25 of the Best Shampoos for Thinning Hair for Your Fullest-Looking Locks Yet

• Active Ingredient: biotin, black cumin seed oil
• Best for: damaged and/or color-treated hair
• Promising Review: “[It's] my two year Pura D'Or anniversary. This shampoo helped regrow my postmenopausal (plus recent hysterectomy) thinning hair.”
• Cons: may leave hair feeling dry without conditioner

If you want results, Pura d'Or claims to have them: The company conducted a clinical study over eight weeks that reportedly proved its product resulted in less hair shedding. It relies on biotin as its main volumizing ingredient, but also includes black cumin seed oil, which may potentially aid in promoting hair growth and reducing hairfall. It's also jam-packed with more than 17 herbal ingredients that promise to nourish, cleanse and protects the scalp after every wash. To use it, lather up with it and leave it on your hair for a good two minutes before rinsing it out.

• Active Ingredient: salicylic acid
• Best For: fine hair
• Promising Review: “This is a great shampoo for fine thin hair. Hair feels and looks fuller, and I love the mint fragrance. Would recommend.”
• Cons: not cruelty-free

Dr. Gohara recommends this cleanser because she says it slows the progression of hair thinning by removing barriers to new growth (i.e., any buildup of oils, debris or toxins on the scalp) thanks to its salicylic acid exfoliation. "It's specifically designed to promote thicker, fuller-looking hair and a healthy scalp, and it addresses different levels of thinning across various hair types," she explains. For best results, you should massage it into your scalp for a minute or two, then rinse clean. Tip: Pair this shampoo with the scalp relief system kit ($46) for even more fullness and a soothed scalp.

• Active Ingredient: alpha keratin 60ku clinical protein
• Best for: straight, wavy, curly, and coily hair
• Promising Review: “Those wispy short hairs I’m always battling against frizz have actually had a chance to grow! Goodbye halo frizz and hello fuller looking and feeling hair!”
• Cons: may dry out hair with extended use

This one's core ingredients are not only formulated to nourish your hair and clear buildup from your scalp, the keratins are likely to make hair look fuller—and nurture it. "As new, fragile hair emerges, this shampoo ensures that it’s nurtured and cared for, so that it grows stronger and thicker," Vellozzi claims.

• Active Ingredient: biotin, zinc, gluco-omega
• Best for: thin hair
• Promising Review: “This shampoo (and conditioner) helps my hair look thicker and healthier.”
• Cons: some reviewers prefer the old formula

Given that thickening is in this cruelty-free shampoo's name, it stands to reason that you should expect voluminous results, and that's exactly what you'll get from it, according to reviewers. Its unique blend includes biotin, zinc and gluco-omega, all of which aim to get the anti-thinning job done. This formula also reportedly clears clogged follicles and removes buildup, according to the brand, so that your strands won't be weighed down.

• Active Ingredient: argan stem cells, grapeseed oil
• Best for: dull, weak, or thinning hair
• Promising Review: “I have age-thinning hair. I’m in shock! My hair not only feels thicker, but my husband asked me what I was doing differently.”
• Cons: some reviewers find it dries out their hair

This shampoo's secret lies in its organically-sourced argan oil, which has been shown to not only maintain moisture and improve scalp health, according to Healthline (both good things when attempting to stave off hair loss), it's full of vitamin E, which is a proven driver of hair growth. It also boasts hair-healthy grapeseed oil and nourishing aloe vera to give your locks a shiny finish. And as for that herbaceous scent? Shoppers say it's a refreshing treat for the senses, to say the least.

• Active Ingredient: Jamaican castor oil, rice protein, peppermint oil
• Best for: natural or damaged hair
• Promising Review: “I have course hair (Black). I use to always have breakage and parts of my hair with (bald spots) no matter all the tricks and trades. I usually shaved my head and called it a day. I started to grow my hair and using this and there is zero breakage!!”
• Cons: may be too heavy for fine hair, divisive smell

Curly and coily gals can rejoice knowing there's a shampoo for their thinning natural hair. While this brand doesn't claim its shampoo will grow hair quicker, the formula, which features castor oil, shine-boosting apple cider vinegar and strengthening shea butter, has omegas galore, which the company claims will reduce breakage. It's also full of rice protein, which has shown promise in studies for hair growth. Add peppermint oil to the mix, and your scalp will get a tingling sensation that leaves your hair feeling refreshed, shiny and soft. It may be best to use this one in moderation, however, as some have noted that the castor oil and protein is heavy on their scalp, leaving behind potentially damaging buildup. Shoppers are also divided on the vanilla-like scent, which some say is heaven-sent and others find off-putting.

• Active Ingredient: saw palmetto
• Best For: all hair types
• Promising Review: “Thinning spots have put out new growth. Pretty impressive results!”
• Cons: may take a few weeks to see effects

On the hunt for a gentle blend in a simple bottle? This anti-thinning formula contains saw palmetto, a plant-derived ingredient that is often used to help balance the sex hormone DHT, which is often linked to hair loss. In addition, this formula is loaded with soothing coconut oil, vitamin E and nourishing green tea. Better yet, Amazon reviewers say it's lightweight enough for everyday use.

• Active Ingredient: vitamin B7 biotin and collagen
• Best For: flat hair
• Promising Review: “Nothing I [used gave] my fine, limp, straight hair body without it looking damaged until I purchased this shampoo. Bar none…the absolute best!”
• Cons: not cruelty-free, full ingredients not listed

You can promote hair growth without having to break the bank. The sulfate-free shampoo, which rings in under $15, has more than 10,000 glowing reviews from Amazon shoppers. It uses both biotin (which, as we mentioned above, has shown promise for hair growth in supplemental form), and collagen. (Psst: Healthline says this protein helps with hair strength.)

• Active Ingredient: turmeric, ginseng and kakadu plum
• Best For: those with dry, itchy scalp conditions
• Promising Review: “I bought this product three weeks ago. My hair has been thinning and I had a very visible bare spot in my hair. I can say that this product works wonders and my hair is now thicker, fuller and has re-grown. I no longer have that bare spot after only three weeks of use!”
• Cons: doesn't lather well

This vegan and cruelty-free salon-grade option leads turmeric. Turmeric may not stimulate hair growth directly, but has shown promise in improving skin conditions, such as seborrheic dermatitis, which results in a scaly, itchy scalp and is closely associated with hair loss. There's also ginseng and kakadu plum to stimulate the scalp, per Paul Mitchell, and to increase the density of each strand, reducing breakage so your hair feels thicker as it grows.

• Active Ingredient: Gro’s proprietary Karmatin
• Best For: all hair types
• Promising Review: “Vegamour has given me back my confidence and my hair! Three months in and I'll keep going!”
• Cons: pricey

Anti-thinning shampoos can sometimes be paired with similarly formulated conditioners and other products to boost overall results. This comprehensive kit from Gro comes complete with a foam, a hair serum, a detoxifying scalp serum, a dry shampoo, biotin gummies and a conditioner that are all meant to aid its fully vegan shampoo. While it’s definitely a splurge, Gro touts its proprietary “Karmatin”—a vegan version of hair’s own vital protein, keratin—as its key hair-saving ingredient, while its wild-harvested marula oil, organic murumuru butter and ximenia oil aim to condition, hydrate and protect locks without clogging pores. According to studies conducted by the brand on 40 subjects over a four-month period, the formula increased the appearance of hair density by up to 52 percent. A separate study by the company of 20 subjects over the same time period also saw a 76 percent reduction in hair shedding.

• Active Ingredient: biotin, panthenol
• Best For: fine hair
• Promising Review: “Jason's shampoo simply makes it look fuller, as if I had more strands of hair.”
• Cons: some buyers find the bottle leaks during shipment

Sometimes, less is more. In the the case of Jason's Thick-to-Thin shampoo, for instance, the fewer the chemicals in your shampoo, the better. It employs a simple blend of biotin and panthenol (which comes from the B5 vitamin) to plump up tresses. It has no drying sulfates, and more than 700 5-star reviewers have vouched for this gentle, lightweight formula, which they say strengthens strands without weighing them down.

• Active Ingredient: salicylic acid, red ginseng
• Best For: fine, dry hair
• Promising Review: “I started using the Invati shampoo and within two to three washings my hair stopped shedding and I now barely lose any hair at all. Definitely far under the 100 hairs a day that's normal. I also see a ton of baby hairs growing all over my head.”
• Cons: not effective for some reviewers, can be too gentle on grease

Like the Dr. Gohara-recommended Nioxin, this plant-based formula has exfoliating, buildup-reducing salicylic acid in addition to red ginseng to combat thinning hair. It's cruelty- and sulfate-free, which means it may not be the best choice for greasy-haired girls, but the brand's signature scent (a divine blend of lavender, vanilla and rosemary) adds a nice touch. The company recommends using it for up to 12 weeks to see the best results.

• Active Ingredient: citric acid, wheat protein
• Best For: fine, limp hair
• Promising Review: “This is the only thickening product that ever really world for my baby-fine, limp hair.”
• Cons: some reviewers find it drying and prefer the old formula

The last thing anyone with thinning hair needs is a shampoo weighing down their already-limp strands. This cleanser is formulated to leave your scalp feeling refreshed thanks to the gentle citric acid exfoliant and your hair fuller courtesy of the thickening wheat protein moisturizers. It's also a great option for people with chemically-treated or bleached hair, as the gentle, sulfate-free formula protects your color and isn't stripping.

• Active Ingredient: caviar extract, citric acid
• Best For: straight, wavy, curly and coily
• Promising Review: “The search is finally over! This product actually does what it says it will. My hair looks amazing.”
• Cons: not cruelty-free, some reviewers find it doesn't lather well

True to its name, the core ingredient in this shampoo is caviar, but it also has Indian gooseberry. Both are rich in fatty acids, which can add (and help retain) moisture, shine and elasticity. The added red clover, meanwhile, is said to be chock-full of vitamins, and to have shown promise as a DHT-blocker. Together, buyers say they make for a lush lather that will leave you feeling like royalty every time wash day rolls around.

• Active Ingredient: keratin, pro-vitamin B5
• Best For: thin or flat hair
• Promising Review: “It truly adds volume and softness, but also was gentle on my hair color.”
• Cons: may irritate sensitive skin

With thinning comes a lack of shape to your hair. Rather than kiss your bounce goodbye, you might try this shampoo, which uses keratin and the aforementioned vitamin B5 to bring your broken-down strands back to life (zhuzhed-up tresses, here we come). It even has sunflower seed extract to protect color from fading. What's more, the hint of grapefruit and oatmeal will leave things smelling fresh-but-wholesome, and not overpowering, with softness as an added bonus.

• Active Ingredient: biotin, ginseng, maltodextrin
• Best For: oily scalps
• Promising Review: “Within three months my hair is thicker, longer and so much healthier and barely sheds.”
• Cons: some reviewers find it doesn't give their hair volume and leaves behind a residue

This extra-clarifying blend was formulated to thoroughly clean your oily scalp while simultaneously enhancing your thin strands with biotin and ginseng. It's also armed with maltodextrin, a natural sugar starch that can temporarily thicken and separate strands for what the company claims will be "added volume without stickiness." It should be noted that it is made without sulfates, however, which some extra-greasy scalps may prefer in order to truly eradicate residue.

• Active Ingredient: panthenol
• Best For: fine and medium straight and wavy hair
• Promising Review: “My hair is starting to get a little thin as I get older. To my surprise, this actually does work to make it feel fuller!”
• Cons: not fully color-safe, can be drying

Panthenol, which is the star of the show in this shampoo, was shown to reduce cell death and stalling in human hair cell follicles in a 2021 study. What's more, it stimulated an elongated anagen phase of hair growth. If you're scratching your head and going, "Um, translation?" Verywell Health explains that this is all just a very scientific way of saying that it worked to amp up the hair growth stage in which your strands are "actively generated." According to reviewers, just a dollop will turn your hair into a soft, hydrated masterpiece with ingredients like aloe vera, while also thickening your locks with every wash.

• Active Ingredient: biotin, saw palmetto
• Best For: graying hair
• Promising Review: “Since using this hair shampoo and conditioner, the hairline at my temples has filled in. I stopped coloring my hair and the natural colors blended with gray is so pretty.”
• Cons: bottle may leak during shipping

In a world full of hair loss products targeted towards men, it’s refreshing to know that this particular shampoo was created with women in mind. It offers a one-two punch of hair growth-inducing biotin and saw palmetto to balance out any excess DHT production that may naturally occur in some women, including those who may be going through menopause. Plus, it's safe to use on color-treated hair and is especially gentle on graying strands.

• Active Ingredient: biotin, zinc, tea tree oil
• Best For: all hair types
• Promising Review: “I love how it has helped my hair grow and look and feel so soft and full. I love it, worth every penny.”
• Cons: may not notice improvement right away

Don’t let the generic-looking bottle fool you: Honeydew’s shampoo has 700-plus rave reviews from Amazon shoppers and is reported to perform just as well (if not better than) its pricier competitors. With a fortifying formula that includes the ever-popular biotin, plus zinc, shine-inducing jojoba and coconut oils and scalp-clarifying tea tree oil, it will leave your hair feeling clean, sleek and amplified.

• Active Ingredient: biotin, quinoa
• Best For: all hair types
• Promising Review: “This has helped me with my hair loss, and in comparison with many other shampoos I’ve tried, it doesn’t cause my hair to feel oily, it feels clean and soft.”
• Cons: some reviewers state they prefer the old formula

There are few studies to prove quinoa's hair-growing powers, but experts believe it has plenty of healthful benefits for hair, and as Dr. Gohara explains, healthy hair (and scalps) tend to lead to fuller locks. It also has strengthening biotin in its corner. While other formulas boast the same, this one's main draw is that no animals or animal byproducts are used in its making. (It's entirely vegan.)

• Active Ingredient: peppermint oil, avocado
• Best For: dry, flaky hair
• Promising Review: “This shampoo controls my flaky scalp better than any I have ever used—including prescription shampoos.”
• Cons: cap may leak when traveling

This gentle formula, which includes peppermint oil and revitalizing avocado, is largely praised for its ability to cut down on dry, flaky scalps—which makes perfect sense, considering that peppermint is both antimicrobial and anti-inflammatory. As we've learned, this in turn leads to healthier locks overall. "[This shampoo] also allows for moisture and other treatments to penetrate, thereby keeping hair strong and healthy with lots of body," explains Philip B. It is recommended to apply the product to your scalp, massage it in with your fingers or a scalp massager and leave it on for three minutes before rinsing for best results.

• Active Ingredient: Australian wildberries
• Best For: those with excess oil
• Promising Review: “Leaves my scalp feeling very clean and not stripped of oils like other shampoos.”
• Cons: can be drying

As Dr. Gohara explained, healthy hair starts at the scalp, and if you have an overly oily scalp, chances are, yours has a pH balance that's out of whack. Nutrafol’s formula works to correct this, giving you a deep clean while balancing sebum levels, all without stripping your scalp of its essential oils. This physician-developed shampoo also works to nourish your existing locks, with antioxidant-rich Australian wildberries, strengthening vegan proteins, and prebiotics to keep your scalp’s microbiome healthy and thriving.

• Active Ingredient: biotin, rosemary oil, peppermint oil
• Best For: all hair types; also great on natural hair
• Promising Review: “It has improved my hair tremendously!! My hair looks healthier, it's more shiny, and I believe I am seeing some new hair growth.”
• Cons: may leak during shipping

This biotin-infused mint shampoo works threefold. First, it hits your scalp with its rosemary leaf oil, which experts have compared to 2.5 percent minoxidil. It's believed to promote circulation in the scalp, thus leading to cell turnover and growth. The peppermint oil, meanwhile, as mentioned above, is not only potentially effective for hair growth, but naturally antimicrobial and anti-inflammatory, helping to keep your scalp heath in check. Last but not least, there's biotin, which has been linked to hair growth. Per reviewers, the rich texture makes a regular shampooing feel like a luxurious treatment and will leave you with a shiny and soft rinse that doesn’t feel stripped.

• Active Ingredient: biotin, saw palmetto
• Best For: fine, thin hair
• Promising Review: “Best shampoo for my fine, thinning hair. I've seen the most growth ever since using this shampoo [and] conditioner.”
• Cons: may not add enough volume

Biotin is once again the star of the show in R+Co’s Dallas shampoo, aiming to up hair density and bring volume back to flat and lifeless hair. Better yet, it's got an added boost from DHT-balancing saw palmetto. Fans of this formula love how soft it makes their hair, thanks to bonus nourishing ingredients, like vitamin-packed berry extract and healthful coconut oil. It also reportedly helps keep hair clean for longer and gives some extra lift at the root. It’s color-safe and heat and UV protective to boot.

• Active Ingredient: caffeine
• Best For: straight, wavy, curly and coily hair
• Promising Review: “Really nice if you have fine hair and/or hair loss because it removes dirt and residue without stripping and gives beautiful body.”
• Cons: some reviewers find it to be drying

With a scent that blends the warmth of sandalwood and amber with the freshness of jasmine, cassis and bergamot, JVN’s Embody Daily shampoo will reportedly not only improve your hair’s volume, but make you feel like you’re at a 5-star spa. The clarifying shampoo uses caffeine, which was found in a 2007 study to block the sex hormone DHT in males that can damage hair follicles. It also stimulated hair shaft elongation (which led to longer, wider roots) and elongated the hair growth period. The same study found that caffeine promoted hair growth in females, too.
