"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."

"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 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!"
"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 ❤️"
"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."
"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."
"Finally took the plunge and bought this after getting my hair done at a salon with it. Doesn’t disappoint and smells great."
"My hair smells amazing and is so soft! I have fine curly —this combo moisturizes my hair without weighing it down. The fragrance is pure heaven"
