Headlining

My car’s headlining is squeaking in the back. The board, or whatever it’s wrapped around is loose. If I put my hand on it while driving, it stops squeaking.

So here’s my question. How do I fix it without making it look tacky?

Original Shoo goo is my friend, and it is clear, you should secure it with a board or something holding it in place for at least 24 hours, longer if cold, 3 days if you can live with it. and make sure you glue at points that will secure it in place. If you have any questions, doubts or need more explanation please ask!

My only question is will I have to completely remove the headlining to use it? Cause right now the headlining is on and secure, just loose and squeaking.
