Can breakfast cereal cause hairloss?

This is interesting.  I always felt like cereal smelled like dog food but did not know the affect on the body.  As a young girl I remember a cousin of mine who ate nothing but cereal and milk, he was suicidal. He would climb to the roof of our house and threaten to jump and kill himself.  I suspected  35 years ago it was not good to live on only cereal and milk.  I consult many women with hair loss who

eat cereal for dinner because they are too tired to cook.
