The 9 Best Conditioner Bars of 2023

Our top choice for most hair types is EcoRoot's Moroccan oil conditioner bar.

We independently evaluate all recommended products and services. If you click on links we provide, we may receive compensation. Learn more.

If you're looking to make the switch to shampoo bars, you may also want to add conditioner into the mix. Conditioner bars go hand in hand with shampoo bars and come in many varieties for all hair types. Besides being good for your hair, conditioner bars are cost effective, typically lasting much longer than a typical bottle of liquid conditioner. Bar shampoos and conditioners tend to be better for climate change too, because they weigh less and use less energy to ship than liquid hair products.

Currently, about 8 million metric tons of plastics end up in the ocean every year. Conditioner bars help reduce plastic waste, because many come in recycled paper, eco-friendly paper boxes, or even package-free. Conditioner bars are also great for travel, as you don’t have to worry about exceeding the liquid-ounces limit or a leaky bottle.

Check out our suggestions for the best conditioner bars below, all of which are made with natural, safe ingredients.

Surprisingly, one of the best natural treatments for dandruff is beer. Due to its high vitamin B and yeast content, beer helps hair become bouncy, shiny, voluminous, and flake-free. Beauty and the Bees is raising a glass–er, a bar–to this with its beer conditioner bar.

Using beer brewed naturally from small breweries in Tasmania, Australia, this conditioner bar moisturizes and conditions without leaving hair heavy. Leatherwood beeswax, honey, mango butter, and Tasmanian hop-infused certified-organic raw coconut oil provide nourishing essential oils as well, leaving hair full of bounce without weighing it down.

One caveat: If you're a vegan who chooses not to use beeswax or honey, this product is not for you.
