I know what you mean. My niece's hair does that with braids in and my sister tries to wrap a silk scarf around her head at night, but you know kids sleep wild, so it's always off the next morning
I can get it braided cheap, so the money isn't an issue. But I want to keep it up for at least 6 months to a year and I don't want my edges all jacked up. Like Curlilocs said, maybe if I just keep it well moisturized it will be ok. I have been slicking my hair back in buns and ponytails all my life and my edges are ok, so maybe braids won't hurt either. At least I am hoping.
