Notes of bergamot, fig & neroli blossom

Stylist Secret

"For the most thorough cleanse & richest lather... ...massage shampoo into completely wet hair & scalp. 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. Rinse thoroughly."

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.

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.

Reviews

My daughter's hair has never

"My daughter's hair has never felt softer! She has platinum blonde, super long hair, the struggle has been real, until her mom bought her the Roz Shampoo and Conditioner. She is obsessed, loves the lovely light scent and the bounce and softness that Roz gave her. Highly recommend!"

— Vincent H. (5/5)

Wonderful!

"I love this shampoo & conditioner. I've been using it for over a week now and am impressed. Usually a day after washing I start feeling like the roots get a bit oily but not with this shampoo. I feel like its kept my hair feeling cleaner longer and I really enjoy the subtle scent it leaves. Its hard to tell if this helps fight frizz since I also use the milk serum & mouse daily but whatever is fighting off the frizz, I'm here for it and adore it. These are worth every penny in my opinion."

— Mayra G. (5/5)

Absolutely loving it!

"My hair hasn’t looked this great in years! blow-dry and most think I’ve straightened it! It Calms my frizz and is So healthy and shiny! ROZ Smells so light and wonderful. I will splurge on the leave-in next!"

— Bobbie (5/5)

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)

Get it!

"I am the pickiest person when it comes to hair products. Super skeptical. Honestly, had it not been for Lily Collins, I would have kept scrolling. That was just great marketing. All kidding aside, It’s totally worth it. Great product 10/10."

— Liangy F. (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)

Happy customer!

"Very pleased with their products. I like the way my hair looks and feels after I use the shampoo and conditioner. I just ordered the air thickening spray and it does seem to add some volume to my hair."

— Dorothy D. (5/5)

Foundation shampoo

"Just purchased. My daughter is obsessed with the products and I recently started using the shampoo, conditioner and milk rinse. So far, so good! It leaves my hair with a nice texture and I am looking forward to seeing additional long term results as I continue to use the products."

— Mary O. (5/5)

Q&A

Would you say that your shampoo is safe/beneficially formulated for color protection for color treated hair? Or is that not a claim you make.
Hi Lady! Thank you for your question! Yes, all of our products were formulated to be safe on color and keratin treated hair. Our products do not contain sulfates or parabens, which are the primary ingredients of concern with color-treated hair. Xx, Team RŌZ
Hi! I was excited to find this cleaner brand and was wondering if clarity can be provided on the fragrance/parfum… is it essential oils or synthetic? Thanks!
Hi LJ! We're grateful for your interest in our products and fragrance. At RŌZ, we embrace a comprehensive approach to clean fragrances in our products. Recognizing that both natural and synthetic fragrances can meet our high clean standards, we carefully select each based on their environmental impact and safety profiles. We sometimes favor synthetics as they can be less resource-intensive and have excellent safety profiles compared to their natural counterparts. By committing to ingredients that are gentle on the body and the planet, our fragrances not only meet but exceed the highest standards of clean beauty, delivering both efficacy and peace of mind. - Fragrance is less than 1%: To minimize potential allergens and irritants - No Nitromusks: We do not use nitromusks, which are synthetic fragrance compounds that can accumulate in the environment and have potential health concerns. - IFRA Compliant: All of our fragrances are compliant with the International Fragrance Association (IFRA) standards, ensuring they meet global safety guidelines. - Natural and Synthetic: We use both natural and synthetic fragrance ingredients to create unique and pleasing scents while adhering to our strict safety standards. Xx, Team RŌZ
