Every few months a client drops into our chair at Sølvi and says some version of the same thing. My ends feel like straw, my color faded fast, and nothing I bought at the drugstore fixed it. When the hair is genuinely damaged, we keep reaching for one wash off our shelf more than any other. The Davines NouNou Duo. Here is our honest, behind-the-chair take after using it on real heads of hair through a full Boise winter.
What the NouNou Duo Actually Is
The NouNou Duo is the shampoo and conditioner pairing from the Davines Essentials range, built specifically for damaged hair. It runs $33.30 for the set, which puts it squarely in the salon-quality tier without climbing into the eye-watering luxury bracket. The formula leans on rich emollients, which is the technical way of saying it coats and softens strands that have been beaten up by bleach, heat, or time. You can read the full product details on our NouNou Duo page.
We reach for this on hair that is chemically treated, over-processed, or just very dry. If you have lived in Boise for a winter, you know our air is brutally dry, and that low humidity pulls moisture out of already-fragile hair faster than most people expect.
How It Performs Behind the Chair
The first thing you notice is the lather. It is creamy and dense, closer to a treatment than a typical shampoo. Clients regularly comment that it feels like a spa moment, and that matters, because a product that feels good is a product people actually keep using at home. Consistency is half the battle with damaged hair.
On the towel-dry, we see real slip. Detangling is easier, breakage during combing drops, and the hair takes blow-drying with less frizz. Over a few weeks of regular use, the mid-lengths and ends look less brittle and hold their shape better between appointments. It is not a miracle that rebuilds split ends. Nothing washes-out repair does that. But as a daily maintenance pair, it does the job it promises.
Who It Is Not For
Here is the honest part. The NouNou Duo is rich, and rich is exactly what fine, oily, or already-healthy hair does not need. If your hair is in good shape and tends to go flat or greasy by the end of the day, this duo will likely weigh it down and leave roots looking limp. We have had clients love it for a season of repair, then graduate to a lighter Davines line once their hair recovered. If you fall into that fine or oily camp, talk to us before you buy, because the wrong wash is wasted money.
The Weekly Upgrade
The shampoo and conditioner do most of the work, but for hair that is severely fried, we often add the Nounou hair mask as a once-a-week treatment. The mask is a separate purchase, not part of the duo, so do not expect it in the box. Used together, the duo handles your daily routine and the mask delivers a heavier deep-conditioning hit on wash day. For most damaged hair, the duo alone is plenty to start.
Our Verdict
For damaged, color-treated, or sun-and-wind-beaten hair surviving an Idaho climate, the NouNou Duo earns its spot on our shelf. It is a genuine repair-focused wash at a fair price, and our stylists use it on our own hair. We just want you matched to the right product, not the most popular one. If you are unsure, that is what we are here for. Take a look at our salon services to see how we pair retail with in-chair treatments, then book an appointment at our downtown studio at 104 S Capitol Blvd. We will look at your hair, feel its condition, and tell you honestly whether NouNou is your match.
