The Best Shampoo Bars for Your Hair

If you’re working toward a zero waste bathroom, one simple switch you can make is ditching that plastic bottle of shampoo for one of the best shampoo bars.

However, just like liquid shampoos, you’ll find an almost overwhelming variety of shampoo bars out there. So how do you know which one is right for you?

I decided to recruit all of my friends and family with all of their different hair types to help you find out which shampoo bar is right for your hair.

Also, if you’re in a hurry and just need to refresh your hair, don’t forget to take a look at our list of the best eco-friendly dry shampoo. You’ll find plenty of great options that use natural ingredients to clean, lift, and revitalize your hair.

The Benefits of Shampoo Bars

Shampoo bars have a lot of great benefits besides making it easier to reduce your plastic use and helping you cut back on waste.

Take a look at that bottle of liquid shampoo and tell me one of the first few ingredients you see. It’s water, isn’t it? Now take a look at the ingredients in a shampoo bar. Guess what ingredient you don’t see? That’s right. Water.

Since shampoo bars are more concentrated and not diluted with water like liquid shampoo, you don’t have to use as much to clean your hair. This is a great way to save money!

Shampoo bars are also incredibly convenient when traveling because you don’t have to worry about leaks or spills. Plus, shampoo bars tend to be more natural and gentler than liquid shampoo.

Best of all, you’ll notice that many of these shampoo bars come from some of the top zero waste online shops. That means you know you’re making a truly sustainable choice and eliminating all types of excess plastic from your life.

Now that you know some of the benefits of using shampoo bars, you can choose one of these best shampoo bars for your hair type.

1. Best Shampoo Bars for Curly Hair

I have curly hair, so I understand the struggle of finding a shampoo that cleanses but won’t cause too much dryness. This concentrated shampoo bar from Etee is the one that works the best for my hair. It also received rave reviews from friends and family who have fine, straight hair!

If you’ve tried switching to a shampoo bar before and felt like it left your hair weighed down with residue, you definitely want to try this shampoo bar. It was developed using the same chemistry as liquid shampoo, which means it cleanses and nourishes hair without weighing it down.

It’s also made with 100% plant-based ingredients and has a calming lavender and chamomile scent.

If you decide to get this shampoo bar, don’t forget to pick up one of these soap storage tins. They’re great for protecting your bars from water in the shower and for storing your bars when you’re traveling.

Etee also makes a concentrated conditioner bar that works just as well as the shampoo bar. So you can clean your hair and leave it smooth and nourished without any wasteful plastic!
