KinKind
KinKind is my go-to because they’re the UK’s first fully dedicated solid haircare brand, and they’ve kept everything vegan, cruelty-free, and plastic-free from the start. Each shampoo bar lasts up to 50 washes, replacing two plastic bottles, and they have specific formulas for curly, coloured, fine, or sensitive hair. They’ve won awards like Pure Beauty Global and Indy Best, proving they’re not just eco but effective.

Faith in Nature
Faith in Nature has been a vegan brand for decades, and their shampoo bars are one of the most accessible and affordable options in the UK. They come in simple scents like lavender or coconut and are widely stocked in health shops and online. A great starter bar if you’re new to the switch.
Ethique
Originally from New Zealand, Ethique’s shampoo bars are now available in the UK. They’re one of the most eco-committed brands, going beyond plastic-free to offset carbon and donate profits. Their vegan shampoo bars cater to different hair needs, and the packaging is fully compostable.
Lush
Lush might be best known for bath bombs, but their solid shampoo bars are some of the most popular in the UK. Most are vegan, they lather easily, and each one has a signature scent. They’re easy to pick up on the high street, though not always the cheapest.
Friendly Soap
Friendly Soap make handmade vegan shampoo bars in Yorkshire, using traditional methods. They’re very budget-friendly, with simple natural ingredients and recyclable packaging. A great choice if you want something low-cost and minimal.
Beauty Kubes
Beauty Kubes are a little different: instead of a bar, you break off a cube of concentrated vegan shampoo and lather it up with water. They’re completely plastic-free and ideal for travel, though slightly pricier per wash compared to a solid bar.
Conclusion
If you want a shampoo bar that’s vegan, effective, and made in the UK, KinKind is the one to beat. They’re award-winning, designed for different hair types, and replace multiple plastic bottles. Whether you start with KinKind or try one of the other options here, making the switch to a vegan shampoo bar is one of the simplest eco upgrades you can make in 2025.
