On a damp Tuesday evening, under the cold fluorescent lights of a supermarket aisle, a woman in scrubs stood examining the shampoo section as if she were studying a medical chart. Patients had been asking her all day which product to pick, which formula to trust. Now, there she was, dermatologist coat folded over her arm, basket half-filled with tomatoes and yogurt, hesitating among dozens of bottles boasting promises of “ultimate repair” and “salon results.” She sighed, reached past the expensive glass bottle, and grabbed an unassuming shampoo from the middle shelf. Then she smiled—a quiet, satisfied smile that comes only when you’ve found something that simply works. “I’ll buy this until I’m 90,” she muttered to the confused man standing next to her. He chuckled, completely unaware that she was one of the country’s leading skin specialists.

The Simple Supermarket Shampoo a Dermatologist Trusts
The dermatologist in question is Dr. Léa Moreau, a French-trained skin expert who specializes in treating delicate scalps and fragile hairlines. At her clinic, patients come in with photos, ingredient lists, and half-empty bottles, hoping she’ll endorse their choices. When Dr. Moreau discusses shampoo, she does so like people talk about friendships—what lasts, what disappoints, and what quietly supports you without fuss.
Her favorite? A humble, under-$10 dermo-protective shampoo from the pharmacy-supermarket aisle—the kind you’d likely overlook because its packaging seems too plain. No glitter, no celebrity endorsements. Just a straightforward ingredient list and a promise of “frequent use.”
Dr. Moreau recalls the patient who inspired her search for a long-lasting, realistic shampoo recommendation: a nurse in her 40s with her hair tied in a tired bun, who said, “I wash my hair every day after work. I don’t have the time or money for salon products. Just tell me what to buy at the supermarket, and I’ll use it.” That statement stayed with her.
So, Dr. Moreau spent weeks studying the shampoo aisle like she would a clinical study—looking at surfactants, preservatives, fragrance levels, and pH. She tested the formulas herself, consulted her colleagues, and even gave samples to friends with sensitive scalps. One particular formula kept getting the same feedback: “My scalp doesn’t itch anymore” and “My hair feels clean but not squeaky.”
According to Dr. Moreau, the reason this shampoo works is refreshingly simple: Most scalps don’t need fancy oils or exotic plant extracts. They need mild cleansing agents, a balanced pH close to that of the skin, and minimal irritants. The shampoo she chooses is typically labeled “extra gentle,” “dermato-tested,” or “for frequent washing.” Inside, you’ll find light surfactants like coco-betaine, no harsh sulfates like SLS, and a fragrance that’s subtle, not overpowering.
Points out that the scalp is skin—not just the place where hair grows. Treat it like skin, wash it regularly, avoid harsh treatments, and your hair naturally looks better.
How She Uses It at Home—and What She Tells Her Patients
At home, routine is surprisingly minimalist. She keeps her favorite supermarket shampoo right at the front of the shower, next to a single conditioner for her hair’s lengths. She wets her hair thoroughly, then applies a small amount of shampoo—about a teaspoon—focusing on the scalp first, not the ends. She massages gently with her fingertips (never her nails), starting at the nape of the neck and working her way to the crown. When rinsing, she lets the foam run through her hair, rather than shampooing the lengths directly.
If she’s had a particularly sweaty day in the clinic, she’ll apply a second small amount of shampoo. No multi-step rituals, no weekly masks. Just this simple, consistent gesture.
When she shares this with her patients, many look a bit guilty. They confess they scrub aggressively because it “feels cleaner” or pour half the bottle trying to recreate a salon-level foam. Some even alternate between anti-dandruff and ultra-hydrating formulas, hoping to fix every issue in a single week. Dr. Moreau reassures them. “We’ve all been there,” she says, “the moment when you panic in front of the mirror, convinced you need a miracle product because your hair looks dull in poor bathroom lighting.”
Her advice? Start by calming your scalp, not attacking it. Use a gentle shampoo regularly, take photos weekly in natural daylight, and notice the changes over time—don’t judge your hair by how it looks after one wash.
Price Isn’t Everything
“I’ve tested countless shampoos in my career,” she says. “The one I keep rebuying is a supermarket dermo brand with a simple label, mild surfactants, and a price that doesn’t scare you. I’ll buy it until I’m 90 because I want something my patients and my own family can afford every week.”
- A label that says “gentle” or “frequent use” and mentions dermatological testing
- No strong sulfates like Sodium Lauryl Sulfate high on the ingredient list
- A short ingredient list that you can read in under 30 seconds
- A neutral or lightly soapy fragrance, not a heavy perfume
- A price that feels sustainable, not a once-a-year treat
Let’s be honest: nobody really sticks to a 12-step hair routine every single day.
Why “Boring” Is Actually the Most Luxurious Choice for Your Hair
There’s something comforting about the idea that the shampoo a dermatologist trusts isn’t hidden away in a salon but is sitting quietly next to the discounted toothpaste and family-size shower gels. When you cut through the marketing noise, the perspective changes. Hair care stops feeling like an emergency and starts to feel like a natural extension of your skin. You begin asking yourself different questions, like “Does my scalp feel calm?” instead of “Does my hair bounce like in a commercial?”
For many readers, this story will feel familiar: the rushed morning shower, the automatic grab of the same bottle every week because you don’t have time to read reviews, the quiet guilt when you see glossy advice claiming you’re “doing hair care wrong.” Maybe you’ve tried expensive products that smelled wonderful for three days, only to leave your scalp tight and flaky, or maybe natural shampoo bars left your hair tangled and impossible to manage.
Dr. Moreau’s favorite supermarket shampoo is almost a relief: it gives you permission to seek something that simply works—without drama, without extravagant performance claims.
Her statement—”I’ll buy it until I’m 90″—is less about the exact brand name and more about the philosophy: a product you can rely on, one that respects your scalp, doesn’t blow your budget, and doesn’t require you to reinvent your routine every season. For some, that will be the same dermo brand Dr. Moreau uses; for others, it might be a local equivalent with similar qualities. The key is to look beyond the shine of the bottle and ask yourself: Does this shampoo treat my scalp like skin? Does it fit into my real life?
That’s the type of sustainable beauty choice people trust for decades. The kind of product you can see on your bathtub ledge when you’re 90, still doing its job, without the need for applause.
