Shampoo bars are in the top three soaps that I use regularly. I LOVE them! They are portable, simple to use, environmentally friendly (no chemicals, no preservatives) and they last a long time. Sunflower oil is the key to making a great Shampoo Bar. Sunflower oil is light and doesn't coat the shaft of the hair and weigh it down. The Shampoo Bar is great for any time of hair including thin or fine hair. To use, grasp the bar of soap and rub it across your head a few times. Lather and rinse. If you normally utilize a conditioner, follow up with your conditioner of choice. In the summer consider steeping lemon balm and water to make a type of tea. Cool and store in refrigerator. When you need a hair rinse, this is your ticket.
