The Lineup is a monthly series where we’re giving you an inside peek at the beauty lineups of cool fashion people, editors, makeup artists, hairstylists, and estheticians—all the people we trust the most. Get ready for a behind-the-scenes look at all the can’t-live-without products that make their worlds go ’round.

I think we can all agree that glam squads deserve more credit. Hairstylists, makeup artists, and nail techs work behind the scenes to create stunning looks and help stars look their best on the red carpet. One of the most talented in the biz is Mara Roszak, a celebrity hairstylist, the co-owner of Mare Salon, and the founder of the cult-favorite clean-haircare brand, Rōz Hair. She’s basically a hair whisperer for A-list clients including Hailey Bieber, Cara Delevingne, Olivia Wilde, and Zoe Saldana. ​​”I have such a unique view into what people are looking for when it comes to their hair,” she tells me. “I hear the daily struggles that people are having, and I’ve always been able to help. It’s a true gift to be able to provide these solutions that come naturally to me.”

According to Roszak, the products in your routine are vital to your hair health. “After living and breathing products for 20 years, good ones really do make such a difference,” she says. By 2021, she had a kit full of go-tos that gave her clients gorgeous, bouncy hair. But there was a need for clean haircare made with natural, sustainably sourced ingredients instead of chemicals you can’t pronounce, so she developed a capsule of nine luxurious and effective formulas that deliver red carpet–ready results.

If she had to pick a favorite from her line, it would be the Rōz Foundation Shampoo ($39) and the Rōz Foundation Conditioner ($42). “My hair has never been happier with this duo! I just never want to use any other shampoo or conditioner,” she says with a smile. Keep reading to see the rest of the go-to products she uses as a founder, busy mom, and world-traveling hairstylist.

“The Sheila Stotts brush has been my favorite detangling brush for several years. I particularly like how the bristles don’t all have the little ball on the end, which can lead to snapping or breakage.”

“This is my new daily essential and my latest debut from my brand. I mix this in with my styling oil to smooth, hydrate, and protect my hair. It adds such beautiful definition and is de-frizzing, so it’s the perfect air dry in a bottle. I also will use this on dry hair, and it’s never too heavy and never weighs my hair down. Think of it as the perfect day-two refresher for smoothing and hydrating.”

“I use this to remove my mascara. Jo Baker, who is an incredible makeup artist and a good friend, founded this line and recommended it to me, and I’ll listen to anything she says! It removes my mascara easily and seamlessly but is super gentle. My face never feels irritated after using it.”

“This product really nourishes my lips in the summer and winter. Unlike most lip balms, I feel like this product really hydrates and lasts. I’ll put this on at night or first thing in the morning while I’m getting ready.”

“I was on the hunt for a new mascara, and I heard such great things about this one. It gives an incredibly quick and easy lift. I’m often doing my makeup in the car very quickly, so this mascara is a lifesaver for me. It boosts my lashes and lasts all day.”

“This is really the only styling product I use on my hair daily. It adds shine, removes frizz, and is super lightweight, so you can layer it on both dry and damp hair. I’ll put this on my mid-lengths to ends daily to enhance my texture.”

“I love this as my daily foundation. I really want to see my skin and don’t want it to look like I’m wearing makeup, so this has been my go-to for a very long time, and my skin looks so dewy every time I use it.”

“Neen is a really cool new brand that I’ve been loving! This specific product felt so nostalgic to me. I love the glimmer that it gives, and I use it as highlighter on my cheekbones. I like how it doesn’t feel sparkly but glistens and gives me that natural glow.”

“This shampoo and conditioner is so essential to have in your shower! It nourishes and hydrates, and my hair has never been happier. The shampoo and conditioner are completely clean, yet they lather and cleanse so well. This duo is perfect, and it doesn’t strip my hair. I’m very sensitive to my hair looking dirty, so it’s important for me to have a shampoo that cleanses and a conditioner that hydrates my curly hair.” Shop the matching Foundation Conditioner ($42).

“I’ve used this perfume for so long. It’s a beautiful, earthy fragrance that wears beautifully. I will never get sick of it!”

“I love this serum. I’ve been using it for years and years. It’s totally luxury in a bottle. It smells incredible, and my skin feels genuinely hydrated. I absolutely love when my skin has a glow, and this product does that for me perfectly!”

“A good friend of mine, Kara Yoshimoto (who also happens to be a very talented makeup artist), gave me this lip and cheek balm. I really love products that are multipurpose, so I just throw this in my purse and can use it anytime. It just gives that perfectly flushed, juicy look, which I’m obsessed with.”

“This is my absolute summer essential. The kukui oil is a natural UV protectant, which saves my hair when I’m out in the sun all day. It’s all organic oils that protect, hydrate, and nourish the hair. I’ll lather my hair in this oil before I swim, go to the beach, or do a workout. It’s also really nourishing for your skin.”

“I love Shani—she’s an incredible facialist. I trust anything she does, so when I was looking for a new daily cleanser that wasn’t going to dry out my skin but would remove my makeup all in one swoop, I started using this cleanser, and I’ve been obsessed ever since.”

“I just started taking the hair pill. A good friend of mine, Leanne Citrone, created the brand, and I’m really looking forward to seeing how my hair strengthens over time using these supplements.” Shop the Mood Pill ($48).

“I love this concealer and how it’s a clean formulation. It’s quite moisturizing even if it’s on the thicker side. It can be very easily blended into the skin but really does work to cover any dark spots or redness on my nose. It’s great for dark circles under the eyes. I sometimes blend it out with a lightweight cream to make it a touch more sheer.”

“This is kind of a lighter, citrusy fragrance. I switch off between the Chanel Sycomore and this one. This is definitely a great summer go-to. It has a grapefruit note, and yet it’s totally not overpowering.”
