I have tried bonnets (came off during the night) and pineappling (headache) so I gave in about a year ago and go to sleep with my hair half to one quarter wet. I only have to spritz my hair in the morning with water if I go to bed with crunchy hair. I am guaranteed a ponytail day if I go to bed with no crunch because I wake up looking like the Lion King. My schedule doesn't allow me to co-wash in the morning. My alarm goes off at 4:45 for the day
Crunchy hair at night = sometimes nice, soft clumps in the A.M.
