The best shampoos for thinning hair in 2026, according to testers and dermatologists
A $52 wash topped our testing, but science-backed drugstore staples are right behind. Real users plus derms explain what a wash can (and can't) fix.

Let's get this out of the way early: shampoo — even the best shampoo for thinning hair — probably won't grow new hair. But it can treat scalp problems, like dandruff and oiliness, that worsen shedding. "Scalp health is an important part of healthy hair growth because hair follicles are embedded within the skin," explains Dr. Sejal Shah
, a board-certified dermatologist in New York City.
That helps explain why several medicated shampoos made our list. "Dermatologists love anti-dandruff shampoos — even for people who don't have dandruff," says Dr. Ronda Farah
, a board-certified dermatologist at the University of Minnesota. They help "manage oil, buildup, yeast and inflammation on the scalp." Just remember, improving scalp health is "different from stimulating dormant hair follicles," Shah says — and a different promise than the one sold on many of the bottles.
So yes, some shampoos for thinning hair can earn their place in your shower. To find out which, we gave five shampoos to women with ongoing hair thinning for three to four months, tracking their shedding and density ratings alongside photos. Then dermatologists and a cosmetic chemist helped us make sense of the results. Two shampoos came out ahead. Three didn't make the cut. We rounded out the list with four expert-backed picks for needs our testing didn't cover.

The best overall shampoo for thinning hair
How often she used it:Nearly every wash| Density:1 → 3 | Shedding:Less | Confidence itworked: 5/5
Density is the tester’s before-and-after rating on a 1–5 scale. Confidence is how sure she is that the product caused the change.
🏆 Also won:One of the Best products for thinning hair
Our tester, in her 20s, had spent at least a year styling her hair to hide thinning at her hairline. "Whenever I wear my hair up, you can see bald spots around my forehead area," she said. Four months into using Vegamour, her shedding had dropped and her density rating had climbed from 1 to 3. "I really noticed a difference when I went back to look at my starting pictures," she said. "It's done exactly what I hoped for — promote new growth and thicken the hair I already have." That’s her assessment, though our testing can’t establish whether the shampoo stimulated new growth.
Reality check: She still sees some scalp.Even so, she calls the change a "dramatic improvement." Vegamour’s star botanicals, rhubarb root and Japanese beautyberry, have barely been studied in people, so it’s hard to say what drove her results. She used it for nearly every wash and "made sure to really massage my scalp for several minutes with the shampoo," which kept the formula on her scalp longer than instructed.
Why we’d buy the shampoo alone:The set costs $94, but our tester gave the credit to the shampoo. "The conditioner was just OK," she said, and she blamed it for making her hair greasy faster. We’d put the $52 toward the shampoo and stick with a conditioner you already like.
- Baby hairs and filled-in patches by month 2
- Noticeably less shedding
- No irritation on our tester’s sensitive skin
- Pricey for a shampoo
- Little research on key ingredients

How often she used it:Once weekly | Density:2 → 3 | Shedding:No change | Confidence it worked:4/5
Density is the tester’s before-and-after rating on a 1–5 scale. Confidence is how sure she is that the product caused the change.
🏆 Also won: Best dandruff shampoo
An oily scalp, thinning hair and postpartum shedding topped the issues our tester, in her 30s, came to us with. "I lose so much hair on a daily basis that it's actually clogging my drains," she said.
Enter Nizoral. It’s a dandruff shampoo first, but its anti-fungal ingredient, ketoconazole, is also being studied for pattern hair loss . Our tester used the 2-in-1 shampoo and conditioner, and three months in, she noticed fuller-looking hair around her hairline and temples. "I see less skin," she said. "I also feel like my scalp is less itchy and I have fewer flakes."
Reality check: Her drain wasn’t getting a break."My hair still falls out a lot. I expected that it would help more with that," she said. She also used it less than directed: once a week, not the 2-3 times used in most ketoconazole studies. Dr. Jessica Burgy , a board-certified dermatologist in Columbia, S.C., isn’t surprised she didn’t see more: Ketoconazole isn’t considered a treatment for postpartum shedding. Instead, it’s “an excellent adjunct” to hair loss treatment.
Why we’d buy the shampoo alone:Our tester tried the 2-in-1, but its conditioner was “NOT enough for my hair by itself.” When she skipped her own conditioner, “my hair was a frizzy mess,” she said. Farah prefers separate products too. “You need conditioner to be dedicated to hair shaft moisturizing and cuticle protection,” she says. Give your scalp the shampoo and your ends the conditioner you already love.
- Denser hairline and less visible scalp after 3 months
- Less itching and flaking
- Published research behind it
- Shedding stayed her biggest complaint
- Can be drying, may fade color faster
- Avoid during pregnancy
Head & Shoulders
Not tested by our panel. Recommended by our dermatologists.
If Nizoral doesn’t work for you, the American Academy of Dermatology (AAD) — and our experts — suggest alternating between two dandruff shampoos with different active ingredients, including pyrithione zinc, the flake-fighter in Head & Shoulders. In one study , both 1% pyrithione zinc and prescription-strength 2% ketoconazole significantly reduced dandruff, though the Rx had a slight edge.
For textured or curly hair,Farah recommends Head & Shoulders Royal Oils anti-dandruff shampoo . She uses it herself. “Curly and coily hair tends to be drier because the hair’s natural lubricant sebum doesn’t travel as easily along a curved hair fiber,” says Kelly Dobos , a cosmetic chemist and adjunct professor of cosmetic science at the University of Cincinnati. This one adds coconut oil and a conditioning polymer called polyquaternium-10, which she suggests looking for in a medicated shampoo for curls. It’s also sulfate-free. "It’s a less aggressive shampoo, helping to limit damage to the hair shaft," Farah says.
- Gentle enough for frequent use
- Pyrithione zinc has research behind it
- Slightly less effective than ketoconazole in one study
- Can feel a bit drying

🏆 Also won: Best for itchy scalp
Selenium sulfide, the active ingredient in Selsun Blue, works on two fronts: it "reduces fungal growth and also slows the turnover of scalp skin cells, making it useful for more persistent scaling and flakes," Dobos says. "Persistent"is key here: "left untreated, it can contribute to increased shedding,” says Dr. Efe Kakpovbia , a board-certified dermatologist and assistant professor at NYU Grossman School of Medicine.
Farah keeps Selsun Blue in her lineup, and Yahoo’s beauty team named this moisturizing version the best overall dandruff shampoo . Medicated shampoos can often leave hair dry, but this one includes aloe and dimethicone, a silicone that smooths strands.
- Adds moisturizing aloe and dimethicone
- Tackles yeast and skin-cell turnover
- Yahoo’s beauty team’s top dandruff pick
- Uses a sulfate cleanser
- Little research on hair loss specifically
- Silicone may weigh down fine hair

🏆 Also won: Best bonding shampoo
Not everything that looks like thinning is actual hair loss. "It can be difficult to distinguish breakage from true hair loss on your own," Kakpovbia says. And the wrong shampoo can make it worse: "Using harsh shampoos — particularly those with strong detergents or sulfates — can contribute to dryness and breakage," she says.
Verb Bonding, Yahoo's beauty team’s pick for brittle, damaged hair, takes a gentler approach. It’s sulfate-free, and its main cleansers are on the milder end. It’s also designed to leave conditioning ingredients behind, which Dobos says can "improve combability and leave hair feeling smoother." Those include moisture-attracting glycerin and silicones that help reduce friction — both ingredients Burgy recommends for dry hair.
The brand’s main selling point is a "bond-repair" complex, but there’s no independent research behind that claim. Buy it for the gentle, moisturizing formula. Then use conditioner after every wash, which the AAD notes "reduces breakage and split ends."
- Sulfate-free
- Includes glycerin and silicones for dry hair
- Yahoo’s beauty team’s pick for brittle, damaged hair
- Helps with breakage, not shedding
- Contains small amount of isopropyl alcohol
- May weigh down fine hair
Shampoos we tested that didn't make the cut
-
Mielle Organics Rosemary Mint Strengthening Shampoo :Our tester, in her 30s, noticed less shedding, some baby hairs and easier detangling, but ultimately reported "not much growth." She used it only once every two weeks, limiting the number of applications during testing.
-
KeraFactor Scalp Stimulating Shampoo and Conditioner :A cleaner scalp was the main takeaway for our tester in her 60s. Her density rating stayed at 1 out of 5. "It's a fine shampoo and conditioner, but it doesn't really promise growth, and I didn't see any," she said.
-
Pura D'Or Gold Label Anti-Thinning Shampoo and Conditioner : "It worked like any other shampoo, but did nothing to prevent shedding or hair loss in the shower," said our tester, who is in her 50s. Her density held at 3 out of 5, and she rated her overall result a 1.
What a shampoo can (and can't) do for thinning hair
A shampoo spends a minute or two on your scalp before it goes down the drain, so it's not the ideal tool for growing hair. Here's what it can realistically do.
-
Treat the scalp.Medicated shampoos can address dandruff and scalp inflammation that contribute to shedding.
-
Reduce breakage.Fewer snapped strands can make hair look fuller. "Conditioning ingredients that genuinely reduce breakage are often the most successful," Dobos says.
-
Make hair look thicker for the day.Volumizing formulas lift strands with ingredients such as film-forming polymers and hydrolyzed proteins. The effect washes out. For more on keeping fine hair from falling flat, see our guide to the hair-washing mistakes that can make hair look thinner .
That doesn't make shampoo a proven hair-regrowth treatment. "True hair shedding is usually driven by biology inside the follicle, and those are much higher scientific and regulatory bars to clear," Dobos says. Topical minoxidil , aka Rogaine , is the only OTC drug FDA-approved to regrow hair.
How to use a medicated shampoo so it works
-
Put it on your scalp."That's the target, not the hair shaft," Burgy says.
-
Wear braids or locs?Try a nozzle applicator bottle to get the shampoo onto your scalp.
-
Leave it on.A too-quick rinse-out tops Burgy's list of common mistakes. Follow the bottle's directions or your dermatologist's instructions for how long to leave it on.
-
Condition your ends only.Apply conditioner on the mid-lengths and ends of the hair to minimize dryness, Burgy says.
-
Rotate your shampoos.Alternate shampoos to "keep the scalp microbiome guessing," Farah says. It also makes medicated shampoos easier to stick with. "Rotation can be a way to balance efficacy and cosmetic elegance," Dobos says.
-
Give it time."At about 3 months, many people notice improvements in scalp symptoms first, like less itching, flaking, redness and oiliness," Burgy says. "Some may also notice reduced hair shedding, but visible thickening is often still subtle."
How we tested shampoos for thinning hair
Yahoo Health matched nearly 20 hair-loss products with volunteers experiencing real thinning, and five products were shampoos. Each tester used the shampoo (or a shampoo and conditioner) for 3-4 months — some as directed, others went a little rogue. For example, our Nizoral tester used her shampoo less often than directed. Our testers also completed a baseline intake and surveys at the start, midpoint and end, and took photos along the way. They rated their shedding and density on a 1-to-5 scale and told us how easy the product was to use, how confident they were that it caused their results and whether they'd recommend it.
All results are self-reported; they can't prove a product worked, which is why we also asked dermatologists and a cosmetic chemist to explain what our testers saw. Our dermatologists said hair treatments can take six months or more to judge, longer than our testing period.
We chose our four untested picks based on their ingredients, our experts' guidance and Yahoo's beauty team testing.
FAQs
Is a sulfate-free shampoo better for thinning hair?
Not automatically. Harsh cleansers, sulfates among them, can leave hair dry and more prone to breakage, Kakpovbia says. But "consumers sometimes interpret 'sulfate-free' as meaning 'extra gentle,' and that's not always true," Dobos says. Many sulfate-free shampoos use other strong cleansers. A better test is how your hair feels: if it's dry, rough or tangles easily after washing, try a gentler formula. Several medicated shampoos on our list, including Nizoral, do contain sulfates. Since you're using them only a few times a week, and following with conditioner, that's usually not a reason to skip them.
Will a shampoo help with postpartum shedding?
Probably not. Postpartum shedding happens because "many hairs shift into the resting phase after pregnancy-related hormones normalize," Burgy says, so shampoos, even those that contain ketoconazole, won't significantly change the course of shedding. It usually resolves on its own over several months. But pregnancy can also "unmask" underlying pattern hair loss, she says. If shedding hasn't let up, see a dermatologist.
What's the difference between anti-dandruff ingredients?
They tackle different parts of the same problem, Dobos says. Ketoconazole and pyrithione target the yeast associated with dandruff, while selenium sulfide also slows skin cell turnover to help with stubborn flakes. None of them grows hair, but "improving scalp health may be beneficial for people experiencing shedding associated with dandruff or dermatitis," she says.
How often should I use a medicated shampoo?
It depends on your goal. "If you're treating mild dandruff or maintaining seborrheic dermatitis after it's under control, once-weekly use is often enough for maintenance," says Burgy, who notes that, for thinning, you're usually asked to aim higher. "Most of the available studies have used ketoconazole 2–3 times per week." If that dries your hair out, she suggests alternating with a gentle moisturizing shampoo "rather than reducing it all the way down to once weekly."
Should I see a dermatologist for hair thinning?
If your hair loss is sudden, patchy or getting worse quickly — or comes with scalp pain, itching or scaling, see a board-certified dermatologist before buying anything. "Hair loss has many causes — including iron deficiency, thyroid disease, autoimmune conditions, postpartum changes and medications," Burgy says, and the right fix depends on the cause.
