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

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. 

Ammonium Chloride

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. They are generally made with synthetic chemicals via a heavy industrial process.

This is why natural fragrances, including vegan 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.

Eco friendly alternatives to plastic packaging for shampoo is to use:

  • Recycled plastic
  • Refillable bottles
  • Plant-based tubes
  • Zero waste bars
