Chagrin Valley is a family-owned soap company based in northeastern Ohio. While they no longer make soaps out of their kitchen, they're still as committed to all-natural, GMO- and synthetics-free skincare as they were back in 2001. This is a concentrated organic apple cider vinegar hair rinse, designed for clarifying your hair post-shampoo. It's infused with certified organic herbs and organic tea tree oil, rosemary, spearmint, peppermint and lime essential oils. Unlike a lot of hair rinses, the first ingredient here is pure concentrated vinegar, so CV recommends using their plastic squeeze bottle to measure and mix with water, so you can dial in your perfect proportion.
