Mandy Moore for Garnier and Other Celebrity Beauty Campaigns of 2017

This Is Us star and former blonde Mandy Moore is the new face of Garnier. According to Mandy, this is a perfect fit, as she counts going brunette as a moment of "significance" in her life. "“I love to change my hair because, in a world where so much is out of my control, it makes me feel like I’m doing something to shake things up," the actress said in a press release.

Along with starring in Almay's new "Reveal the True You" campaign, Rashida wrote a set of comedic videos for the brand. Rashida hopes to bring some relatability to her role as an Almay Mega Influencer, saying in a release that, "There is so much pressure to portray an idyllic life, especially through social media, and honestly, does anyone really have the picture-perfect Matcha Latte every day? It was this thought that sparked the idea of showing
what my life as an influencer would really be like, behind the curtain, imperfectly perfect."

The Big Little Lies star is the newest YSL Beauty Global Makeup Ambassador. Her first project with the brand will be "Before the Light," where she will serve as makeup guru to up-and-coming musical artists. She will also work on the Tatouage Couture lipstick campaign, which launches August 2017.

"YSL Beauty has always been one of my favorite brands. Their ability to combine the chicest of styles with a raw edge has always been to me one of the best ways to express yourself through fashion and beauty. Nothing is forced, nothing is fake, but everything is bold, strong, and unafraid. I'm very excited to work with this legendary and timeless company," Zoë said in a press release.

The stunning actress starts her ambassadress position at the Cannes Film Festival, where the brand will be celebrating its 20th anniversary as an official beauty partner. She'll also be the face of a brand-new mascara formula, Voluminous Lash Paradise Mascara ($10), which is designed to give the wearer a lush, fluttery fringe.

According to the Nioxin team, this partnership was a perfect, organic fit. Naya became the brand's celebrity ambassador because she experienced hair loss after the birth of her son, Josey.

"I'm excited to really help people – whether there's a new mom out there who doesn't understand why her hair has changed or started to thin, or a woman who is constantly dealing with dry scalp (like I was) – there is a solution," Naya said in a press release.

Game of Thrones star Emilia Clarke will lend her mug to Dolce & Gabbana as the face of its The One fragrance, debuting in September 2017.

Designers Domenico Dolce and Stefano Gabbana released this statement: "Emilia Clarke embodies perfectly the Dolce & Gabbana woman: she is radiant and lively. Her personality and natural beauty will capture the essence of this new campaign: joyful, spontaneous, and full of life. She is The One!"

Bella Thorne is lending her lush lips to Buxom, which is known for its pout-plumping glosses. In her role as "babe" for the brand, Bella will star in digital campaigns and social media content.

Maria, who famously was the first model to walk the Victoria's Secret Fashion Show runway with natural hair, was named the newest face of L'Oréal. She joins celebrities like Jennifer Lopez, Liya Kebede, and Blake Lively and will star in international ad campaigns and represent the brand at press events.

The talented songwriter, producer, and singer joins the brand as part of its "Hair Talks — Make Your Statement" campaign, which will focus on building a community of empowered women who are encouraged to show off their unique hairstyles. In addition to kicking off the campaign with a concert, Tinashe will be creating content around her own hair's story for the John Frieda website and social media channels.

Gigi is just one of the major influencers to join Revlon's new team of influencer ambassadors, who are not exclusive to the brand. She, along with Kandee Johnson, Sabrina Carpenter, and Etienne Ortega will be bringing conversations about Revlon to their own unique audiences.

“We see a big opportunity to be part of the conversations that are happening naturally and organically in the social sphere,” Tracy Rohrbaugh, vice president of marketing for Revlon, told WWD. “The beauty consumer is multifaceted, but it doesn’t stop there — she’s participating in conversations about lifestyle, fashion, and celebrity. We were thinking about how we could tap into those conversations with our brand.”

The YouTube personality is the new face of the brand's iconic Original mineral foundation. In addition to helping create shade extensions of the classic formula, she put together a curated gift set ($50) for the company.
