Included: Foundation Shampoo, Foundation Conditioner
A hydrating conditioner, powered by rich peptides & ceramides, that smooths, hydrates, and detangles.
Why silicone-free?
Silicones can add immediate slip and shine, but some formulas may leave hair feeling coated over time. Foundation Conditioner is formulated without silicones, using peptides, ceramides, and avocado oil to deliver weightless hydration, softness, and easy detangling. Learn more about what silicones do in hair products and when buildup may matter in The RŌZ Guide.

"Keep a brush or comb in the shower. Detangle hair while conditioning to ensure even distribution and silky smooth strands. You may not even need to brush hair post shower!”

"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!"
"★★★★★ 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!"
"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."
"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."
"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!"
""your hair is so so soft!" my husband is delighted in my switch to ROZ products. Even with my weekly swim sessions the Shampoo has worked my scalp and left softness in it's wake. I'm hooked and my hubby thanks me for it."
"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."
"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."
"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"
