I havent tried it yet but its the best i've come up with so far for liquid soap shampoo.
ive been using 1 part water 1 part dr. bronners for the last few months
I used lavender, cedarwood, and rosemany essential oils. (not much, you can barely smell anything).
This is a very nice bar that works well for everyone in our family. My husband has oily hair, while mine is dry. This works well for both of us- cleans well without stripping my dry hair. It's got nice creamy bubbly lather, and is very mild.
