I've been natural for 10 months now. I decided to have my hair straighten for an upcoming party. My hair was blow dried and then hot combed and then curled. The problem/question is my curls are very soft like, if you run a comb through the hair the hair looses shapes, where as when I was permed I could curl it and that curl would last for serveral days. With my hair being in it's natural state for 10 months does the hair need to be trained to hold curls again?
