Everyone experiences hair fallout (it's normal to shed anywhere from 50 to 100 strands per day), but if you regularly lose clumps of hair or notice patchiness on your scalp, it could be hair loss or thinning. "These signs may indicate miniaturization of the hair follicle, leading to permanent hair loss," explains board-certified dermatologist Suneel Chilukuri, MD. Though the underlying causes of hair loss include hormonal changes, genetics, and even traumatic events, healthy hair usually begins with a healthy scalp, so using a specially-formulatedshampoo for thinning hair can help improve scalp conditions that contribute to hair loss. 

Byrdie Researched & Approved

Our best overall pick is the Biolage Advanced Full Density Thickening Shampoo, a reparative formula that works to strengthen thinning strands while removing the follicle-clogging impurities that can prevent new growth. For a more affordable pick, consider the Viviscal Gorgeous Growth Densifying Shampoo, which our tester says left their hair looking and feeling thicker.

"The right growth shampoo can promote a healthier scalp to keep the hair in the anagen (growing) phase longer, which results in less hair fall," says Chilukuri. While there's no need to stress if you only see minor shedding in your hairbrush or shower drain, the best shampoo for thinning hair can help boost volume and thickness in most hair types. 

We conducted hours of research to determine the best shampoos for thinning hair. Our testers even put a few top-rated products to the test at home for several weeks, noting how well each formula addressed fallout and overall hair thickness, fullness, and strength. We combined these results with expert recommendations to compile our list.

Ahead, discover the best shampoos for thinning hair.

Best Overall

Biolage Advanced Full Density Thickening Shampoo

What We Like
  • Removes follicle-clogging impurities

  • Strengthens with biotin, zinc, and a gluco-omega blend

  • Fights frizz

What We Don't Like
  • Strong scent

This pick gets top honors for taking a two-pronged approach to thinning hair. First, it goes to town by gently removing follicle-clogging impurities that can impede new hair growth. Then it delivers a host of important nutrients—think biotin, zinc, and a gluco-omega blend—to strengthen the hair you have. So much so that, when used with the accompanying conditioner, it can reduce breakage by up to 95 percent. And when you’re already dealing with thinning, the less breakage, the better.

Byrdie contributor Leigh Weingus took this shampoo for a spin after experiencing postpartum hair loss, thinning, and general dullness. After using it, she notes that it not only left her hair shinier, fuller, and less frizzy, but it also noticeably reduced the amount of shedding she had been experiencing. “I really, really loved this shampoo and can’t think of one bad thing to say about it,” she says.

  • Gives body to fine, limp hair

  • Keeps hair cleaner, longer

What We Don't Like
  • Pricey

Whether your hair is naturally fine, you’re experiencing more shedding, or that dreaded combination of both, reach for this guy. The star of the show is a patented healthy hair molecule, which efficiently and effectively removes residue and build-up. Less gunk and grime equals thicker, fuller hair. Plus, this molecule also repels dirt and oil, so hair stays cleaner, longer. We’re not mad about that.

What We Like
  • Imparts instant volume

  • Exfoliates scalp and hair

  • Light rose scent

What We Don’t Like
  • Pricey

It admittedly takes a little bit of time to get used to this shampoo, given that it’s unlike any traditional liquid formula; you mix the paste with water, and it transforms into foam. But the volume-boosting results are well worth it. Rassoul clay and sugar crystals deep-clean both the scalp and strands, removing any trace of residue or oil that can weigh your hair down and leave it looking flat. Hot tip: It can sometimes make the lengths of your hair feel a bit dryer, so be sure to follow with a moisturizing conditioner.

  • A little goes a long way

What We Don't Like
  • May be slightly drying

When it comes to thinning hair, you want to go for a product that targets the scalp first, and this rosemary mint shampoo does just that.

What We Like
  • Contains anti-fungal ketoconazole

  • Fights chronic dandruff that causes shedding

  • Rich, thick lather

What We Don't Like
  • Bottle is small

It may not seem like the most obvious connection, but untreated, chronic dandruff may be linked to unwanted shedding. The active ingredient in this pick, ketoconazole, is an “anti-fungal and anti-yeast medication that has been shown, when taken systemically, to disrupt the action of DHT,” says board-certified dermatologist, Jeremy Fenton, MD, of Schweiger Dermatology Group in New York City. (DHT is a hormone that affects the hair follicle and can lead to thinning hair.)

“When using this shampoo, let it sit for two to three minutes on the scalp before rinsing to get the most benefit,” he suggests. Fewer flakes and thicker hair? Yes, please.

What We Like
  • Tea tree oil targets scalp inflammation and irritation

  • Fights dandruff and flakes

  • Amino acid complex strengthens the hair to prevent breakage

What We Don't Like
  • Strong scent

This shampoo gets right to the root of the issue. “Nioxin formulates their shampoos with antioxidants, peppermint oil, tea tree oil, and amino acids that are designed to strengthen the hair and prevent damage. It may not prevent hair loss, but it may help strengthen and improve the hair that you have,” says Fenton. Reach for this two to three times a week, more often if you have a particularly stressed-out scalp.

What We Like
  • Contains salicylic acid to control excess scalp oil

  • Keratin complex improves strength

  • Gentle enough to use daily

What We Don’t Like
  • Doesn’t lather very well

This is a true multitasking sudser that not only gently cleanses but also boosts thickness, strengthens hair, and helps to keep your scalp healthy. Keratin and wheat protein improve hair elasticity and strength, while salicylic acid helps balance any excess oil on the scalp and prevents the build-up of dead skin cells. FYI, it’s sulfate-free, so it may not lather as much as you’re used to.

  • Anti-fungal formula deters yeast growth

What We Don’t Like
  • Requires diligent use and time to see results

A multi-pronged, multistep approach is the most effective way to target hair loss, and this three-part system makes it easy to do just that. Start with the detoxifying shampoo, which boasts ingredients like saw palmetto, a natural DHT blocker. Follow it with the fortifying conditioner that hydrates and strengthens, and finish with the brand’s hero product, a leave-on activating serum that stimulates microcirculation, strengthens hair, balances oil production, and deters yeast growth.

True to its name, this formula helps to reduce breakage, so you can preserve more of the hair you do have. We also appreciate that it’s an exfoliating formula to help cleanse follicle-clogging residue and touts caffeine to help boost microcirculation on the scalp.

  • Naturally derived bergamot scent

What We Don’t Like
  • Requires months of regular use for best results

The star of the show here is a vegan silk protein that bonds instantly to hair—and stays put even post-rinsing, making strands look and feel noticeably thicker. And while it gives your hair that instant boost and lift, it also works over time to help make hair look fuller within three to four months. Plus, it contains a trio of wild-harvested, plant-based oils to help impart plenty of softness and smoothness. Those who color their hair will also appreciate that it’s free of sulfates and super gentle.

What We Like
  • Contains Alpha Keratin to address hair-thinning

  • Sodium hyaluronate and red algae strengthen hair

  • Works nicely for all hair textures

What We Don’t Like
  • Expensive

This celebrity-loved hair care brand is known for its proprietary ingredient, Alpha Keratin 60Ku, a combo of two different keratin proteins that repair damage and bolster elasticity to help reduce breakage and fallout. It’s the star of the show, but this shampoo also contains peptides that promote scalp health as well as sodium hyaluronate and red algae to seal moisture into the hair. We also appreciate that it suds up nicely, even though it’s sulfate-free. FYI, your hair will look and feel better after just one wash, but give it three to four months to see the full effects.

Final Verdict

Our best overall pick is Biolage Advanced Full Density Thickening Shampoo, which contains biotin, zinc, and a gluco-omega blend to strengthen hair while removing follicle-clogging impurities that can prevent new hair growth. If your hair thinning is due to chronic dandruff, consider Nizoral Anti-Dandruff Shampoo with the potent anti-fungal ketoconazole.

What to Look For in a Shampoo for Thinning Hair

Strengthening Ingredients

When you’re already dealing with thinning hair, you want to prevent breakage as much as possible. To do this, give your mane a strengthening boost with ingredients like biotin, keratin, and zinc. “Biotin improves the internal structure of the hair, which can help to prevent snapping and breaking,” says Federico. Using a shampoo that's formulated to make hair more resilient—like our best overall pick from Biolage—means you'll experience less breakage and fallout.  

Healthy Oils

If your hair is dried out, nourishing plant oils can help replenish moisture loss and prevent breakage. “Coconut oil promotes scalp health and helps prevent splitting and breakage,” explains Federico. These oils can be especially helpful if your hair is thinning out due to damage from chemical treatments or dyes. 

Sulfate-Free Formulas

Sulfates break down hair protein, strip hair of its natural oils, and can potentially cause even more breakage. Due to this, avoiding sulfates as much as possible will help prevent more breakage and help prevent dryness. 

FYI, your scalp routine matters too. “To repair thinning hair, you must take a very aggressive approach,” explains Federico. “First and foremost, I recommend doing everything you can to assure that your scalp is in its best condition. Hair grows through follicles on your scalp, and if those follicles are blocked or obstructed by dead skin cells, growth can slow or stop completely.”

FAQ
  • Do shampoos for thinning hair actually work?

    While results may vary depending on the product, the right shampoo can help slow and reverse hair loss. Look for a shampoo that gets to the root of the issue. If you have seasonal or hormonal hair loss, try a product like Davines Energizing Shampoo, which the brand’s hair care expert Chelsey Pickthorn explains works by adding shine and thickness to balance harsh environmental factors.

  • Is dry shampoo bad for thinning hair?

    Those dealing with thinning hair may want to avoid dry shampoo, so as not to cause further hair loss. Board-certified dermatologist Neil Sadick, MD, explains that excessive use of these products can lead to buildup, occlusion, and inflammation, all of which may lead to or escalate thinning hair. It’s better to use dry shampoo sparingly and instead wash your hair as often as it needs.
