My hair is falling out and idk why...

:-) • ♡ 23 • Pisces ♡
I know this is gross (and I do clean all my hair up after every shower) but my hair has been falling out A LOT for the past couple months. And I have no idea why...
I'm half black and half white, I have extremely curly spirals (3b/3c hair type)... 2 years I cut all of my hair off to let my natural hair grow back healthier.
But it's obviously not going to get very long if it's all falling out and breaking off... If my hair wasn't curly and poofy, I'm pretty sure I would have bald spot.
What should I do?.. I love my hair, I don't wanna lose it. 🙁
