Tessica Brown finally washed that Gorilla Glue right out of her hair — thanks to a surgeon — but the painful drama means her Valentine’s Day’s gonna be more low key than she hoped.

We got Tessica at LAX Friday after her month-long, rock-hard hairdo saga came to a happy ending, and she tells us it’s time to unwind this weekend in Louisiana with her sister … and a little sippin’ and paintin’.

Tessica says she and her sis are going to have a nice steak dinner too, while she enjoys the sweet relief. You’ll recall, moments after the procedure ended Wednesday night, she mentioned having big Valentine’s plans — but sounds like she’s decided to take time to recover instead.
