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.

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.

Reviews

"Terrible! I was super disappointed with this shampoo and condition! After hearing so many people promote it and talk about it with High praise I was super disappointed as a girl with oily hair. It did not get my hair clean. Would not recommend and wish I hadnt wasted my money!"

Courtney (1/5)

As someone who has fine,

"As someone who has fine, mixed curly-wavy hair that frizzes or flattens easily, I have spent a fortune trying to find products that hydrate my hair without weighing it down. Sometimes I had 4 different shampoo/ conditioner combos at a time in my shower (bless my husband for tolerating me hogging shower shelf space for so many years!). Enter Roz products. My search finally feels like it’s over. I waited to buy the refill bundle until I was sure this was the right product. This bundle is 100% worth the price for anyone with similar hair to mine, and it smells like heaven!"

Shannon W. (5/5)

Love this combo

"I have tried what feels like every shampoo and conditioner out there over the years. I honestly don't think I have ever loved both the shampoo and conditioner of any brand. So this is a first! It feels made for my post-menopausal hair--clean but not drying, moisturizing but not too silky or heavy. Works great with my highlights. I could pinch myself, my quest is over!"

Susan D. (5/5)

My hair has changed after

"My hair has changed after chemo treatments for a while. Curly now in the back and straight everywhere else! But, the conditioner has softened it overall without limpness. A small amount works best for me; followed by your Air Spray and Thickening Mist. I know I am not your demographic but I and my hair am grateful for your line of products."

Sharron C. (5/5)

Love it all.

"I absolutely love the shampoo and conditioner as well as this milk soon. I have slightly baby hair and this works so well when I first wake up in the morning or right after I questioned it. It gives it definition."

Lisa B. (5/5)

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)

Mary (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)
