Why does this script appear to be working in Studio but not Roblox Player?

local Gate = game.Workspace.OwOMachine3000.Tunnel.Section3["3rdScanner"].LaserGate
local players = game:GetService("Players")

Gate.Touched:Connect(function(hit)
	if hit and hit.Parent:FindFirstChild("Humanoid") then
		local Char = hit.parent --this contains all the character limbs
		local Name = Char.Name
		local head = Char.Head
		local hair = Char["Brown Hair"]

		local plr = players[Name]
		print("plr")

		wait(5)

		for i,v in pairs(Char:GetChildren()) do
			if v:IsA("MeshPart") then
				
				v.Color = Color3.new(1, 1, 1)
				head.Color = Color3.new(1, 1, 1)
				hair.Parent = game.ServerStorage
				
			end
		end
	end	
end)

This is a script I've got that is supposed to change the colour of all the body parts and remove the hair when the Client touches a brick, it works perfectly in Studio and in a Local Server but when I play the game on Roblox it only changes the head colour and nothing else, and the hair stays on the character, does anyone know why this is?

1. You can get player with players:GetPlayerFromCharacter(Char)
2. Not every player has brown hair unless you give it to them first(I assume you do)
3. Change to:

for i,v in pairs(Char:GetChildren()) do
            if v:IsA("Part") then
                v.Color = Color3.new(1, 1, 1)
                hair.Parent = game.ServerStorage
            end
        end

1. I don't remember if Color3 works on parts but if it doesn't then use BrickColor.new
