A hairdresser has made a stunning admission that he uses Gorilla Glue on clients — but warns there is only one way to safely use it on hair.

Salon owner Eric Vaughn revealed in a now-viral TikTok video that he uses the industrial-strength adhesive to secure hair extensions.

“So I’ve been using Gorilla Glue on people’s hair for years, but this is the only way that you should ever use it — at the end of a sew-in,” he says as he demonstrates on a blond woman.

“I’ll take my threads and knot them together, take a tiny little dot of Gorilla Glue, blow dry and cut that and that knot is going nowhere,” Vaughn says.
