Shampoo Bars: A Guide to Ethical & Sustainable Shampoo

Table of Contents

An Introduction: Shampoo Bars and The Sustainability of Hair Care

Most of what we do involves some sort of product and purchase, and while consumption is ingrained in our lives, if doesn’t have to be mindless. Big change requires big companies to take systematic action, but every consumer has the opportunity to vote with their wallet for concerns they want corporations to take into account. And if we spend time asking questions about the ethics and sustainability of products before we buy them, we’re putting our money on the positive changes we want to see in the world.

This is the essence of the conscious consumerism movement; to think before we buy, use, and throw away.

And, as 73% of global consumers say they would change their consumption habits to reduce their eco-impact, consumer concerns are evidently shifting.

One thing we do every day that could benefit from more eco-thinking is our shower: the amount of water we use, the harmful chemical compounds in our products, not to mention the plastic packaging, all of which contribute to our environmental impact. Luckily, a recent trend has entered the eco-living sphere ready to change the showering game: ethical and sustainable shampoo.

Enter The Shampoo Bar

You may have seen new brands enter the market, with ‘eco’ and ‘cruelty free’ prominently displayed on their packaging, and old brands taking a proactive approach to acknowledging and changing their wasteful practices as buyers change their shopping demands. And even better than their bottled counterparts, solid shampoo bars are increasingly cropping up and transforming the hair-care scene.

These zero-waste, travel-friendly, space-saving, and long-lasting bars are perfect for keeping both your hair and conscience clean.

But, while it all sounds too good to be true, it’s important not to be caught out. Often these products are expensive, their effectiveness is debated, and they’re not as ethical as they claim to be. They’re culprits of ‘Green Washing’: marketing used to attract customers with unsubstantiated and misleading claims. As we become more and more bombarded with labels, slogans, and expensive items, it’s important to know what’s worth spending our money on.

Are Shampoo Bars More Eco Friendly?

Shampoo bars are not only a much cheaper option, they are also undeniably more environmentally friendly. This is especially true since they’re highly concentrated, so you’re not paying for anything watered-down and can get more uses out of them!

Knowing that the bars themselves are zero waste, and the paper packaging is 100% recyclable, can give you peace of mind on the packaging front too. Shampoo bar companies also have a tendency to be much more transparent about the ethics of their products, with simpler ingredient lists, charitable policies, and clearly displayed certifications.

Shampoo Bars vs Shampoo Bottles

If you’re unsure whether a shampoo bar will work for you, you can always try turning it into a liquid and use it in a way you’re more familiar with. All you need to do is to put in a jug or bowl and pour boiling water over it, stir until it full dissolves, and transfer into a bottle an old shampoo bottle, or a drink bottle you’d otherwise throw out. This is a great way to reduce waste and reuse what you already have.

The downside, however, is that the shampoo bars are much less diverse and specialised for different types of hair. But, as with any products, as they become more and more popular, their effectiveness will be improved and hopefully we’ll see some more bars emerge suited to different hair types. The only way for this to happen is to increase their demand and for more people to start making the switch!

What Does Eco Friendly Shampoo Mean?

For a product to be ethical it must not be produced in way that is harmful to society, animals, or the environment. This could mean ensuring that workers producing the ingredients are paid fairly, it is not tested on animals, and is not harmful for the earth. Ethical products are, essentially, kind to people and the planet.

‘Sustainable’ is a narrower term, and in its simplest definition means ‘the ability to be maintained at a certain rate or level’. In other words, product’s environmental impact over its whole life cycle results in minimal, or ideally no, waste or destruction. Sustainable products environmental conscience covers their production, use, and disposal.

Below are some key things you can look out for when deciding whether the shampoo you’re buying is ethical and sustainable, so check the labels carefully!

Cruelty-Free and Vegan

Cruelty-free is the label given to products that are not tested on animals in any country in the world. This is different to vegan products, which, as well as not being tested on animals, do not include any ingredients derived from animals. Now you may be thinking what animal-ingredients are being put into the product in the first place, but you’d be surprised! Like many cosmetics, ingredients such as beeswax, honey, and milk are often snuck into shampoos.

Using vegan and cruelty-free products ensures no animals were harmed in the process and the ingredients are more likely to be natural. Vegan packaging is also more frequently recyclable and environmentally friendly.

To avoid misleading packaging, you can check for PETA’s cruelty-free and vegan logo:

Palm-Oil Free

Palm oil has become almost a curse word in the world of ethical consumerism; when you see it alarm bells should ring. The palm oil industry is a major driver of deforestation, destroying habitats of endangered species, contributing to climate change, and, in some cases, exploiting workers and abusing child labour.

Check the ingredients list to see whether the shampoo is palm-oil free, and be cautious of ‘sustainable palm oil’; according to Green Peace it is often simply a way for companies to continue using the ingredient, destroying forests, and getting away with it!

Non-Toxic and Natural Ingredients

Have you ever read the ingredients list on a shampoo bottle and felt like you’re reading a language from a sci-fi film? The ‘non-GMO’, ‘paraben-free’, ‘sulfate-free’, and ‘SLS-free’ talk is equally confusing. So how do we trust what’s going on our hair, and into the planet, when we can’t even understand it?

This is a tricky one, but there are ways around it without needing a post-grad chemistry degree. A good place to start is to go for organic (see our breakdown of exactly what organic means) and natural products as an easy way to avoid artificial chemicals used in shampoos (and an added bonus – it’s also better for our wellbeing to avoid synthetic chemicals!). You can also check that they’re certified as organic by looking out for logos like the Soil Association one below.

The downside, however, is that ‘organic’ often equates to expensive, and is popular in greenwashing, so understanding ingredients is even more useful (here is a great guide to help you out!).

Fairtrade

Fairtrade considers every person involved in the production and selling of the product; a fair-trade policy helps ensure the wellbeing of marginalised small producers and that farmers in developing countries can compete in the global economy. There are formalised fair-trade certifications such as Fairtrade international (FLO), and it’s always good to look out for their green and blue logo on the packaging.

fairtrade logo

Many companies, however, see it as favourable (and actually more ethical) to have their own Fairtrade policy. This is because many ingredients may be locally produced, and it allows for the company to work closely with the producers and have a more direct relationship with them. There may even be a mixture of certified Fairtrade and local direct trade ingredients used in one product, and so the company’s website is a good place to look for their Fairtrade policy and can tell you if they are ensuring their suppliers’ working conditions are dignified and fair.

Packaging

Most shampoos, even the best organic shampoos, come in non-recyclable plastic bottles which, alongside food packaging, plastic bags, water bottles and so many other things we regularly use or consume, contribute to plastic pollution. When we throw away plastic bottles, they end up in the oceans, injuring sea life, or breaking down into equally damaging tiny particles called microplastics which enter the food cycle.

If you’re not ready to go try a zero-waste shampoo bar, then try to opt for recyclable bottles and thoughtful packaging instead; shampoo refill options are also becoming increasingly available!

Final Thoughts on Sustainable Hair Care and Shampoo Bars

The sustainability movement frequently comes under the charge of elitism, and whilst we’ve looked at products varying in price in this guide, it’s evident there’s a market for cheaper, more accessible options (which don’t require the leisure time for a Sherlock Holmes level analysis of the ingredient lists!). Hopefully these are on their way in the not-so-distant future…

  1. Really interesting Heather, thanks for opening my eyes on this. I’ve just bought some Faith in Nature products based on your recommendation here 😊 I think it would be really useful to have a similar article for laudry detergent and fabric softener too. It’s a great point about it being elitist as these do seem really expensive. It would be awesome to have a quick reference table where you can see the cost per 100ml (or something similar) for each product, to enable a direct comparison. I found myself thinking some were hugely expensive before I realised they were just bigger bottles! Anyway, great article and thanks for sharing.

    • Thanks for the amazing feedback and the suggestion, Jen! I’ve added the approximate price per 100ml to each of the bottle listings.
