The adjustment period wasn't really nice, and the part about washing my hair mechanically is important - I usually start from the head, my hands get uncomfortably oily, but I'm about to use some washing agent or my body, so it rinses off naturally. On the second "attempt" it is already much better.
Our body naturally regulates head skin/hair environment with oils, but we somehow decided that we know better. It's not unlike some people who overuse face cremes and fuck up their face skin moisture levels, or people who have chronic runny nose because they used vasoconstrictor nasal drops daily and destroyed the system there.
I'm of course not a professional and you shouldn't rely on any of my advices/comments, but really, we are result of evolution, and if you don't have any particular genetic problems or diseases, systems are working "as is" much closer to the optimal state, compared to the case where we try to "fix" them with some stuff.
