A few weeks ago, my friend Kathryn sent me a homemade shampoo bar, with the instructions that it could be used as shaving cream if it didn’t work with my hair. My hair has been too dry to have luck with it, but I’ve loved using it as a simple, low-fuss shaving cream. And, can you believe she made it herself?! With just three ingredients, it looks totally replicable. If you've been searching for a zero waste hair or shaving solution yourself, you can find her tutorial here.
