Whose hair is this on my head?!?!

I used to have soft curls that I could grow long and run my hands through. I turned 39, got hit with the peri stick, and now look like your hippie aunt who tie dyes her own mumus. I don't recognize the hair growing out of my head anymore, but if it's yours, please come get her.

The grays and dullness I can forgive, but what the hell happened to my texture? I look like I've arrived in town to herald pestilence. And the knots... my god the knots. I scoop coconut oil by the handfuls directly onto my hair just to run a brush through it. I love my long hair, but I don't think I can emotionally afford to keep this for long. Is there some magic product or process that can salvage this, or should I order the mumu?
