I wear buns and French twists 90% of the time now. When I reach my goal I'll probably still wear them, but only 70% of the time.
I started "protective stying before I even knew what it was called. I just had to keep my hair out of my first baby's little hands. Then I went on and had three more babies and each one liked to grab my nose, my hair, my earrings, ect... So I stopped wearing earring's other than studs, and I kept my hair up. Now it's just a habit, I'm so used to wearing my hair up that it actually feels kind of strange when I wear it down and I feel it tickling my back.
For me, the purpose of growling long hair is simply personal pleasure. I do love to take my hair down at night after the kids have all gone to bed and play with it and admire it...
Then I put it back up.
Long hair makes me feel very feminine and beautiful, even if I do wear it up usually. It's like wearing pretty lingerie all the time, even under a grungy old sweater and jeans; nobody else knows it's there, but it gives the wearer a little extra "boost"
