A solid shampoo bar that lathers reasonably and lasts well with very little packaging. It can feel drying on some hair and needs a dish to dry between uses, but it has replaced bottled shampoo for us.

What works

  • Eco-friendly
  • Made with natural ingredients
  • Ethical and cruelty free

Watch out for

  • Difficult to store
  • Less lather than conventional shampoo

Bid farewell to plastic bottles and embrace a greener hair care routine with the Eco Warrior solid shampoo bars. Not only are these bars environmentally friendly, but they are also enriched with natural ingredients that will leave your hair silky and nourished. Unfortunately, this brand may not be easily accessible in the US, but don’t worry. There are other amazing options available that you can explore.

Here’s my unbiased review of the Eco-Warrior shampoo bar. I have put it to the test, so you don’t have to, and I will compare it to conventional shampoos in plastic bottles to see if it stands up.

My Honest Review of Eco Warrior Shampoo Bar

The shampoo bars promote healthy hair and infused with the refreshing scents of orange and ginger essential oils. It is made in the UK by the Little Soap Company, a B-Corp corporation, and comes with entirely plastic-free packaging.

The bar is made with 94.3% naturally derived ingredients and uses certified sustainable palm oil. It has earned numerous beauty awards and is 100% vegan and cruelty-free. Its Yuka score is an impressive 86%, indicating its high-quality ingredients and safety.

Eco Warrior Shampoo Bar vs Conventional Shampoo

Shampoo bars are solid, eco-friendly, and made with natural ingredients for healthy hair. It is a more sustainable option for those looking to reduce their environmental impact.

On the other hand, conventional shampoos in plastic bottles are often formulated with a broader range of chemicals and synthetic ingredients and generate a significant amount of plastic waste.

By choosing to use low waste products and avoiding unnecessary plastics use, you are taking a step towards a more sustainable lifestyle and reducing your environmental impact.

Why I Love the Eco-Warrior Shampoo Bar

When choosing a good shampoo, I focus on three critical criteria: lather, cleanliness, and how moisturising it is.

Using a solid bar is simple, just rub the wet soap directly on your wet hair. One thing to remember when using eco-friendly shampoo bars is that they often require a double wash. This means washing your hair twice, the first to remove oils and the second to cleanse away dirt.

I found that the bar lathers well in the second wash, as shown in the picture of me using it. After using it, my hair and scalp felt clean and refreshed. However, I recommend using a conditioner afterward as the bar can be a bit drying.

How to Store Shampoo Bar?

The best way to store a solid bar is in a dry and airy place, away from direct moisture. This will prevent the bar from melting or becoming mushy, ensuring it lasts longer. Some options for storing shampoo bars include:

  1. Bar holder or dish: A holder or dish with good drainage can keep the bar elevated and allow it to dry completely between uses.
  2. Soap saver bag: A soap-saver bag made of natural fibers like cotton or hemp can keep the bar dry and prevent it from slipping away while in use.
  3. Dry and ventilated location: Store the shampoo bar in a dry, ventilated area where air can circulate freely, such as a bathroom shelf or soap dish.

Are they worth it?

Although they can be a bit drying and not as moisturising as conventional shampoos, I still choose to use them over the ones in plastic bottles.

A little bit of conditioner and hair oil helps with the dryness, but what I love about shampoo bars is how fresh, and clean my hair and scalp feel afterward.

Despite the slight downsides, the benefits of using shampoo bars make it worth it and I don’t plan on returning to using traditional shampoos anytime soon!
