This bestselling cleanse day duo is now available in 900mL salon sizes.

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.

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.

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.

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.

Love these products!

"I tried Roz on a whim, best hair decision ever! The products smell amazing, they make my hair soft and easy to manage. I bought the shampoo, conditioner, hair milk and oil. I love them all! I had previously been using another brand for the last 6 or 7 years, it was time for a change, and I am so glad I did!"

Love the shampoo and conditioner

"Finally found great hair care for my 16-year-old daughter with very thick gorgeous hair."

manoj k. (5/5)

Prepare for compliments!

"I didn’t realize I would get compliments just from changing my shampoo and conditioner. I’ve had multiple people ask what I’m doing differently and that’s it - I’ve made no other changes. My hair looks healthier and I’m told more vibrant. I’ve noticed it feels softer and I have significantly less frizz. I’m very pleased with this purchase."

MarieAlyse P. (5/5)

Amazing results!!

"I’ve been using the RŌZ shampoo and conditioner for a few weeks, and the frizz in my hair is completely gone. My hair feels smoother, more manageable, and less dry without feeling heavy. It also looks healthier and more polished overall."

Rusudan P. (5/5)

I have tried so many

"I have tried so many expensive shampoos and conditioners. None compare to the smooth lustrous shine I get from using this product. I love this shampoo and conditioner!"

Evelina L. (5/5)

Love it! My friend recommended

"Love it! My friend recommended it to me. Thank you!"

Natalia W. (5/5)

Ideal size & value!

"I’m obsessed with these value sized bottles! I recently started having to share my Roz shampoo and conditioner with my new partner in their shower so more volume per bottle has proven to be of utmost value. Unfortunately the sheer weight of this size means the new pair was too heavy for my boyfriend’s cheap shower caddy and the beautiful aluminum bent when the bottles almost immediately fell from the wall. 😩 They now live safely on the floor but I’ll for sure eventually purchase another set to replace and keep these beauties in top shape! For now though, the refill subscription + salón sized bottles are by far the best bang for your buck option that ensures I can continue to afford to use these top quality products on a regular basis and maintains both my hair and my wallet happy and healthy. 🥰 This line literally transformed my scalp (and therefore ends) from dingy to vavavoom+(!) within the first two weeks of use and won me over as a forever loyal customer in the process. I’ve turned everyone that’ll listen to me go off about it o to it and that’s now MANY people since I get complemented on my “signature” scent whenever I hug or kiss anyone all the time and I always have to chalk it up to my Roz haircare routine alone! Thanks for creating these and making them accessible for me in Puerto Rico, Roz!"

Finally found…

"The perfect shampoo and conditioner. Scent is lovely but not overpowering and cleans my hair without weighing it down. It actually lathers. Don’t hesitate just get it. I’ve tried many shampoos and this outshines them all ;)"
