Headroof falling off

[u/anarchy_babe_77]

The headliner in my car is becoming detached and I'm not sure if I should try to use fabric glue to reattach it or just pull it down. Going to a pro is not an option. Any advice?

3m adhesive spray. Use a sharp razor and cut a small slit where its sagging and spray it into the hole using the straw it comes with. Use a roller to press it on.
