    OMIT the hydrogenated vegetable oil & the coconut oil. You could use those for cooking/baking instead, IF you’ve already purchased them. Why put oils (or fats) on your hair when the entire point of WASHING your hair is to REMOVE your own sebum & the dirt attached to it, right? You would be sadly wasting those ingredients and the money you spent on them if you put them in your shampoo bars. You do NOT have to “follow the crowd” if they’re doing something that does NOT make sense.
