As for me, I once thought I had a somewhat oily scalp and an oily face, used lots of oil-absorbing lotions and such, despite that my face also had dry skin. When I stopped treating it with drying substances and moisturized more, the oiliness of my combination face settled way down. Similarly, when I switched to CO washing, I went from having to was my hair every day or two to being able to wash roughly every 5 days. So my face has combination skin and my scalp is reactive.
