Removing the face and hat simultaneously doesn't work ... ?

So you told me that you wanted to remove the face along with hats. If this is true, your going about htis wrong

local lplayer = game.Players.LocalPlayer
local Head = lplayer.Character.Head

for k,s in pairs(lplayer.Character:GetChildren())do
    if s:IsA("Hat") then
        s:Destroy()
    end
end

This allows you to remove hats. To remove the face on roblox characters, you have to make another loop to make it work effectively

for i,v in pairs(lplayer.Character.Head:GetChildren()) do
    if v:IsA("Decal") then
          v:Destroy()
    end
end

This will loop through the player's head and delete anything that Is a decal
