Shampoo bars are a straightforward swap for anyone looking to make their self-care routine more sustainable. These bars are often package-free when you shop in person or come wrapped in easily recyclable or compostable paper packaging, which reduces the amount of single-use plastic in your life compared to a plastic bottle of shampoo.

Of course, not all hair types are the same, and neither are all shampoo bars, so Treehugger has put our first-hand experience and research chops to task to help you find the best bar for you. We reviewed every ingredient to make sure all our recommendations are vegan, never tested on animals, and paraben-free. For some people, the results may actually be better than your current liquid cleanser.

Bar soaps also tend to be associated with fewer planet-heating greenhouse gas emissions compared to liquid bottles of suds because they weigh less due to low water content. For the same reason, bar shampoos will also travel well in your luggage. You won't have to worry about the TSA's liquid limits or any wasteful spills.

Ahead, the best bar shampoos, whether your hair is dry, fine, oily, or curly.

Best Overall

Lush Cosmetics Montalbano Shampoo Bar

Shampoo Bar Montalbano


The Montalbano bar has become part of my daily morning routine and can be used without conditioner. It’s great for regular-to-oily hair types, and the citrus scent is a perfect wake-me-up. The vegan formula includes rosemary and green olives for added shine.

Lush’s shampoo bars are beloved by many Treehugger staffers, but the best one for you depends on your hair type. One of Lush's bars can replace up to three 250 milliliter bottles of liquid shampoo. If you shop in person you can get it with zero packaging, or if you order online, Lush shampoo bars usually come packaged in a small paper bag.

Ethique Heali Kiwi Shampoo for Dandruff or Scalp Problems

Ethique Dandruff Shampoo Bar


Treehugger writer Katherine Martinko took a number of Ethique's products for a spin and found that these shampoo bars deliver effective cleaning in plastic-free packaging. If you suffer from an itchy or easily irritated scalp, then the Heali Kiwi shampoo bar may be right for you.

This bar is formulated with calming oatmeal, coconut oil, neem oil, and karanja oil to help soothe scalp issues as well as dandruff. As the name would suggest, it has a fruity fragrance. Ethique also donates a portion of its profits to environmental charities.

The featured ingredients include African dates and Vitamin B5. It’s free of sulfates, silicone, and phthalates, and it’s safe for color-treated hair.

It feels and lathers a lot like your typical bar of milled soap. It's Leaping Bunny certified, meaning it's animal-testing free, in addition to being vegan and free of palm oil.

Frequently Asked Questions
  • How do you use a shampoo bar?

    There are two approaches to using a shampoo bar. One option is to gently massage the bar over your wet hair and scalp until a lather forms. The second option is wet the bar and work up a lather in your hands, then apply the suds to your hair.

    In either case, it's a good idea to store your shampoo bar in a dry spot when you're done using it, to help it last much longer.
