Judging from her roots, I'd guess 3b. Her hair looks manipulated though. Most of her hair looks like it was braided while wet and then taken out when dry. It has that crimped but not frizzy look that braids give. Anyway, I like that she has a lot of hair, but has found a style that flatters both her hair and face. And her hair looks healthy.
