Any way to make this work?

You wasn't SPECIFIC so it doesn't A) Make their heads permanently transparent B) Fires only when you use _G.NoHeadPlayers() in ANY script C) Doesn't work as soon as you join because the game objects are still loading D) Does it to ALL players

_G["NoHeadPlayers"] = function()
    for i, v in pairs(game.Players:GetPlayers()) do
        local head = v.Character:findFirstChild("Head")
        if head then
            head.Transparency = 1
        end
        wait()
    end
end

-- USE    _G.NoHeadPlayers() IN ANY SCRIPT TO CALL THE FUNCTION
