I would just like to ask if a food can cause hair loss. Because I have a project for school and my topic is about hair loss vs. aging. For example if i eat a mango it will caused hair loss? is there something like that? THANKS~!

Mango does not cause hair loss. In fact, I do not know of any specific foods that would cause hair loss. Perhaps if you have a severe allergy to a certain food, that could cause hair loss… but in general, normal foods do not cause hair loss.
Good luck with your school topic. If you want more information about hair loss, you can read my book — Hair Loss and Replacement for Dummies.
