I started with liquid shampoo recipes that I got from Swift Crafty Monkey (paid subscription) and have since switched to bars. Mostly because I wanted to get rid of the containers. The great thing about formulating your own is you can customize it to your hair. This true of either liquid or bars. As @Misschief mentioned, the Humblebee and Me site is a great place to start for either liquid or bars.Question: I searched for "liquid shampoo recipe" and only found shampoo bars on this forum. Are bars better for hair, than liquid? Or easier to make than liquid? I'd like to make my own shampoo: and just am looking for a place to start. Thank you in advance!
