are you really trying to change the appearance of 1 person or all cuz if its all then you should look at this https://devforum.roblox.com/t/replacing-the-default-character-with-a-custom-character/19344 if not though then it probably hasnt loaded in yet and was getting called
use WaitForChild("OroHair")
