Hair loss pls help!!

Micaela

I’ve been having a TON of hair shedding the last 3 months… I had my thyroid, iron and hormonal levels checked. My doctor doesn’t know what could be causing my hair loss. Please help has anyone experienced this and know how to get my hair back to being thick?? I am not on any medications right now and im not pregnant. This picture shows how my hair I lose every other day in the shower. I lose more in between those times too. Please help it’s really hurting my mental health.
