Hmm. Can tell you parts of my hair are highly porous and sleeping doesn't seem to affect any of my hair much, if at all. Pineapples do work for me, though I don't see them as a necessity. I just do them when I want that "polished" look from day to day. Sounds like you've been spared the awkward feeling pineapples give. I really don't like that feeling of hair being bound up and my head feeling a little heavy lol
