It also depends on how loose or tight your curl pattern is. If you have a looser curl pattern, you will need a certain amount of length before you will see the complete curl. This is why wavies and even some 3a curlies appear to have straight roots. If you cut hair with a looser curl pattern too short, it may actually appear straight; the curls will show up more when it grows out some, and then as it gets past a certain point, the weight of the hair may start to pull out the curl again. You may also have different types of curl patterns on one head of hair, so different sections may have more or less curl at different lengths. I have combination 2c/3a hair - I cut my hair very short once (longer than a pixie, but shorter than a traditional bob) and the sections with looser curl looked almost straight, with very little wave, while the curlier sections formed tight little ringlets. Now my hair is about BSL and the sections that were almost straight now have enough length to curl more and appear curlier, while the curlier section has more weight and is less ringlet-y. My guess is that if you keep your length at or below the shoulders, you will still have enough length to see your complete curl pattern, and may even see your hair curl up a little more. As far as bangs, it just depends on how curly that section of your hair is. You may be able to do bangs, but you may have to cut them a little longer to work with your wave/curl pattern (or decide if you want to straighten them).

My favorite brands are Kinky Curly, As I am, Curly Kinks, Curl Junkie, and Darcy's Botanicals. Also love sealing with oils (loving argan oil right now) and styling with jelly products (KCCC is my current favorite). Mostly trying to keep it simple!
