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."

Reviews

Love the Scent & How My Hair Feels

"★★★★★ 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!"

— Abigail M. (5/5)

just wow for this 2A soft curl girl

"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!"

— Melissa W. (5/5)

Amazing

"I have been using the foundation shampoo, conditioner, styling oil and milk serum for over 6 months and I have noticed a drastic change in my hair. Loosing less hair, hair always looks hydrated and can go longer between wash days without my hair looking oily."

— Heather H. (5/5)

"Absolutely love this hair serum! ⭐️⭐️⭐️⭐️⭐️ It has helped so much with my little flyaways and frizz, and my hair already feels softer and healthier in one wash. I’m excited to keep using it and see even more results! Their customer service is also amazing, truly outstanding all around. Highly recommend!"

— Christopher (5/5)

Best products for silky smooth hair!

"I ordered the foundation shampoo and conditioner, foundation mask, milk hair serum, and santa lucia styling oil on the 14 day "try before you buy" promo. I'm so glad I did! Since turning 40, I have struggled with coarse and unruly hair that was dull and would no longer hold a curl (even though I used to have Topanga level hair when I was younger). With the first wash, I could tell the difference. As I rinsed out the foundation mask, I recall thinking "my hair has never felt this smooth". The milk serum and styling oil make it even better. I will definitely be purchasing more products and look forward to seeing how my hair continues to improve."

Shampoo Hydration

"I am in love with ROZ product. MY first purchase was the Milk Hair serum, and from there I was sold. I have thick frizzy hair. The Milk Serum, work wonders for my ends of the hair. Leaves my hair very soft. I then purchased Santa Lucia Styling Oil, for after I dry my hair, and my hair feels silky. I read about the hydration shampoo and had to try it. I moved to Denver a little while ago, and the climate is dry, and the water was making my hair ends very dry. With the shampoo I feel my hair is getting the care it needs. I really love this product. I have bought many hair products, but ROZ really is the best. I am very happy with this hair product, and I highly recommend it."

— Alexandra p. (5/5)

"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)

My search is over!

"I’ve been long searching for a gentle shampoo + conditioner that is cleansing, without stripping & moisturizing, without being heavy (respectively). It’s a pleasant experience using these & I especially enjoy how well the shampoo lathers. The packaging also looks really pretty in my shower."

— Kathleen J. (5/5)

Love ROZ

"I love ROZ! I always look forward to hair wash days. I have thick, wavey hair and ROZ is like my clarifying shampoo. It’s a good gentle clean that leaves my hair squeaky clean. The scent does vary and it does it have a shelf life so don’t let it sit around for more than 6 months."

— Delia G. (5/5)

I love these products! I

"I love these products! I have received many compliments on my hair since I have been using them. I will definitely continue to use all the products. My hair is smoother, healthier, and it has more volume."

— Michael D. (5/5)
