Don't just blindly whip up a hair butter and start using it for your body too. You should investigate whether the butters, carrier oils and essential oils that you are using are the best ones for skin.
Remember that hair is dead matter and skin is living so you will feel the differences in oils a lot more on your skin than you would on hair.
Whenever I get a new oil I run it over my skin to see how well it absorbs, how thin or thick it is, how greasy and so on and sometimes I get surprised.
For instance, I was surprised that apricot oil seems to just glide over my skin without being soaked in. And I was even more surprised at how well baobab oil was absorbed by skin - we have lots of baobab trees in Malawi (my country of origin) and when you see one of those menacing trees you would never imagine how moisturizing its oil is.
