I have a gentleman from my church who wants to try it. But mine is scented so I need to make a sample just for him. He has some sort of skin condition (he didn't explain so I didn't ask) but he likes my soap and says it works better for him than what the doc sells him. So I'm going to whip up some unscented shea for him to try. Can I do 100% or is the consistency better with a liquid oil added? I've been using Sweet Almond but I'm wondering if Sunflower would be better? I really like the feel of Sunflower. I don't have enough jojoba to use that. I do have Grapeseed. What do you think would be best?
