FAQ

We always say to listen to your hair here—there’s no one-size-fits-all. Most people find their sweet spot is 2-3 times per week, but if your scalp leans oilier, you can absolutely use it more often. It’s a gentle, sulfate-free formula, so it cleans without stripping, which makes it great for regular use.

In case it gives you a little trouble, here's a trick! Please first tighten the pump around the neck of the bottle—as if you are simply tightening the pump, as if it’s too loose. Then, push down on the top of the pump and twist counterclockwise to pop up.

Yes! The Foundation Shampoo is safe for both color-treated and keratin-treated hair. It’s sulfate-free and designed to cleanse gently while helping maintain the integrity of your color and treatments.

Reviews

"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."

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"

— Jill W. (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)

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."

— Jill R. (5/5)

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."

— Christine G. (5/5)
