Why we love it:

This best-selling duo is your cleanse day essential. 

The Foundation Shampoo lathers beautifully, using clean, coconut-based surfactants to gently remove build-up, creating a perfect foundation for styling. The Foundation Conditioner, rich with peptides and ceramides, is deeply hydrating and smoothing. Suitable for all hair types and textures. Sulfate-free & silicone-free. 

Is sulfate-free shampoo right for your hair? Sulfates are effective cleansers, but the right choice depends on your hair, scalp, and wash routine. Learn how sulfates work in shampoo and who may prefer sulfate-free in The RŌZ Guide.

Includes Foundation Shampoo, 300 mL and Foundation Conditioner, 300 mL. Need larger bottles? The 900 mL Foundation Duo includes both formulas in salon sizes.

Push down and twist counterclockwise to unlock your pumps for the first time.

Thoroughly soak hair and massage Foundation Shampoo into scalp, adding more water where you need extra lather. Rinse out and repeat for a salon-grade cleanse.

Follow with our Foundation Conditioner, combing through ends, and letting it nourish your hair for a few minutes before rinsing it out.

Our signature fragrance evokes the spirit of an untamed California garden, verdant and clean, with subtle notes of woody vetiver and fresh, rejuvenating citron.

Notes of bergamot, fig & neroli blossom

Stylist Secret

“Spend extra time on the back of the head where most build up occurs. Splash a touch more water into the scalp to work up an incredible lather. Shampoo a second time for a salon grade feel. Keep a brush or comb in the shower. Detangle hair while conditioning to ensure even distribution and silky smooth strands.”

Mara Roszak

RŌZ Founder and Celebrity Stylist

FAQ

We always say to listen to your hair here—there’s no one-size-fits-all. Most people find their sweet spot is 2-3 times per week, but if your scalp leans oilier, you can absolutely use it more often. It’s a gentle, sulfate-free formula, so it cleans without stripping, which makes it great for regular use.

Yes! The Foundation Shampoo is safe for both color-treated and keratin-treated hair. It’s sulfate-free and designed to cleanse gently while helping maintain the integrity of your color and treatments.

In case it gives you a little trouble, here's a trick! Please first tighten the pump around the neck of the bottle—as if you are simply tightening the pump, as if it’s too loose. Then, push down on the top of the pump and twist counterclockwise to pop up.

Start small—you can always add more. For most hair types, a nickel to quarter-sized amount is a good starting point. Apply only to your mid-lengths to ends, and avoid the roots.

Yes! Our formulas are designed to be lightweight and nourishing without weighing your hair down. If you have fine hair, start with a small amount and keep it focused on the ends to maintain volume and movement.

Fresh, airy, and green.

Sparkling bergamot, blood orange, mandarin, and pink pepper open with an uplifting brightness, unfolding into lush fig leaves, luminous neroli, and delicate jasmine. Grounded by earthy vetiver, warm amber woods, and soft musk, the scent captures the abundance of California—verdant landscapes, crisp morning air, and a sense of restoration. Bright yet grounding, it leaves behind a feeling of calm and a gentle return to nature.

My daughter's hair has never

Love these products and THE SCENT!!

"The scent of Rōz is absolutely delightful and leaves my hair soft, smelling wonderful and full of volume. I appreciate how lightweight it is, and how I can control it by adding some clarifying washes and/or deep conditioning in addition to the standard shampoo/conditioner. I can't get enough of Rōz and so far, have nearly everything in the collection! So good!"

— Jennifer L. (5/5)

Love the Scent & How My Hair Feels

"★★★★★ This has easily been one of my favorite shampoo and conditioner duos I’ve used in a while! My hair actually feels clean after using the shampoo, and the conditioner leaves my ends feeling soft and moisturized without weighing my hair down. The scent is also really nice—fresh and clean without being too strong. Definitely a duo I’ve been enjoying!"

— Abigail M. (5/5)

just wow for this 2A soft curl girl

"When I took a pump I was worried the scent would be too strong and that the shampoo would be too harsh but its perfect. It gets rid of build up and gives me a perfect reset without stripping moisture or giving me an itchy scalp. I have fragrance allergies but it didn't make me break out. I'm so glad I found this shampoo for my very fussy hair/skin!"

— Melissa W. (5/5)

Q&A

Does your fragrance contain phthalates?
Hi Maggie, Thanks for your question! Our fragrance is free from PEGs, nitromusks, and phthalates. We use a thoughtful combination of natural and safe synthetic fragrance ingredients that are IFRA-compliant and used at less than 1% total concentration. By combining natural and synthetic components, we achieve a scent that is both elevated and consistent—safe for scalp and hair, tested for allergen thresholds, and transparent by design. Xx, Team RŌZ
Could you describe the scent of both the shampoo and conditioner?
Hi Mary! Thanks for your question! Our signature scent contains gentle notes of bergamot, vetiver, neroli, and fig – inspired by the misty mountains and wildflowers of Big Sur, CA. Xx, Team RŌZ
Is this shampoo sulfate free?
Hi Dawn! Thanks for your question! All of our products are vegan, cruelty-free, sulfate-free, paraben-free, triclosan-free, and gluten-free! They are color and extension safe as well. Feel free to reach out to us at hello@rozhair.com with any other questions! Xx, Team RŌZ
Is the walnut oil refined?
Hi Tania! Thank you for your question! Our shampoo and conditioner contain hydrolyzed walnut rather than highly refined oil. While the oil is processed (hydrolyzed) to improve its cosmetic performance, it may still contain some residual proteins that could potentially trigger a reaction, depending on the severity of the allergy. Because of this, we always recommend discussing with your doctor or performing a patch test before using any product containing walnut derivatives if you have a known walnut allergy. Your safety is the most important thing. Feel free to reach out to us at hello@rozhair.com if you have any other questions about our product ingredients, or if you'd like to know which products in our line do not contain the hydrolyzed walnut oil. Xx, Team RŌZ
Can you use this shampoo on color treated hair
Hi Kelli! All of our products are completely safe to use on color-treated hair. The Foundation Shampoo & Conditioner formulas were designed to be gentle and shouldn't strip or compromise your color-treated hair as they are sulfate free and sodium chloride free. Xx, Team RŌZ
