First, our regular soaps. They are made with Lard, Coconut oil, and Olive oil. This combination creates a soap that is hard and long lasting, cleansing, creamy and sudsy. It's a great hand and body soap. Sometimes we add herbs to it, or light abrasives like coffee grounds or pumice.
Shampoo soap is made with different oils. They are Olive oil, coconut oil, and castor oil. This makes slightly softer soap that needs to dry longer before it can be used. It is also very sudsy. The castor oil is conditioning so you don't need to use extra conditioner on your hair.
How do you use shampoo soap? It seems odd, but you just wet down your hair and rub the bar on it. Then set down the bar and suds up your hair. Rinse and you are done! You can repeat if your hair is dirty or you have a lot of it. Unlike commercial shampoos, shampoo soap doesn't strip the natural oils from your hair, making your scalp produce more oil and making your hair look greasy soon after washing. Many people can skip a day or three of washing their hair, making shampoo bars great for camping! They are also great for travel, especially plane and overseas travel where containers are a concern.
