As a guy, I've always appreciated a bar of soap that is on the harder side as I like to soap up with the bar itself in the shower instead of using a wash cloth. Having a fair amount of body hair on my legs, soft bars can simple wear out too easy. I've read salt can help with "hardness". But I've seen some recipes rate high on "longevity". What is longevity versus hardness? Any general advice with how to make a good shower bar of soap that will last for a moderately hairy guy?
Thanks
