The 10 best shampoo bars to buy in the UK
Are you looking for an eco-friendly and plastic-free alternative to traditional liquid shampoos? Look no further than the best shampoo bars! Say goodbye to wasteful shampoo bottles and hello to a more sustainable haircare routine with solid shampoos. If you consider making the switch to solid shampoo bars today, then check out the buying guide below for all the info you need to find the best shampoo bar.
What are shampoo bars?
Shampoo bars come in a solid form providing a natural and eco-friendly alternative to liquid shampoos. Without the need for plastic bottles, this shampoo has minimal or plastic-free packaging, making them a great choice for those who are environmentally conscious. The best shampoo bars are available in a variety of formulations, making them suitable for different hair types. So, whether you have dry or oily hair, there is probably the right shampoo bar out there for you.
Why should you buy a good shampoo bar?
Unlike liquid shampoos, shampoo bars don't require plastic bottles, making them an eco-friendly choice. By choosing a shampoo bar, you can significantly reduce your plastic waste and help to protect the environment. The best solid shampoos are also formulated vegan and cruelty-free and have nourishing ingredients like natural oils and botanical extracts that help to strengthen your hair and keep it hydrated throughout the day.
How to choose the right shampoo bar in 2025?
Shopping for the best shampoo bar is not always easy, so here are three things worth considering when buying:
- Ingredients: Look for quality shampoo bars with ingredients that suit your hair type. If you have dry hair, then you should avoid chemical ingredients like sulfates that deplete the hair's natural oils. In this case, a gentle option with aloe vera and shea butter is better-suited.
- Vegan and Cruelty-Free: If you are committed to using products that align with your values, look for a shampoo bar that is vegan and cruelty-free. This means that it neither does contain any animal-derived ingredients nor has it been tested on animals.
- Sustainability: While solid shampoos are generally more eco-friendly than traditional shampoos, consider the packaging the shampoo bar comes in. Consider buying from reputable brands that use plastic-free packaging, which is a more sustainable choice. Additionally, if you are interested in organic and natural shampoo bars, be sure to check also these labels.
