Would box braids be a good choice for my 2b/3a transitioning hair?

My hair is 2b/3a, but is still transitioning and has a good amount of damage (split ends, but mostly crinkly, wiry hairs that feel kinda nasty). My roots are pretty straight compared to the rest of my hair, but I rarely have good curly hair days because my hair looks so stiff, tangled, frizzy, and the curls are really undefined, which makes my hair look not full (thin?). Would the box braids damage my hairline and baby hairs? Would they improve my gross hair?  Are box braids in the picture even possible for me to have because of my hair type?
