Zero Waste Shampoo: 7 Options to Go Plastic Free

You don’t need to use liquid shampoo in plastic bottles to have a clean, itch-free scalp. Nope! You do not. Try these zero waste shampoo options instead.

Zero waste shampoo typically comes in the form of a bar, wrapped in paper packaging. This eliminates plastic bottle waste. Aloe vera and soap nuts can also be used to make DIY, eco friendly shampoo.

But you should know you may need to try a few types to find the right fit for your hair because – let’s be real – everyone’s hair reacts differently to the same shampoo.

So, have an open mind as you venture into the world of zero waste shampoo.

Why use zero waste shampoo?

Shampoo today likely comes in a sturdy plastic bottle, right?

That’s a problem because plastic doesn’t degrade or decompose. It just breaks up into more plastic.

Yes, you can recycle the bottle if there are good recycling initiatives in your area.

But, recycling plastic just means making MORE plastic.

Recycling doesn’t change it into a material that is safer for the environment.

So, it’s time to switch to better, more sustainable packaging.

The thing is, though, packaging isn’t the only problematic thing about regular shampoo.

Some brands test on animals. They are not committed to being cruelty-free.

Then, there are the ingredients in shampoo.

Parabens are antimicrobial compounds used in cosmetics like shampoo. There is some debate as to whether or not parabens disrupt the endocrine system and cause cancer.

But, there is no debate on what parabens do when they hit the wastewater treatment plant.

They react with chlorine to form pollutants that can affect ecosystems. If the water or sludge is reused, the compounds could be hazardous to us too.

Another problematic ingredient in shampoo is palm oil.

I urge you to read this article from the World Wildlife Fund (WWF). It explains how forests are being cut down to plant palm trees to make the oil.

There is no excuse for deforestation of this magnitude.

So, avoid products made with palm oil – including shampoo. 

Although there are other problematic ingredients, I’ll stop here. Check your labels and research the ingredients. You may be surprised what you are putting on your body.

What to look for when buying zero waste shampoo?

  • Packaging: It is important to purchase products in sustainable and recyclable packaging. Paper based packaging are often biodegradable and metal is infinitely recyclable.
  • Ingredients: Palm oil, parabens, and sulfates are problematic. When shopping for shampoo, always research the ingredients. Use products with natural compounds where possible.

When you order, you receive aluminum refillable bottles of products with plastic pumps and plastic lids.

But, when you’re running low, they send you a new refillable bottle. And, when you’re done with the first bottle, you switch the plastic pump to your new bottle and return the old one too them with the old plastic lid.

Guess what? They cover the shipping cost to send the bottle back! How great is that?

The conditioner contains similar ingredients along with shea and mango butters and jojoba oil.

6. Soap Nuts as a Zero Waste Shampoo

Soap berries or soap nuts come from certain tropical trees of the lychee family. The interesting thing about them are they contain saponins which are natural detergents. They’ve been used for thousands of years by ancient Asians.

You can use soap nuts as shampoo, body wash, laundry soap, and dishwashing detergent. Yep they are very versatile.

Pick up your soap nuts from Eco Nuts – they come in cotton bags within a cardboard box. No plastic packaging here.

Soap nuts make great zero waste shampoo

Check out this Youtube video from We.Are.Wellness. Pia explains how easy it is to make soap nut shampoo.

7. Aloe Vera

I talked about gardening as an eco friendly self care idea.

There, I suggest getting aloe vera plants. They have so many uses and will fit perfectly into your zero waste lifestyle.

As for its use as a zero waste shampoo, all you need is the aloe vera gel. That’s it.

I did a super simple video on how to make the gel.

When you’re done with that, check out Priscilla’s Youtube video on the steps to make the shampoo.

I hope you try these zero waste shampoo options. But, you should know, there are many, many other brands too. Lush has incredibly popular options.

Have you ever tried any of these? I’d love to hear about what works for you.
