from taking thousands of years to degrade and releasing harmful chemicals into the groundwater, or bottles ending up in our oceans and nature, where they can do further harm.

Plastic breaking into microplastic, which is ingested by marine life and ourselves. You see, there are plenty of benefits to moving away from conventional shampoo in plastic bottles.

But what about the transition period Mr. Zerowasteman?

Good question. I am glad you asked. And drumroll, please…

Yes, there is going to be a transition period. If you have been washing your hair with chemical-laden shampoos for the last 20-30 years (I am not very good at math), it will naturally take some time for your hair to adjust to natural shampoo bars without any harsh chemicals.

You might notice your hair feeling a bit yucky after the first wash, even greasy or oily hair. That is because you have been slapping chemicals on your poor scalp and it takes some time for the natural oils to come back to their healthy performance. Don’t sweat it just yet, it might take you 3-4 washes until your hair has adapted, and trust me, you will never want to go back after that.

If you feel like there is no transition period, then that might be due to the shampoo bar still containing too many chemicals. But this article will give you a good idea of which zero waste shampoo brands are right for you.

You might want to try an apple cider vinegar rinse.

Sometimes the shampoo bar can leave a bit of residue in your hair making it feel waxy or oily. You can use conditioner bars or make your own apple cider vinegar rinse.

  • 1/2 T to 4T of apple cider vinegar (ACV)
  • 8 ounces of water
  • Dry hair likes less ACV, and oily hair likes more
  • Additionally, add some herbs or essential oils to make it smell nice.

Benefits of ACV

  • Balancing, it has a natural PH.
  • Antimicrobial, really good for itchy scalps or dandruff.
  • Clarifying;  it also helps exfoliate dead skin cells and wash away buildup from hard water and hair products like dry shampoo.

What is the best zero waste shampoo?

The options have exploded, and there are so many different “greenwashing” companies, which is why it’s a bit difficult sometimes for the average user to pick the right ones.

When I say greenwashing, I mean that sometimes these companies market it as a green product. By writing terms like eco-friendly or biodegradable, which sadly in most cases is just a marketing strategy. But how can you see through the BS?

You can learn more about greenwashing in this little video I made

What is Greenwashing | The Zerowasteman explains

However, often traditional shampoos still use unsustainable palm oil, SLS and sulfates, sodium Laureth, sulfate SLS parabens, artificial fragrances, and silicon. 

And yes, you guessed it right, if they get washed down the drain, they’re also bad for the environment.

So that means you are getting safer, healthier, and more natural ingredients when you use a zero-waste shampoo.

But what does Zero Waste Shampoo mean?

Zero waste shampoo bars are concentrated versions of shampoo bottles without the need for single use plastic packaging.

High-quality shampoo bars do not contain palm oil, Sodium Laureth Sulfate (SLS), parabens, artificial fragrances, and silicone. Zero waste shampoo is plastic-free and easy to use.

Pros and Cons of Shampoo Bars

Benefits of using shampoo bars:

  • They are small and compact
  • They are easy to travel with
  • They last longer
  • They have non-toxic options
  • They don’t use plastic packaging
  • You can get bars that do both hair and body

Cons of using shampoo bars:

  • If stored wet, they may melt away quickly
  • Still contain some chemicals
  • Take a transitioning period

Avoid these ingredients:

The problem with SLS is that it is designed to leave your hair feeling silky smooth and clean; however, it is a surfactant soap that can dry out your hair and cause psoriasis or dandruff for some people. This means you would have to use a conditioner as well. Personally, I have sensitive skin, and I prefer not to put too many chemicals on my skin. 

Which one is the best Zero Waste Shampoo?

This obviously is different for everyone, since some of us have oily hair or frizzy hair but these are the products that we personally like and feel confident to share with you.

Some shampoos use silicone for the feel, not ethique. We didn’t find any harmful ingredients in their shampoos hence why they are on top of this list.

6. Lush

Lush is a well known and big cosmetic brand. But if you want a product with no added chemicals, this is one to avoid. I was a bit sad when I learned that they use SLS to create foam and artificial fragrances. So if you want to use natural shampoo bars then skip this one.

Chagrin Valley Soap explains that we were all using natural shampoo bars before the Industrial Revolution. Only since the introduction of liquid “detergents” is our hair been stripped from natural oils and we need to use conditioner to add the oils back to our hair.

Thankfully you are here to move away from traditional shampoo and perhaps test one of the charging valley hair care products.

Some shampoos contain sustainably farmed palm oil, which can leave a residue in your hair. They also make an apple cider vinegar rinse to get rid of any residue.

First, they add lots of herbs and botanicals to the oils, and only then the creation of their vegan shampoo bar begins. Great for frizzy hair.

The aluminum bottles are 100% recyclable and not only that, but they also offer a refill program. Once you have used up your shampoo and conditioner, you send the empty bottles back and keep the pump for your next plaine shampoo.

You can subscribe to get your shampoo before it runs out, or order when you are running low.

Clean the old bottle and put it back in the return box. Once your box is full hand it to the mailman and voila the shipping cost is covered by plaine.

In the end, this is just a tiny selection of soaps that are out there. But I know how it feels when you are standing in the supermarket in front of the shelf trying to pick the right product out of 200 options.

My hope is that depending on where you live you find something in your country or at least nearby. Remember the carbon footprint from travel.

Even better if you go to your local zero waste store and get it there. The one near my place actually makes its own soap, and they have a soap-making class, which is pretty cool if you want to do it yourself.

Rule of thumb: If you come across some soap that isn’t listed here, but you need to get soap, check and make sure that the soap does not contain any of the following:

  • SLS
  • phthalates
  • silicone
  • palm oil
  • artificial fragrances

Usually the fewer ingredients, the better. And obviously the packaging. If it is wrapped in plastic, make a statement by not buying it and be proud of yourself. Happy shampooing.


I have not used every shampoo myself, and I am not responsible for your skin. I researched the heck out of it and often use amazon reviews to help you make a clear decision. However, I would in most cases suggest buying through the company itself, since amazon often uses plastic packaging even for their zero-waste shampoo bar section.

Also if you like to change the settings on amazon to receive more eco-friendly packaging, check out this video I made.
