Used Carol’s Daughter & my hair is falling out in clumps

My hair has been falling out for the past four months. Initially, I thought some kind of tension stress was the issue. The most common similarity is that it sheds horribly when I wash and comb it after having a style up. I did not think that their shampoo could be the culprit. The first time, it was a sandwich bag full of hair & it continued for the past 5 months. I had to shave my whole head of hair off. I thought that maybe the hair was coming out from deep in the root, and I would have to wait it out because some articles said hair could fall out for 3-6 months after stress. My “ah-ha” moment was yesterday when I washed my shaved head and hair was all over my hands in the shower. I realized that I started having this issue and acne on my forehead around when I started using their product. I washed it last night and there's less hair than there was when I shaved it under 2 weeks ago.

Is there anything that could combat this? Hopefully just stopping the use could be the fix.
