What you put on your body is as important as what you put in your body. Your skin is porous, therefore what you put on your skin is absorbed into your body (that's why nicotine patches work). Making your own personal care products is one way to give your body a break from unnecessary chemicals. I've also included some sources for buying safe products if you don't want to make your own.
One word of caution, your homemade product is only as good as the ingredients you use. Shop carefully or grow your own.
