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
Foundation Shampoo
"I have been using a great shampoo, my hair salon just started to carry it. Its sulfate free and smoothes my curly course hair beautifully. I also use the Milk Serum and purchased for my daughter. Well done, Roz"
"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!"
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."
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."
Color me impressed
"I have tried so many shampoo and conditoners, but with a lot of fine wavy hair and an oily prone scalp, nothing ever seemed to work. This set has let me have nice day two hair ( a small miracle) and the smeel is lovely. Will be repurchasing."
I got hooked after trying the travel size
"Even that little bit was enough to entice me to buy regular size shampoo. I sure am glad I did. My soft waves and curls are full and keep their shape and all I need is to air dry."
"Love the product. Its a good lathering and great smelling shampoo. The conditioner is rich and creamy. The pump on the conditioner container never pumped and doesnt seal so its very hard to get the poduct out. Faulty pumps!!"
Such A Wonderful Product
"I’ve used Roz shampoo and conditioner for a while now, and each time I go to a hairdresser, they comment on how healthy my hair looks! This product is significantly better than ones I have tried before."
Fave shampoo and conditioner
"Feels and smells clean and love the natural fragrance (a welcome departure from the artificial smells and textures of other brands)"
