"My daughter's hair has never felt softer! She has platinum blonde, super long hair, the struggle has been real, until her mom bought her the Roz Shampoo and Conditioner. She is obsessed, loves the lovely light scent and the bounce and softness that Roz gave her. Highly recommend!"
"My hair hasn’t looked this great in years! blow-dry and most think I’ve straightened it! It Calms my frizz and is So healthy and shiny! ROZ Smells so light and wonderful. I will splurge on the leave-in next!"
"The scent of Rōz is absolutely delightful and leaves my hair soft, smelling wonderful and full of volume. I appreciate how lightweight it is, and how I can control it by adding some clarifying washes and/or deep conditioning in addition to the standard shampoo/conditioner. I can't get enough of Rōz and so far, have nearly everything in the collection! So good!"
"I am the pickiest person when it comes to hair products. Super skeptical. Honestly, had it not been for Lily Collins, I would have kept scrolling. That was just great marketing. All kidding aside, It’s totally worth it. Great product 10/10."
"★★★★★ This has easily been one of my favorite shampoo and conditioner duos I’ve used in a while! My hair actually feels clean after using the shampoo, and the conditioner leaves my ends feeling soft and moisturized without weighing my hair down. The scent is also really nice—fresh and clean without being too strong. Definitely a duo I’ve been enjoying!"
"When I took a pump I was worried the scent would be too strong and that the shampoo would be too harsh but its perfect. It gets rid of build up and gives me a perfect reset without stripping moisture or giving me an itchy scalp. I have fragrance allergies but it didn't make me break out. I'm so glad I found this shampoo for my very fussy hair/skin!"
"Love the shampoo and conditioner it makes my hair feel very silky and clean and smells wonderful. Highly recommend"
"Very pleased with their products. I like the way my hair looks and feels after I use the shampoo and conditioner. I just ordered the air thickening spray and it does seem to add some volume to my hair."
"Just purchased. My daughter is obsessed with the products and I recently started using the shampoo, conditioner and milk rinse. So far, so good! It leaves my hair with a nice texture and I am looking forward to seeing additional long term results as I continue to use the products."
"Wow! What a difference! I was afraid of the "one size fits all" but because of how my hair responded - frizz gone, waves so smooth and hair so shiny and soft - I am recommending this to everyone!"
