5 Best Eco-Friendly Shampoos for a Sustainable Wash

best eco friendly shampoos

When was the last time you had a look at the ingredients label of your go-to shampoo?

The sheer number of ingredients is quite scary isn’t it?! 

Some of us spend a lot of money and time looking for the perfect hair products for our hair type, while others are more than happy using the same store-brand product without thinking twice.

Whether you’re a haircare enthusiast or just want to keep it clean, the shampoo you use could be impacting the environment.

Here’s all you need to know about the environmental impact of conventional shampoo and where to find the best eco-friendly shampoo in the UK!

What is the issue with conventional shampoo?

First things first, let’s take a look at how most conventional shampoo is made, and what makes a lot of name-brand shampoo unsustainable.

Shampoo is usually made by combining a number of ingredients:

  • Type of surfactant
  • Chemical compound that reduces the surface tension of liquid
  • Moisturising agents 
  • Other water-based ingredients

Not all shampoos boast the same properties. And while this basic formula is the blueprint for most cleansing shampoos, different types offer different benefits, such as UV protection, dandruff control and colour protection.

These different properties will change what chemicals are involved in the process, but you’re likely to always find the same base ingredients: 

  • Sodium laureth/lauryl sulfate
  • Parabens
  • Phthalates
  • Ammonium chloride
  • Fragrances

Are these chemicals sustainable?

Theoretically speaking, both sodium lauryl sulfate and sodium laureth sulfate (often shortened to SLS and SLeS) are considered toxic to marine life. This is becuase sulfates have been found to acidify surface water, turning into sulfuric acid.

However, the SLS and SLeS used in shampoo are highly biodegradable!

The real issue with sulfates is how they are sourced. According to a WWF report, many shampoo manufacturers derive their sulfates from palm oil, one of the most destructive crops for biodiversity and a major driver of deforestation.

When not derived from plant-based ingredients, sulfates are commonly petroleum-based instead, which does little to help reduce CO2 emissions.

Parabens and phthalates, on the other hand, do not naturally degrade in the environment as easily. Increasing levels of parabens and phthalates have been found in surface water and sediments.

Both chemicals are associated with endocrine disruption in both human and animal life, with phthalates even being a classed carcinogen. Not good. 

Finally, both the ammonium chloride and synthetic fragrances you’re likely to find in conventional shampoo are believed to be toxic to aquatic life

These substances have been found to promote excessive algae growth and biological disorders in aquatic environments, leading to habitat disruption.

Any sort of fragrance is usually bad news for the environment, which is why vegan and eco friendly perfumes are on the rise.

What about shampoo packaging?

In addition to the harmful chemicals and unsustainable sourcing practices, conventional shampoo also comes in plastic bottles. 

Even though these plastic bottles are recyclable, they still contribute to carbon emissions.

Some even come in the foil-plastic packaging which are very difficult to recycle.


5 best UK eco-friendly shampoo brands

Thankfully, there are now plenty of paraben-free, sulfate-free, and plastic-free shampoos you can choose from! 

Eco-friendly shampoo brands are getting more popular all over the UK. So whether you’re simply looking for plastic-free shampoo packaging or fully going green with zero waste, all-natural shampoo bars, you’re guaranteed to find something that works for your hair and the planet too!

1. Faith In Nature

If you’re looking for affordable eco-friendly shampoo, Faith In Nature has you covered with SLS and paraben-free hair products.

The brand’s shampoos and conditioners are also free from chemical fragrances, preservatives, animal products and any petrochemical-based ingredients. All the products for this independent family business are made from their factory in Lancashire.

Faith in Nature’s all-natural haircare products do come in recyclable plastic bottles (sometimes recycled plastic), and refill points are available throughout the UK — just bring your own reusable bottle! You can also buy large 5L refill bottles from their website and send your old bottles back to them.

While bars make for the most sustainable option when it comes to eco shampoos, they’re often a little tricky to use and store due to their shape.
