[ROBLOX] Asset Package Loading?

Hello, I have a question.

In roblox there is one simple script to load a hat or a hair onto your character.

The code I use to load a hair on my character was

game:GetService("InsertService"):LoadAsset(141742051):GetChildren()[1].Parent = plr.Character

but my question is, how can you make it so it loads a package on your character?

Thanks!
