Fancy light-therapy devices, scalp serums, and vitamins often get the spotlight when it comes to combating hair loss—but don’t overlook the best conditioners for thinning hair. I’m a 36-year-old shopping editor who reports on hair-growth products—many of which I’ve tested on my own shrinking follicles. In my quest to understand what treatments actually work, I spoke with board-certified dermatologists, trichologists, and hairstylists to learn about the root causes (groan) of reduced fullness, and worked with a panel of women and men to test the most highly recommended formulas.

Unlike regular conditioners, which often focus solely on moisture, these formulas are designed to boost volume, strengthen strands, and improve the look of thinning hair. “Some can be very effective at supporting hair growth and retention, especially when used alongside targeted treatments and supplements,” says Dendy Engelman, MD, FACMS, FAAD, board-certified cosmetic dermatologist and Mohs surgeon at the Shafer Clinic in New York City.
Similar to shampoos for thinning hair, the best conditioners for hair growth won’t work miracles overnight—but the right one can leave it looking noticeably healthier and more substantial with consistent use. Below, find the top formulas we’ve tested, recommended by experts, and reviewed by people experiencing everything from aging and postpartum shifts to stress, styling damage, and hormonal changes.
How we tested conditioners for thinning hair
AccordionItemContainerButtonLargeChevron
We recruited a panel of men and women to test 27 of the most highly recommended conditioners for thinning hair, including expert picks and bestsellers. Each tester either already owned or was assigned one product and used it consistently for at least six weeks. This amount of time was long enough to assess changes in volume, texture, and overall hair quality, based on guidance from the dermatologists and trichologists we consulted. In many cases, testers used the conditioner alongside its matching shampoo from the same brand, following expert advice that the formulas often work best as a system.
Participants followed the product’s directions and tracked shifts in shedding, manageability, and the appearance of density over time. They also rated each formula on scent, texture, ease of use, and overall value—factoring in how long it lasted and how well it performed for the price. Their feedback helped determine which conditioners earned a spot on this list and how each one was categorized.

1. Best Overall: Aveda Invati Ultra Advanced Thickening Conditioner for Thinning Hair

Aveda Invati Ultra Advanced Thickening Conditioner for Thinning Hair (6.7 fl. oz.)
Amazon
Nordstrom
Best for: All hair types, especially medium to thick hairSize: 6.7 fl oz.Key ingredients: Natural botanicals and oils, oat bran, caffeine, tocopherol (vitamin E)Fragrance: Herbal, woody
- What we love: Adds noticeable volume; strengthens without weight; silicone- and sulfate-free
- What could improve: Pricey for one bottle; not best suited for fine hair
This dermatologist-recommended formula is designed to instantly thicken the look of thinning hair while supporting long-term strength. “It’s a great detangler and using it regularly strengthens hair,” says Jodi LoGerfo, DNP, APRN, FNP-BC, a doctor of nursing practice and family nurse practitioner certified in dermatology. “I think it makes hair look thicker by plumping it—probably by increasing the diameter of each hair.” Aveda’s botanical plumping blend includes ingredients like natural oils and caffeine that invigorate the scalp. The texture feels rich but not heavy, and it leaves hair looking fuller even after a quick rinse.
Our tester says: “I’ve been doing everything I can to revive my thick head of hair since I noticed a significant amount of shedding and thinning at my temples in my late 20’s, but not even my daily biotin vitamin has provided the aesthetic improvement I noticed after less than a month of using Aveda’s Invati Ultra Advanced line,” says Glamour contributor Emily Tannenbaum. “The thickening conditioner is the real star of the show. After just a couple uses, I noticed a significant decrease in shedding, which is great, but I also noticed that my ponytail felt thicker as I rinsed out the product. At first, I thought my hair was just retaining more moisture, but I definitely feel the same thickness as I run my fingers through my hair right now. Plus, my hairline is starting to look more full in photos.”

Virtue Flourish Thickening Conditioner (6.7 fl. oz.)

Best for: Fine hairSize: 6.7 fl. oz.Key ingredients: Keratin, peptides, probioticFragrance: Botanical
- What we love: Strengthens without heaviness; improves shine and manageability; safe for color-treated hair
- What could improve: Pricey
Designed to support fragile, breakage-prone hair, Virtue’s conditioner uses ingredients that boost volume and resilience. “It contains keratin and peptides, as well as a probiotic, which could be super helpful for thinning hair,” says Dr. LoGerfo. Marie Nino, a professional hairstylist based in New York City, recommends Virtue Flourish’s shampoo and conditioner set for reinforcing strands without leaving them feeling coated or crunchy. Our tester—who used it once a week—saw shinier, less frizzy, and more deeply conditioned hair after just a few uses, with family members even noticing the difference.
Our tester says: “My hair looks smoother—and a lot less damaged—after using this conditioner once a week,” says Glamour tester Jenna Clark. “It’s easy to run a brush through my hair when I blow-dry it, thanks to the detangling quality. I’ve also noticed extra shine. The conditioner has a lighter scent than the shampoo, which I appreciated. While the bottle is on the smaller side, it didn’t affect how well it worked. My family even commented on how much healthier, more hydrated, and voluminous my hair looked.”

Monday Haircare Volume Conditioner (12 fl. oz.)

Best for: All hair typesSize: 12 fl. oz.Key ingredients: Ginger root extract, panthenol, coconut oilFragrance: Floral, slightly sweet
- What we love: Hydrates dry strands; very affordable
- What could improve: May not reduce shedding on its own
This under-$10 conditioner proves you don’t need to splurge to start addressing thinning hair. It’s an easy entry point if you’re unsure where to begin: The lightweight formula rinses clean, adds subtle volume, and leaves hair feeling softer and healthier—without a big investment. While it may not dramatically reduce shedding on its own, our tester found that the drugstore product noticeably improved softness, bounce, and manageability, with a scent she couldn’t get enough of.
Our tester says: “Since incorporating this conditioner into my hair wash routine twice a week, my hair has felt significantly more hydrated and healthy, even for days after washing,” says Glamour tester Bailey Gann, who has thick, dry hair. “The formula is easy to rinse out (no heavy residue!), yet still leaves my hair feeling soft and smooth—not to mention the smell is incredible (do they make this a body wash?). I didn’t notice a major change in shedding, but the boost in volume and overall hair health made me want to wear my natural hair down more often instead of keeping it up or slicked back.”

Best for: All hair typesSize: 8 fl. oz.Key ingredients: Marula oil, baobab oil, murumuru butter, red clover, mung bean, Karmatin (vegan keratin)Fragrance: Herbal, citrus
- What we love: Strengthens curls; reduces shedding; vegan formula
- What could improve: Fragrance isn’t for everyone
Formulated with plant-derived ingredients like marula oil, baobab oil, and murumuru butter, Vegamour’s Gro conditioner is designed to smooth, moisturize, and nourish thinning hair without leaving buildup. “It contains phytoactives like red clover and mung bean, plus a vegan keratin called Karmatin that can strengthen damaged, fine hair,” says Kseniya Kobets, MD, a board-certified dermatologist and director of cosmetic dermatology at Montefiore Einstein Advanced Care. Dr. Logerfo says that while the product is not especially volumizing, it “really conditions and hydrates damaged, thin hair.”
Our tester says: “I’ve been using the Vegamour shampoo and conditioner for about three months now, and my hair feels noticeably stronger and fuller—especially my curls,” says Glamour tester Canyon Silliman, who has dealt with hair loss and scalp dryness for the past four years. “If I shower before bed, I wake up with even more volume, like my hair took steroids while I slept. I don’t see nearly as much shedding, and I get great volume even a couple of days after washing. The only downside is the scent—it’s not bad, just not my favorite—but otherwise I’d absolutely recommend it, especially for men. My girlfriend has never complimented my hair more.”

Best for: All hair typesSize: 8.5 fl. oz.Key ingredients: Flax protein, biotin, panthenol, willow barkFragrance: Citrus
- What we love: Thickens dry, color-treated hair; adds bounce and softness
- What could improve: Pricey; takes effort to spread evenly
From the brand known for our favorite eyebrow and eyelash growth serums, this thick, citrus-scented conditioner uses ingredients like biotin and flax protein to support hair strength and fullness. Our tester, who has dry, color-treated hair, noticed softer texture and more volume after just two weeks of use—enough to reconsider heat styling. While the creamy formula takes a little effort to distribute evenly, it left her hair looking noticeably healthier.
Our tester says: “I’ve been using the RevitaLash Thickening Conditioner for two weeks, and I am thrilled,” says Glamour tester Charlotte Twine. “My hair is now a completely different texture than it was just a few days ago—full, bouncy, soft, and thick to the touch. Since my hair now looks so much fuller, and seems to keep a curl better, I’d like to see if I can try using a curler. The conditioner has a zippy citrus-y scent and is pretty thick in consistency. You have to work a little to make sure the product gets spread from scalp to tips. The price is kind of high, but I’m motivated to keep using this product for a while.”

This conditioner is part of BosleyMD’s Revive system, formulated specifically for visibly thinning hair. It’s full of plant-derived ingredients like sunflower seed oil for moisture and UV protection, nettle extract to support healthy strands, and fortifying proteins to improve strength and manageability. Our tester found it easy to distribute and said it paired especially well with the matching shampoo. She also noticed less hair shedding in the shower and appreciated that the clean scent faded once her hair dried.
Our tester says: “The Bosley conditioner has a lightweight texture that was easy to work through the ends of my hair,” says Glamour tester Marie Provence. “It paired really well with the shampoo—nicely balanced. I noticed less hair fallout in the shower than I usually experience with other products. The scent was pleasant straight from the bottle but faded completely once my hair dried, which I liked. It delivered on its promises: my hair felt more voluminous while still managing to tame frizz. Like the shampoo, this one’s a keeper in my hair care routine.”

Best for: All hair typesSize: 8.4 fl. oz.Key ingredients: Rosemary oil, plant proteins, ceramidesFragrance: Herbal, rosemary
- What we love: Boosts shine; hydrates without heaviness; fresh, subtle scentWhat could improve: On the pricier side; pump can get stuck
The hero ingredient in this fresh-smelling conditioner is rosemary oil, which experts say can stimulate blood flow to the scalp and support a healthier hair-growth environment. The texture of the formula is balanced and pairs well with the brand’s matching shampoo. Our tester, who has dry, wavy hair prone to frizz, found that the combination helped boost hydration and shine without any residue or weight. She also noticed a healthier-feeling scalp with continued use.
Our tester says: “This hair conditioner is a nice consistency that is not too heavy or too light and has a pretty smell that matches the rosemary shampoo—it’s earthy and fresh but not overpowering,” says Glamour tester Maura Benton. “After shampooing and applying a hair mask, I let the conditioner sit for about three minutes. It rinses out very nicely and doesn’t leave a film or buildup. My hair feels hydrated but not weighed down, and it’s very shiny. Using both the shampoo and conditioner has improved the health of my scalp, which will likely lead to fuller hair over time. I would certainly purchase this hair care product again.”

Pura D’Or Advanced Therapy Conditioner (16 fl. oz.)

Best for: All hair typesSize: 16 fl. oz.Key ingredients: Aloe vera, argan oil, olive oil, pumpkin seed extractFragrance: Tropical, coconut
- What we love: Lightweight; pleasant scent; noticeable difference in shedding
- What could improve: Thin texture may feel too slippery to some
This plant-based conditioner swaps out water for aloe vera, a more nutrient-rich base that delivers hydration and scalp-soothing benefits. The thin texture spreads easily, moisturizes well, and won’t weigh down fine strands. It also includes a blend of botanical oils—like argan, olive, and pumpkin seed—to support smoother, stronger hair. Our tester was impressed by how lightweight it felt, how much stronger her hair became postpartum, and the way it left her strands feeling healthier overall.
Our tester says: “I was pleasantly surprised by this conditioner!” says Glamour tester Shannon Browder, who tested the sister shampoo as well. “While it has a thin consistency—which made me skeptical at first—it spreads easily and doesn’t weigh my hair down. The scent is absolutely delightful, like a fresh, coconut mocktail that makes every wash feel a bit luxurious. I’ve noticed a significant reduction in hair thinning after a few weeks of use, which is a huge win postpartum. My hair feels stronger and healthier overall. Highly recommend for anyone looking for a lightweight yet effective conditioner.”

Your questions about conditioners for thinning hair, answered
Does conditioner for thinning hair actually work?
AccordionItemContainerButtonLargeChevron
Conditioner won’t regrow hair, but it can make a noticeable difference in how thinning hair looks and feels. “Their primary benefits are strengthening and hydrating the hair, improving texture, and adding volume, which can give the appearance of thicker, healthier hair,” says hair loss practitioner and certified trichologist Mandy Buechner. Most conditioners are applied to the lengths and ends—not the scalp—so they’re not typically designed to target hair loss at the root, says celebrity hairstylist Kat Thompson.
Still, certain formulas contain ingredients like biotin, caffeine, and amino acids that support scalp and hair health over time. “It all depends on the product formula,” says Dendy Engelman, MD, FACMS, FAAD, board-certified cosmetic dermatologist and Mohs surgeon at the Shafer Clinic in New York City. “Some can be very effective at supporting hair growth and retention, especially when used alongside targeted treatments and supplements. I suggest looking for products that have undergone clinical testing to back up their claims.”
What causes thinning hair?
AccordionItemContainerButtonLargeChevron
The most common cause is androgenetic alopecia, also known as male- or female-pattern hair loss. “This causes a widening of the part in women and a receding hairline or bald spot in men,” Brooke Jeffy, MD, a board-certified dermatologist who specializes in hair loss and skin care, previously told Glamour. This type of hair thinning is driven by a hormone called dihydrotestosterone (DHT), which gradually shrinks the hair follicle until it stops producing altogether.
How long can it take to see results?
AccordionItemContainerButtonLargeChevron
“If the issue is just fine and damaged hair, then you can start to see improvement in hair quality even after one wash,” says Kseniya Kobets, MD, a board-certified dermatologist and director of cosmetic dermatology at Montefiore Einstein Advanced Care. For concerns like shedding or thinning, it typically takes longer—about three to six months of consistent use—to notice fuller, stronger hair. “You’ll see a noticeable improvement in hair fullness from regularly using a high-quality conditioner,” adds Dr. Engelman.
What are the key ingredients in conditioners for thinning hair?
AccordionItemContainerButtonLargeChevron
Here are ingredients that frequently show up in conditioners for thinning hair:
- Biotin: Also known as B7, this is a B-vitamin that supports keratin production and can help improve hair strength, thickness, and elasticity. It’s one of the most widely used ingredients in both shampoos and conditioners for thinning hair.
- Keratin: A strengthening protein that reinforces the hair shaft, reduces breakage, and helps improve texture and manageability.
- Panthenol: Also known as provitamin B5, this humectant pulls in moisture and softens and smooths hair, making it appear fuller and healthier.
- Amino acids: These building blocks of protein can reinforce weakened strands, enhance flexibility, and reduce the likelihood of splitting—especially in fragile or chemically treated hair.
- Caffeine: This ingredient is believed to stimulate the follicles and support scalp circulation.
- Peptides: Short chains of amino acids that strengthen hair and support a balanced, well-hydrated scalp.
- Tea tree, peppermint, rosemary oils: Natural botanicals that may help improve scalp circulation, and create a fresher scalp environment.
- Hyaluronic acid: A hydrating molecule that can plump and moisturize strands, improving softness and reducing brittleness.
What should I consider when shopping for a conditioner for thinning hair?
AccordionItemContainerButtonLargeChevron
Take into account the source of your hair loss. A conditioner can strengthen and volumize hair, but it won’t address underlying issues like hormonal changes, stress, or nutrition. “It’s important to seek advice from a trichologist or dermatologist so the cause of the hair loss can be pinpointed,” says Carrie Prowant, certified trichologist and brand ambassador for hair-growth product Keranique.
Know your hair type. Fine, thinning strands need lightweight, non-greasy formulas that won’t weigh them down, while coarser or color-treated hair may benefit from richer hydration.
Look for targeted ingredients. Experts recommend biotin, keratin, panthenol, amino acids, and scalp-friendly actives like caffeine, rosemary, and tea tree oil to help cut down on split ends and breakage and boost volume. “It should have the right ingredients to help stimulate hair growth—otherwise it’s just a regular conditioner,” says Clyde Haygood, celebrity hairstylist and expert for hair-care brand PURA D’OR.
Avoid buildup. Skip silicones, sulfates, and synthetic fragrance if you have a sensitive scalp. “Fragrance-free and hypoallergenic options are best for anyone prone to irritation,” says Dr. Kobets.
Remember: Conditioner is not a cure. Conditioner works best as part of a broader routine—it won’t regrow hair on its own, but it can help protect what you have.
Can you use a hair-growth conditioner with any shampoo?
AccordionItemContainerButtonLargeChevron
You can, but for best results, Dr. Engelman recommends pairing products from the same system, as they’re often formulated to complement each other.“That said, you can use any products you want—just keep in mind that you may see slower, less significant results,” she says.
Are there certain conditioners that are better for men’s hair?
AccordionItemContainerButtonLargeChevron
Nope. “Conditioners may be branded and scented in a way that targets women and men differently, but the ingredients that promote hair growth and retention topically work equally well for women and men,” says Dr. Engelman.
