Sans for Lucy Hale and Cara Delevingne, Vanessa Hudgens has some of the best brows in the biz — girlfriend was blessed with lush, thick face framers. And while you might think it takes some serious brow definer or tweezing sessions to keep those puppies in check, the Grease Live! star says her go-to routine is actually far more simple.

In fact, the 28-year-old is in the habit of using an everyday item that we guarantee most of you already have stocked at home (we hope): It’s soap. Yes, soap gives her those A+ brows.

It’s a trick the actress learned from her makeup artist. Hudgens says that her MUA simply rubs an eyebrow brush into a bar of soap then into her brows to get that added volume. Also, you’re not likely to run out anytime soon. “You have soap!” she says. Double duty beauty? Yes, please!

As for the brush, Hudgens favors eco-friendly options like Eco-Tools (she’s a brand ambassador for the company) — specifically their Lash & Brow Duo Brush( $3). “They use bamboo, recycled aluminum, cruelty-free bristles for their brushes,” she said. (Just in time for Earth Day too!)

Perfect brows for $3 and a bar of soap? Sold!
