Coconut Milk Body Wash Mix together a 1/4 cup full fat coconut milk with 1/3 cup liquid castile soap. I love Dr. Bronner’s. You can use lavender scented soap or add essential oils for a relaxing scent. Combine in a squeeze bottle and lather up. The mixture tends to separate a bit after sitting so you might need to shake it up a bit before using. Oh, and this can also be used as shampoo!
