Remember a client brought in homemade "activated charcoal" toothpaste that stained my sink permanently. They meant well trying to avoid chemicals, but cleanup was a nightmare. Some things are just better left to the pros with tested stuff lol.
Homemade beauty stuff always ends in stains or messes. A client once used a DIY avocado mask that left oil rings on my towels for weeks. Good intentions don't always make up for the cleanup job.
