15 Best Zero Waste Shampoo and Conditioners Without the B.S.

As an Amazon Associate, Ecotero earns from qualifying purchases.

Despite their eco-friendly packaging, many “zero waste” shampoo and conditioners today actually contain unsustainable and harmful ingredients that can cause harm to the environment and your health.

And while plastic-free packaging is a prerequisite, there are other things to consider when shopping for a zero waste hair shampoo and conditioners…

Especially if you’re looking for the best.

So without further ado, let’s shampoo…

How to pick the best zero waste shampoo and conditioners?

Many brands today are merely “greenwashing” or making misleading claims to appeal to the eco-conscious market. 

So when shopping for genuine zero waste shampoo and conditioners, look for:

  • Palm Oil Free – Palm trees only grow in tropical regions, so rainforest is being cleared to make way for palm tree plantations. The clearing process produces tons of CO2 emissions, destroys natural habitats, and causes massive biodiversity loss.
  • SLS-free – SLS (Sodium lauryl sulfate) is a surfactant(foaming agent) that can cause minor irritations to sensitive skin such as itchy scalp, hair damage, and even hair loss.
  • Cruelty-free – The product and the ingredients used in creating the product were not tested on animals. Look for accreditation such as Cruelty-Free International, Leaping Bunny, or PETA Certified.
  • Vegan – Vegan products contain no animal ingredients or animal by-products.
  • Organic Ingredients – Organic ingredients are grown without pesticides, synthetic fertilizers, and harmful chemicals.

We reviewed dozens of zero waste shampoos and conditioners with the above in mind, and came up with 15 products we considered to be the best.

We regard these three as the overall top zero waste shampoo and conditioners based on ingredients, eco-friendliness and ethical production.

Plaine Products eco-friendly shampoo comes in a reusable and refillable metal container.

It is SLS-free, cruelty-free, vegan, palm oil-free, and made with a biodegradable formula – with no artificial scents.

Many people love this eco-friendly shampoo because it doesn’t leave your hair dry and brittle (like being stripped from natural oils), so you won’t need a conditioner. 

It also lathers and bubbles up quickly without using too much water and is easy to rinse as well.

However, this shampoo is at the lower half of this list because, in our opinion, sending empty bottles to the company for a refill and then shipping it to you again will leave more carbon footprint.

Furthermore, this shampoo is liquid, so you probably can’t carry this with you if you’re traveling via plane, or you’ll risk getting in trouble with the TSA.

Hence, you would need to buy another shampoo when traveling, which is not really “zero wastely.”

Nonetheless, we highly recommend Plaine Products if you’re looking for a zero waste shampoo and conditioners for daily use at home.

The price starts at  $30 for a 16oz (473ml) metal bottle.

Scents: Rosemary Mint Vanilla and Citrus Lavender

Pros

  • Suits both straight and curly hairs

  • It has a mild, gentle smell

Cons

  • Expensive
  • Not a travel-friendly shampoo
  • Sending empty bottles to the company for a refill will cause more carbon footprint

FAQs

Why is shampoo bad for the environment?

Ever asked yourself “is shampoo eco-friendly?”

Well, most conventional liquid shampoos aren’t.

The obvious reason is that they are in liquid form, so most of them have to be contained in plastic bottles.

Secondly, unlike small shampoo bars, liquid shampoos are bulky and heavy so they create more carbon footprint during shipping.

Bulky containers take up so much space in transport while heavy cargo require more fuel to ship.

Third, many shampoos contain harmful chemicals and unsustainable ingredients.

For instance, most shampoos contain SLS (Sodium Laureth Sulfate), a foaming agent that can be harmful to aquatic animals when released into the environment.

Another common ingredient in shampoos is palm oil. 

Palm trees only grow in tropical regions, so to produce palm oil, rainforests are being cleared to make way for palm tree plantations, resulting in tons of CO2 emissions, destroying wild natural habitats, and causing massive biodiversity loss.

Most liquid shampoos you can find today are not eco-friendly.

Why should you switch to shampoo bars?

One of the most commonly asked questions regarding this topic is, “Are shampoo bars better than shampoo?”

Making the switch to shampoo bars is an excellent first step for anyone planning to live a zero waste lifestyle.

First, most shampoo bars today come in plastic-free packaging – no further explanation is required here.

Secondly, many shampoo bars act like shampoo and conditioner as one. Some can even be used as body soap or beard cleaning essential.

The less product you use, the better for the environment because it means less waste, less carbon footprint, and fewer resources consumed.

Do I need to use a conditioner with a shampoo bar?

Most of the zero waste shampoo bars on this list claim that you don’t need a conditioner when using them.

But it highly depends on your hair type and what product you are using.

Can shampoo bars cause hair loss?

According to Medical News Today, hair loss’s top causes include genetics, diseases, and taking medications. Washing your hair with shampoo and conditioner isn’t one of them.

However, shampoo ingredients that can cause irritations such as SLS might strip your hair of natural oils or leave a dry, itchy scalp, hence, encouraging hair loss. (source)

Moreover, artificial dyes and fragrances can also irritate sensitive scalps.

So when shopping for shampoo bars, it’s best to avoid products that contain known irritants like SLS and artificial ingredients.

Also, every person’s hair is different. Keep an eye on your shampoo bar ingredients and pay attention to which can cause hair loss in your personal experience.

How often should you wash your hair with a shampoo bar?

When it comes to taking care of our hair, every person differs from another. We each have different needs, and for that reason, we can’t tell you what is right for you.

So instead, let us ask you a question. 

Why do you shampoo your hair? Isn’t it to clean our scalp from dirt and sebum build-up?

Then, it’s totally up to you when you feel the need to shampoo your hair. Every other day, once a week, once a month, it’s up to you.

However, shampooing every day and exposing your hair to foreign chemicals might strip your hair of natural oils, leaving it dry and brittle.

Fortunately, most zero waste shampoo and conditioner bars on this list are made of natural ingredients. They are also infused with vitamins and minerals to strengthen and promote healthy hair growth.

Nonetheless, how often you shampoo your hair is something only you can answer.

Why does your hair feel waxy after using a shampoo bar? Do shampoo bars make hair greasy?

There are many explanations for why a person’s hair feels waxy after using a shampoo bar.

Others say that it’s because the scalp rebalances the pH and oil production in your hair (aka transition period), while others blame the ingredients present in the shampoo bar.

However, one of the most plausible explanations is that many shampoo bars are made with different mixing oils such as coconut oil and olive oil.

So if you’re using hard water when washing your hair, the shampoo bar oil molecules can bind into the minerals in the water and will leave waxy deposits in your hair. 

This is unlikely to happen if you’re using soft water instead.

But if you’re using soft water and the issue remains, then it could also be that the ingredients on your current shampoo bar are not suitable for your hair type.

  1. Too many have no clue that fast hair growth shampoos (obviously with no sulfates, no parabens and no DEA) even exist. People can now possess longer hair and experience more possibilities. Certainly worth researching.

    If you’re going over alopecia, damaged hair, preventing scalp disorders, hair growth, hair and scalp health at large, almost the same ideas apply.

    Generally, you have to stay away from hair products and treatments that include chemicals such as parabens, DEA and sulfates.

    What is healthy for your hair is healthy for your skin as well.

    It goes without saying your content above hits the nail in the head for various reasons. It stays away from the common errors and traps too many fall into- purchasing defective alternatives. Thank you so much!
