It's not that the hair gets damaged from occasional braids left in for a while, it's that the braids get "fuzzy" and start to look messy. My daughter's 3c hair looks fuzzy within a week and at 70 bucks a pop, it gets very expensive. Yours would last longer because you can sleep with your hair covered and take better care of them than a little girl.
