losing my hair

so ive been losing my hair because i don't have enough protein in my diet. I'm trying to change that I've been eating more meat and drinking protein shakes, I have even been eating more healthy snacks. My parents always told me I didn't eat healthy enough but I didn't believe them till now. Now i'm eating healthy but i'm super nervous that I will lose a lot of hair. I think ta slowing down but its absolutely terrifying.
