I was introduced to shampoo bars a while back and really liked the idea. If you haven’t tried them before, you can buy shampoo bars on Amazon.

Since they’re solid, they have a longer shelf life than liquid shampoos. They’re easy to make and they’re easy to bring along on vacation too. Plus shampoo bars work great!

I’ve had several people ask if you need to include the cetyl alcohol. I understand it’s not a common DIY beauty ingredient, so you may not have it on hand. It is absolutely necessary to use it. It’s what binds everything together and makes it work. So don’t omit it!

I have chosen to use a few essential oils that have great benefits for hair and most people have on hand. If you want to switch it up, you can check out the post I wrote on essential oils for hair for some more ideas.
