Makeup artists normally tweeze actors and actresses’ eyebrows every 3 to 4 days to maintain a well-groomed look, says Lljubo-O’Brien. But of course there are always stray hairs in between. To tame them, she uses a brow gel to slick hairs into place (try E.L.F. Wet Gloss Lash & Brow Clear Mascara, $1.50). Then she brushes the hair upward toward the arch, and then straight back and to the side to lengthen the brows. For touchups on the go, Lljubo-O’Brien uses a wax pencil like NYX Eyebrow Shaper, $8.75. It’s easier to apply, since you don’t have to worry about dropping your wand or spilling any gel, she says.

When it comes to trimming ear and nose hair … that’s a different story. “I always feel bad when I have to do this, because it’s uncomfortable to admit hair is growing there,” says Anderson. Because no one really wants to do it, sometimes “you hand it off to [an assistant],” says Berquist-Barker. Looks like those poor junior stylists get all the glamorous work.
