"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."

"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."
"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🤩"
"My hair is soft and I felt very comfortable using heat after applying the product. Having a leave in that also protects against heat and de frizzes saves many steps."
"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!!!"
"Just started using the shampoo and haven’t had any issues. Hair smells good and feels soft after every wash. I can’t wait to see how things improve over time."
"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!"
"I love this shampoo and conditioner it smells amazing and hair looks and feels great."
"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."
