Be very, very careful if you try this at home, folks!
Lupita Nyong'o took to Instagram on Thursday with a slightly recent throwback vid showcasing an, er, interesting mane improvisation: The actress sits still while a hairstylist Vernon Francois uses a clothing iron (yes, that same device you use to unwrinkle your button-downs, blouses, etc.) to spritz and, as far as we can tell, steam her hair.
"My #tbt is a Hair tip from the infinitely talented @vernonfrancois: when you go #glamping and you forgot your spray bottle, an iron can come in very handy," the actress wrote alongside the short video, along with a cautionary hashtag, "dontturniton." (Don't need to tell us twice...)
Obviously, the hot plate looming over Lupita's flawless face is a bit scary, but Francois seems to have it under control (we bet there's a lot of trust involved).
