Coconut oil is actually drying to the skin when it's in soap, and there are things that you need to do in soapmaking to lessen the drying effects of coconut oil.
We have been told that unless a soap gives you a big fluffy lather - it won't cleanse you properly. This is completely false. We are told this to keep us using soaps made from coconut oil. The industry wants us dried out so we'll use as much moisturizer as possible. They can also tell us "don't use soap on your face" because it's drying, and instead, buy a product to only wash your face with. The industry simply has a vested interest in keeping us dried out, and selling us all these different products for different parts of our body.
The Middle East has used only olive oil in their soaps for countless centuries. There is a reason for this. Nothing compares to the moisturizing capabilities of an all olive oil soap. Add goat milk to the soap, and you have an incredibly moisturizing and skin softening soap that can and should be used in the hair.
