I want to try to make a batch of shampoo bars. I was wondering what oils some of you have used that didn't leave a sticky film on your hair? The oils I have are olive, jojoba, coconut, palm, sunflower, glycerin, Castor, safflower. I was also thinking about try to use a herbal tea in place of the water. I have some silk that I was going to use as well. I don't know I'm just throwing some ideas around.
