Thanks for all the suggestions and tips.
I have been washing my hair once a week and then using plain old EVOO to oil my roots and length. I oil my length and my roots every other day, or every two days. I'm not big on products (yay!), so I try to keep it to a minimum.
Could my sweating at night have something to do with the dryness? I have a pretty high body temp (I'm normally at about 99.2 - that used to help me a LOT when I didn't want to go to class!), so I usually end up sweating all the time. This is the main reason why I refuse to go natural...I like wearing my hair straight too much to deal with all the stress and drama that goes into flat ironing, pressing and the like. I tried it once before, and hours after getting my hair pressed, it would revert right back. But not all of it. Man, my hair used to look a MESS!
