Help! Detect if NPC is wearing a Hair if yes, remove it!?

Hello, i need to do this code work:

if game.Workspace.NPC.Hair then
game.Workspace.NPC.Hair:Destroy()

The script need to detect if the NPC is using a Hair and if yes, delete it and if not... execute this:

if game.Players.LocalPlayer.Data.Hair.Value == 1 then
hair = game.ReplicatedStorage.Hair1:Clone()
hair.Name = "Hair"
hair.Parent = NPC

Full code:

local Sound = script.Parent.ClickSound
local Menu = script.Parent.Parent.Parent.HairChooser
local MenuAppearance = script.Parent.Parent.Parent.MenuAppearance
local NPC = game.Workspace.NPC
local cam = game.Workspace.CurrentCamera

function onButtonClicked()
if game.Workspace.NPC.Hair then
game.Workspace.NPC.Hair:Destroy()
end
Sound:Play()
wait(0.5)
game.Players.LocalPlayer.Data.Hair.Value = 1
wait(0.1)
if game.Players.LocalPlayer.Data.Hair.Value == 1 then
hair = game.ReplicatedStorage.Hair1:Clone()
hair.Name = "Hair"
hair.Parent = NPC
wait(0.1)
Menu.Visible = false
wait(0.1)
MenuAppearance.Visible = true
end end

script.Parent.MouseButton1Click:connect(onButtonClicked)

for i,v in pairs(game.Workspace.NPC:GetChildren()) do -- Iterates through the npc's children
	if v:IsA('Accessory') then -- if the child is an accessory (hat) then...
		v:Destroy() -- Destroy the hat
	end
end

However, I'm not sure how to make it destroy only hair. This would delete all of the NPC's accessories.
