Best Conditioner Bars of 2021 and How to Use Them

Conditioner bars are an important part of every zero waste bathroom. They’re a great way to ditch those wasteful plastic bottles and still have soft and shiny hair.

However, just like you’ll find a variety of shampoo bars out there, you’ll also find a number of conditioner bars. So how do you know which conditioner bar is right for your hair?

I gathered all of my friends and family with all of their different hair types and asked them to try out different conditioner bars. I then complied their feedback into this list of the best conditioner bars.

How to Use a Conditioner Bar

There are two ways you can use a conditioner bar.

First, you can run the conditioner bar directly over your hair. Then use your hands to rub the conditioner into your hair and scalp. Wait a few minutes, and then make sure you rinse thoroughly to get all of the conditioner out of your hair.

You can also rub the conditioner bar between your hands to create a lather. Then, run your hands through your hair to apply the conditioner. Once again, make sure you rinse well.

If you find that your hair feels heavy or weighed down after using a conditioner bar, skip applying it all over your hair and simply use it on the ends and the driest parts of your hair.

1. Etee Concentrated Conditioner

I have thick, curly hair, and this Etee concentrated conditioner is the bar I personally use to tame my frizz and keep my curls soft.

I pair this conditioner with Etee’s shampoo bar, which I personally think is one of the best shampoo bars out there. If you’ve tried shampoo bars before and feel like they leave your hair weighed down, I highly recommend trying Etee’s shampoo bar. It leaves my curly hair feeling clean and refreshed!

Like the shampoo bar, the conditioner bar was developed with the same chemistry as liquid conditioners. That means it detangles and moisturizes your hair without weighing it down.

I even had some of my friends with fine, straight hair tell me this is the conditioner bar they liked the most. As an added bonus, it also smells fantastic!

This conditioner bar contains no sulphates, parabens, harsh chemicals, or plastic of any kind. It’s also not tested on animals.

If you do any type of traveling, I also recommend picking up one of these soap storage tins to hold your conditioner bar. They do a great job of keeping things nice and neat when you’re on the go!
