Natural hair // Hair Types

LO
So I've just started the natural Journey a few months back (except past month I broke and straightened the fuck out of my hair and now I have a few split ends), my hairs a little past my shoulders straight and just right above my shoulders curly. It's at a length now where I'm comfortable wearing it down and don't feel like I look like a man. I was just wondering if y'all could help me determine my hair texture on the a-c scale. 
I'm biracial and only really am in contact with my moms side (white) so I have no one to talk to and ask about this stuff hence why my hair was so damaged as a child from my mom perming and straightening it so much.
 
These are the only pictures I have right now and don't mind the faces I pulled them from conversations on snapchat 😭. You can kind of see my curl pattern at the side from my pony tail. I'm pretty sure I have 3 different types but at least I'll know where to start. Also does anyone know any products to keep the curls defined after a few days without washing? They stay normal for like 2 days if I don't brush it but as soon as a brush goes through it looks like a hot mess. Thanks cheers.
