How to remove a face in a customized character?

So i made a customized character which has such a script (Only head because thats the problem) :

--// Head 
  local ClonedH = Head:Clone() 
  ClonedH.Parent = char

  ClonedH.Main.CFrame = char:WaitForChild('Head').CFrame 

  local Weld = Instance.new('ManualWeld') 
  Weld.Part0 = ClonedH.Main  
  Weld.Part1 = char:WaitForChild('Head') 
  Weld.C0 = ClonedH.Main.CFrame:Inverse() * char:WaitForChild('Head').CFrame  
  Weld.Parent = char:WaitForChild('Head') 

, and i used this script to remove the face :

local Players = game:GetService("Players");




function removeFace (character)
        local head = character:WaitForChild("Head")
        if not head then return false end

        for num, obj in pairs(head:GetChildren()) do
        if obj:IsA("Decal") then
            obj:Destroy()
        end
        end
    end

    Players.PlayerAdded:Connect(function(player)
        player.CharacterAppearanceLoaded:Connect(function(character)
            removeFace(character);
        end)
    end)

but it doesnt remove actually the face when i start the game in studio :C, what is the error?. I dont get anything in output
