Why soccer players should not wear helmets?

Answer 1

Soccer players should not wear helmets because they are not an authorized part of a player's equipment under Law 4 of the IFAB's Laws of the Game, the rules the world plays by. This is because in soccer, actions which might cause head injury are disallowed, unlike in American (Gridiron) football, where players would be at a substantial and imminent risk without their helmet.
