I make my own rosemary grapefruit shampoo that is the best I’ve ever had for my hair. I have fine, flat hair that has some body for the first time in my life. The book I got it from is 200 Tips, Techniques & Recipes for Natural Beauty by Shannon Buck. The main ingredient is Dr. Bronner’s castile soap, which I buy in the largest container they sell. There is also PlaineProducts. They send you shampoo and other products in a container you return. My problem with this is that shipping means trucks and more global warming.
