“My goodness, my hair loves this Foundation Shampoo and Conditioner. ‘Foundation’ is the appropriate name for this shampoo and conditioner, because it's truly the anchor to my routine—and I need a strong one because I put my hair through the wringer. I style it in all kinds of ways; naturally curly, blown-out straight, in a slick-back bun—the list goes on, and this duo ensures my hair is as healthy, happy, and hydrated as it can be. It literally makes my hair color richer, my curls more quenched, and my scalp feel fresh. With all the heat-styling I do, the moisture it delivers is key for me. The formulas are free of sulfates, silicones, and parabens, and I love that Rōz effectively balances the science and performance of haircare with a sense of ease and thoughtfulness. And that extends to the packaging, which is an aluminum bottle in the most beautiful shade of mint green meets blue slate. I could see those with thin or fine hair finding the conditioner slightly heavy, but the shampoo would be just fine. On top of it all, the scent is comforting yet fresh—it has zingy citrus and a nectar-like sweet fig, but also has vetiver and frankincense, which just smells like Laurel Canyon in Los Angeles to me (where founder Mara Roszak is from). Yes, I'm admittedly romantic about this product, and it's because it truly loves my hair.” —Shanna Shipin, senior commerce director

“My long hair is balayaged into a blend of gray and blonde—and it looks and feels so smooth when I use this shampoo and mask. It's not billed as a combo for color-treated hair, but it's gentle and moisturizing, so it certainly fits the bill. The shampoo suds up beautifully (I usually do two), and a dollop of the Foundation Mask is enough for my hair, which is currently almost-bra-strap-length (I comb it through, leave it in for a couple of minutes, then rinse). The citrus-y, fig-y scent is a joy in the morning, and the packaging is chic and understated without trying too hard to be sleek and fancy. I'm not saying I worked my recent bathroom reno around this duo; I'm just saying that light blue does look great in my new shower. If you have finer/thinner hair, you could use the regular conditioner instead of the mask,” —Jenny Bailly, executive beauty director
