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.

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)

"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)

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)
