A quick and easy recipe for homemade shampoo starts with pure soap flakes. Grated Ivory brand soap works just as good if you can’t find the flakes in your store. Boil one and a half cups of water and steep four chamomile tea bags for ten minutes. Remove the bags and add the soap flakes. Let the mixture rest so the soap with soften and dissolve. Add one and a half tablespoons of glycerin and blend until smooth.
