With uniformly long hair and no short layers I suffer from even more "root droop" than I already have. Though it's really curly, I don't like the way the hair just flops in my eyes/face when it's longer. I want as much root lift as possible, which for me means less length around the crown area.
Also, when it's all one length (shoulder length or longer), it weighs itself down and it's less curly. I prefer it curlier.
