Can I perform Wudhu right after my Ghusl? And is it permissible to do Wudhu even if my hair is wet from the Ghusl, or do I need to dry it first?
Bismihi ta'ala
Yes, you can perform wudhu' right after your ghusl, but for wudhu' it is a necessary condition that your head and your feet be dry when you want to wipe them.
Once you finish your ghusl, dry yourself down, and then do wudhu'. Another option is do your wudhu' before you do the ghusl.
And Allah knows best.
