Monosodium Glutamate is in damn near all processed salty food: from Doritos to ranch dressing.
Why does that matter? Well, MSG in small doses is fine; the problem is its in damn near everything. What happens when you eat too much? Headaches and balding. Yes, MSG straight up causes balding. Stop eating processed bullshit.
Tl;Dr: MSG causes people to go bald and its in almost all junk and processed food.
