For some reason the Thieves Guild Hood is glitched and makes my character bald when he's a vampire.

I'd kinda think something like this would've been fixed by now but I guess not.

Does the Thieves Guildmaster Hood glitch also or does it work properly?

You can become Guildmaster of the Thieves Guild? I finished the main questline and I always thought it was Brynjolf because he always says he's busy with getting the Guild back on its feet when you try to talk to him.

You gotta do the side quests for the guild 5 for each major hold minus riften. After you done this you finally become guild master since you are the one who got the guild back on its feet.

The unofficial Skyrim patch fixes this. if you don't want those there is "Vampires hood Fix" by KitiFolien on Nexus that addresses that specific problem that fixed it for me before the Unofficial patch fixed it.

Keep doing the jobs for each major city (whiterun, markarth, solitude, windhelm), and eventually you will be offered special jobs for each one. once you do these special jobs, you can consider these holds under TG control. it's amazing, you can see that tonilia and the other fences have more money and there are extra merchants on the ragged flagon.

I LOVE this aspect of the thieves guild, I usually do these jobs even before starting the goldenglow state mission.
