"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."

"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!"
"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🤩"
"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."
"I have tried many clean shampoos and conditioners and FINALLY found one that works!! This stuff is amazing and leaves my hair feeling soft, shiny, and healthy! Highly recommend!!!"
"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!"
"Falling in love with Roz all over again — the scent is dreamy, the formulas are super lightweight, and the results are chef’s kiss. If you’re looking for high‑quality hair care that actually delivers, this is it."
"I like this shampoo and conditioner for my thick / dry hair use it a couple times a week. Leaves my hair soft but doesn’t weigh it down too much. Smells good too."
"The foundation shampoo and conditioner by far are the best around. I have highlights and my hair can be dry but this stuff makes it so soft and manageable!! I also got the hair serum!! My go to and it smells like heaven!! I will be a forever customer!!"
"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!"
"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 ❤️"
