A few thoughts ran through my mind.
Do you shower at night and then sleep on your back? Perhaps it is "ruffling" your hair during the night and it isn't bouncing back in the morning.
Other thought- do you think it might have been burned by the hair dryer and just in need of a deep conditioning treatment?
