this mod contains small .esp file containing additional race edits for Garrett Thief Armor's Hoods that originally are not compatible with vampire races (the character goes bald)

it's a simple edit explained by ToggleAI
I'm merely implementing what he explained here
just saving you few minutes of editing :)
