Maui Moisture Shampoo- Hair Loss?

Recently I’ve been losing a crazy amount of hair. I’m actually shedding. Hair falls out after I run my hair through it, and it’s crazy in the shower. I’ve never experienced hair loss this bad. I know there’s a lot of factors that could cause this, but I’m not stressed, I’m eating well, I’m working out, and yeah. The only thing that I could think of was the Maui shampoo brand. I’ve bought it about 1-2 months ago and I loved it. I’ve been using it ever since, but now with this really bad hair loss I think I’ll stop. Has this ever happened to anyone due to shampoo? Especially this one? I could also use tips to prevent hair loss if anyone has any. Thank you so much!
