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. 

Cleanse with shampoo, then follow with conditioner, mid-lengths to ends. Let the conditioner sit for 2-3 minutes before rinsing. The shampoo cleans without stripping, and the conditioner puts moisture back where dry hair needs it most.

It's gentle enough to use daily. Cleanse with shampoo, then follow with conditioner, mid-lengths to ends. Let the conditioner sit for 2-3 minutes before rinsing. Add Salt Scalp Scrub once a week in place of shampoo.

Cleanse with shampoo, then follow with conditioner, mid-lengths to ends. Let the conditioner sit for 2-3 minutes before rinsing. It adds lightweight moisture that won't flatten your roots.

Cleanse with shampoo, then follow with conditioner, mid-lengths to ends. For deeper hydration, replace Conditioner with the Foundation Mask, or incorporate it as a weekly treatment.

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.

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.”

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.

The Foundation Shampoo/Conditioner

"Wow & wow again! My hair feels soft & luxurious! The smell of the Shampoo & Conditioner is a clean subtle smell. Very nice! After my hair air dried I added the Milk Hair Serum & I immediately noticed the “SHINE”! I can’t wait to try the Santa Lucia Styling Oil & the Willow Glen Pre-wash Treatment as apart as my routine🤩"

— Paula H. (5/5)

Smells great and works

"My hair is soft and I felt very comfortable using heat after applying the product. Having a leave in that also protects against heat and de frizzes saves many steps."

— Steven P. (5/5)

Best Products I’ve Used

"I use very nice products but was compelled to try Roz as it seemed different and effective. It is amazing and now has replaced my basic routine.

I love my hair again!

"I love my hair again! My hair is soft and manageable and just feels good. Even my hairdresser asked me what I was using because my hair felt so nice and had a light pretty scent to it.

Q&A

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
Hi I was wondering if the shampoo is fine for hair with an oily scalp?
Hi Katherine! Thank you for your question! Yes, our Foundation Shampoo is perfectly for use on hair with an oily scalp. It uses coconut surfactants to gently remove build-up and balance hair and scalp PH. Infused with our Botanicomplex™, the Foundation Shampoo also helps to promote scalp restoration and long-term protection against free radicals. Feel free to reach out to us at hello@rozhair.com with any other questions! Xx, Team RŌZ
