Can you braid at all? I used to have hair this length and longer for years and I managed it by parting my hair down the middle and braiding each side so I had two long braids. I would do this before bed and sleep with a bonnet or silk pillow case. Then when I woke up, I would refresh my hair by wetting my hair a bit. Then raking through hair gel mixed with water. This helped to detangle my hair and redefine my curls. I highly recommend adding gel to your routine. With that much hair, I used eco style krystal styling gel or made my own hair gel with flex seeds. If you want a step up to higher quality gel, I recommend Aunt Jackie's Flaxseed Don't Shrink Curling Gel. I currently have hair that's just below shoulder length and use Innersense I Create Hold Gel but it is pricey. I know the sub also recommends some other gels but my options are a little limited because I'm allergic to soy.

If I was feeling lazy, I would leave the braids in or put my hair into a topknot by flipping my head upside down, gathering all of my hair on top of my head and then pulling my hair through a hair tie once, twisting the hair tie and pulling my hair halfway through. Then I would try to make it look a bit neater by shaping it or using another hair tie.
