When Caila Quinn first appeared on The Bachelor for Ben Higgin's season, everyone and their mother thought the same thing, "This girl should win based on her hair alone." Her long brown curls perpetually looked perfect. Even during deep-sea fishing and on farm dates, not a shiny strand was out of place. And when she returned to our TV screens for Bachelor in Paradise, you guessed it, her hair still looked damn good when she was outside all day in the humidity. Lucky for all of us, Caila Quinn spilled her hair secrets to Allure. We recently chatted with the 25-year-old to find out which products she can't (and can) live without, what curling iron she uses, and what tips she picked up from Jojo Fletcher and Becca Tilley.

The key to flawless hair is her blow-drying technique.

Before Quinn curls her hair, she blow dries it using a technique she calls "bookends." First, she starts with her bangs and the crown of her head to add volume. Then, she blow dries her ends. After that, she does the middle. Why? "This keeps the middle smooth, but also gives the top and the bottom some bounce," Quinn tells Allure. Then, she takes her time curling her hair, starting with the bottom layer working her way to the top.

Her hair routine hasn't changed since high school.

Yup, she's a woman of consistency. Before Quinn appeared on national television in hopes of winning the heart of Ben H., she used the same curling iron, shampoo, and conditioner she's using right now. "I've used the same one-and-a-quarter-inch barrel from Conair for almost 10 years," Quinn says. That's right, her now-famous curls have been a decade in the making, and she taught herself how to do them all on her own. "I would always just practice and curl," she says. "I never watched tutorials, but I knew what worked well for me."

Her love of Biolage shampoo and conditioner hasn't changed either. "The same one I use now is the same one I used on The Bachelor and in high school," she admits. "I have always loved the scent and the luxury feel of them." And in case you were wondering, she only uses the conditioner on her ends twice a week.

Of course, she has a ride-or-die hair product.

She's been using her all-time favorite, moisture product since high school, too. "Once a week, I deep-condition all of my hair—except the roots—with

," Quinn says. Not only is it inexpensive, it's also keeps her hair on point. "Whether it's a date in Jamaica or on the beaches of Paradise or traveling in Switzerland, it keeps my ends smooth and my hair healthy," she says.
