I work outside and the wind tangles the crap out of my hair so yea its a major factor. I bought a satin pillow case to sleep on and its probally cut the frizz and tangles in half so you could try that, and though my hair isn't long enough (chin length) to pineapple at night I bet it would help a ton. Also I've read satin sleeping caps work well, but I havnt tried those either.
