Guess what? Using Gorilla Glue on your hair is apparently a “bad, bad, bad idea.”

TikTok user Im_D_Ollady—real name Tessica Brown—issued the warning in a couple of now-viral videos in which she claimed to have used the heavy-strength adhesive to “finish off” her hairdo. Brown explained she had run out of her go-to hair spray one day and decided to use the Gorilla Glue spray as a substitute. Weeks and more than a dozen washes later, Brown’s hair has remained unmoved.
