These four amazing women (all under 35!) are making the world a lovelier place. To return the favor, we asked fashion expert and Glam4Good founder Mary Alice Stephenson, hairstylist Patrick Melville for Goldwell Professional, haircolorist Dina Hasanovic of the Mark Garrison Salon, and makeup artist Sarah Lucero of Stila Cosmetics to show these change-makers the pampering they deserve.

Nadya Okamoto, 19
Cofounder and executive director, Period. The Menstrual Movement

Her Mission
Along Okamoto's right rib is a tattoo that reads RESILIENCE, a word that reminds her to push through hard times. Okamoto grew up with domestic abuse and unstable housing; when her family was forced to move out of their home, she had a two-hour commute to school on public transportation. That's where she met women who couldn't afford tampons or pads and resorted to using toilet paper, grocery bags, and cardboard. In 2014, Okamoto started Period. The Menstrual Movement, a network of young activists who distribute care packages of menstrual supplies to women in need. Today the 2016 L'Oréal Paris Women of Worth honoree and Harvard sophomore is running for Cambridge City Council— and continues to work to ensure women don't have to choose between meals and period products. She says, "Fighting for that keeps me going."

Her New Look
The Clothes
Okamoto describes her style as "sexy business-formal." Though she favors structured pieces, she really loved her voluminous tulle dress from Luisa Beccaria: "I am basically wearing a tutu, which is cool because I used to be a ballet dancer."

The Hair and Makeup
Okamoto's attitude: Go big or go home. Melville shaped her long layers and snipped her ends, then put an edgy spin on the classic topknot by adding tons of texture. He spritzed her damp roots with volumizing spray, blow-dried, teased strands, and twisted them up. For extra-special makeup, Lucero applied a bright raspberry liquid lipstick and glittery gold eyeshadow.

Her Reaction
"It's cool to feel so different—I have never had bangs before. And it means a lot to wear this shirt."

Maria Vertkin, 31
Founder and executive Director, Found In Translation

Her Mission
Vertkin, who moved from Russia to Israel and then to the U.S. in 1997, is acutely aware of the way a language barrier can diminish self-worth. "When you come to a place where your degree and skills don't count, you lose yourself," she says. In 2011, she started Found in Translation, which trains bilingual immigrant women to become medical interpreters. "They help patients who otherwise wouldn't be able to access healthcare, and that's huge," Vertkin says. "It can be lifesaving."

Her New Look
The Clothes
While fashion isn't usually Vertkin's thing, she correctly predicted "I am going to look great in this dress." The Rubin Singer design clung perfectly to every curve.

The Hair and Makeup
Hasanovic gave Vertkin's auburn strands vibrancy with a tinted glaze. Melville then evened the length and curled her hair with an iron. Lucero used monochromatic makeup: lipstick, blush, and eyeshadow, all in dusty rose.

Her Reaction
"I have mixed feelings about the expectation that women should be beautiful, but I'll admit I look pretty amazing! I hope my crush sees this photo."

Rachel Doyle, 34
Founder, GlamourGals

Her Mission
At 17, inspired by her hairstylist grandmother, Doyle started GlamourGals: young volunteers providing makeovers and companionship for women in senior facilities. (In the photo, right, Doyle shares the spotlight with poet Rosalie Calabrese, 79, a former makeover client.) Doyle has had many memorably moving encounters. One woman, Faye, seemed indifferent to her special treatment, but afterward, Doyle got a call. "The activities director said, ‘I want to let you know that Faye was severely depressed and had stopped eating, but after your makeover she started eating again,'" Doyle says. "No medicine can do that."

Her New Look
The Clothes
Doyle says her everyday style is "all about the cool details"—and so is this Bibhu Mohapatra gown with fresh floral embellishments.

The Hair and Makeup
Hasanovic painted on buttery face-framing highlights. For Gisele Bündchen–esque waves, Melville added extensions, an item on Doyle's beauty bucket list, and used a curling iron. Lucero kept her makeup polished with glowy blush and bronzer, soft brown shadows, and a pink lip glaze.

Her Reaction
"I've seen thousands of people enjoy the makeover experience, so I can really appreciate the glamour treatment. I feel like a princess."

Nicole Russell, 31
CoFounder and executive Director, Precious Dreams

Her Mission
In 2010, Russell's then-4-year-old foster sister, Miracle, was suffering from nightmares. After seeing what a difference stuffed animals, pajamas, and books made for Miracle, Russell was inspired to help other foster and homeless children self-soothe and sleep better at night. Her organization, Precious Dreams, not only provides these bedtime items but also brings activities and guest speakers to shelters and group homes. With chapters in New York, Los Angeles, and Baltimore, her cause now goes far beyond teddy bears. Russell says, "When these kids lie down at night and see happy things, it could possibly help them dream better."

Her New Look
The Clothes
Russell's wake-up-and-take-notice Oscar de la Renta number is the opposite of her typical ensemble. "Most days I'm surrounded by children, so I like to dress as comfortably as possible," she says. "But it was so nice to go glam for a day."

The Hair and Makeup
Hasanovic lightened Russell's nearly jet-black hair by painting on caramel highlights that enhanced the warmth of her complexion. Melville trimmed her ends and used a wide-barrel curling iron to add voluminous loose waves. Inspired by Russell's pewter manicure, Lucero did a striking smoky eye in navy and cobalt and applied a sheer copper lip gloss to add contrast.

Her Reaction
"I've built a career on making myself feel good on the inside, but it's empowering to see that reflected in my appearance. This dress is the perfect representation of how I feel: bright and beautiful."

Fashion With Heart
This marks the fifth year that fashion expert Mary Alice Stephenson has worked with O to give the red-carpet treatment to outstanding women. As a 15-year veteran in the style industry, Stephenson knows the uplifting effects a little "me" time can have: "It is often hard for givers to receive, so I love fussing over these women, making them feel special, and empowering their organizations." In fact, this work is her mission: Stephenson's organization, Glam4Good, provides meaningful makeovers, clothing giveaways, and confidence-boosting fashion and beauty initiatives for everyday heroes and people in need. "Mary Alice is an invaluable resource," says O creative director Adam Glassman. "Beyond her talent, it's her passion—and she does it all with a smile."
