Soap for your hair?! Yup.
How to use all-natural soap for your hair: Lather soap directly on your hair or in your hand. Rinse. Follow with your normal conditioner or a diluted vinegar rinse (I use a capful of cider vinegar to one cup of water) to leave your hair soft and shining. The first couple of times you use all-natural soap and vinegar in place of shampoo and conditioner, your hair will feel limp and might lie a little flat but that effect will pass. It’s because your hair is used to all that extra build up left by whatever chemicals are in your typical shampoo.
