My hair has reached shoulder length when dry (woot woot!) but i have a huge problem. my curls on the upper part of my head are becoming waves. My hair is very light n weight and its not super long, so i wasnt prepared for my curls to start stretching. The waves dont hold as well as the curls do n tend to look duller than the curly parts. I want to grow my hair to at least arm pit length but im scared that i wont have any curls to spare at that point and i LOVE my curls. Is there anything i can do?
