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. 

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.

Reviews

loved it!

"I tried Roz shampoo in our local salon + did cleansing treatment including hair scrub from Roz. so far experience is only positive, no itch after shampoo, conditioner is decently moisturizing (not a heavy cream texture) - works for my oily roots and long medium hair!"

Nargiz B. (5/5)

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)

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 purchased the mini set that gave me a great overview of the products. I have now replaced all with full sizes. The shampoo and conditioner is outstanding."

Mary C. (5/5)

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. I wash, condition, then use the Roz milk serum and the Roz styling serum, then blow dry my hair and it all falls into place. I love it!"

Annette K. (5/5)

Best Hair Ever

Maryann W. (5/5)

A lot of Hair and A lot of Love for Roz

"The refill option makes me so happy. Primarily because I am not adding new containers into the environment. Secondly, there are four girls in my family and we all love Roz products, thank you!"

suzanne m. (5/5)

Bitchin' shampoo

"I don't know what it is about this line, but it's everything my hair needed. This shampoo leaves my scalp feeling so clean, but not in a drying or sensory (cooling) way. I definitely recommend this with the conditioner, your hair will thank you ❤️"

Vanessa K. (5/5)

My 20+ year for hair care is finally over

"Finally a system that is gentle on thin hair and effective for an oily scalp! Menopause and an hormonal induced tumor have ruined my hair- it was always fine but I had density and a balanced scalp, no problems in my younger days. I have been trying everything I could to find a cleaning system for my hair- rinses, bars, no-poo's, custom, clinical backed- you name it. I have sunk thousands trying to find something that works. I finally have in Roz. After more than 20 years of searching and wasting my time, money and hope, I can finally fully endorse a product."

Maeve (5/5)

Love my hair

"Product is fabulous. Leaves my thin limp hair full of body. Regretfully shampoo bottle top did not pop up and worked- had to improvise with another bottle top… very cludgey. Oh well. Hope next order has a better bottle top."

Linda L. (5/5)

Love the foundation products

"Have been using the Foundation line for a few months now and I love it. My hair looks and smells fantastic."
