While diet, lifestyle, and genetics affect hair loss more than just about anything else, the scalp is the first line of defense. Prescription hair treatments, such as minoxidil (generic for Rogaine) and finasteride (generic for Propecia) work wonders and are easier to get than ever. But you're like a lot of guys who are dealing with thinning strands, there's always room for more.
A good shampoo formulated for thinning hair will keep your scalp and hair in tip-top shape—and you'll begin to see serious results when it comes to strength, thickness, and overall health. You can't reverse thinning hair, but these formulas will build up what you have and prevent further loss. To help, we've rounded up our favorites for every budget and type of thinning hair out there.
Read on for the best thinning hair shampoos for men.
Best Overall: Viviscal Man Full Force Fortifying Shampoo
Viviscal hair growth supplements are some of the best in the business, so it should be no surprise that their corresponding shampoo is super effective as well. Using the potent combo of biotin, zinc, and keratin, this formula makes thinning hair look visibly fuller and thicker. For maximum results, we recommended adding the brand's drug-free hair supplement to your routine as well.
Best Budget: Every Man Jack 2-in-1 Thickening Shampoo + Conditioner
That tea tree tingle makes this shampoo feel refreshing on your scalp, while soy proteins help to plump up finicky follicles. Using 96 percent naturally-derived ingredients, this shampoo-conditioner duo is free of parabens, phthalates, dyes, and aluminum. Plus, it's all packaged in an eco-friendly bottle.
Best Drugstore: Old Spice Thickening System Shampoo for Men Infused with Biotin
The brand known for your dad's favorite aftershave has graduated into haircare-and it works. This biotin-infused shampoo is the best first step you can take towards better hair. Not does it do wonders with just one wash, but if you use their simple three-step system you'll have noticeably thicker-looking (and feeling) hair in two weeks.
Best Splurge: Leonor Greyl Bain Volumateur Aux Algues
This luxuriously lathering shampoo features volumizing and detangling benefits that give thinning hair a big boost with no further steps required. Loaded with seaweed proteins to fortify and condition, wheat proteins to strengthen and protect, and vitamin-rich plant extracts, this shampoo is worth every penny. Bonus: the super-concentrated formula goes a long way and doesn’t require a separate conditioner.
Best DHT Blocker: Hims The Stimulator The Shampoo+ for Hair Loss
This brand has become a major player in the wellness and self-care space, and this product is especially helpful when it comes to male pattern baldness and blocking DHT (a male hormone that contributes to hair loss). This reformulated formula highlights saw palmetto, a naturally-derived ingredient that is shown to boost testosterone and reduce inflammation—both key factors in maintaining a healthy head of hair.
Best for Instant Results: EVO Gluttony Volumising Shampoo
If you have fine, thin, or thinning hair, you’ll see instant results with this stellar shampoo. Vegan and cruelty-free, this color-friendly formula also lacks the sulfates that can fade gray hair. When paired with the conditioner, your hair will become undeniably more dense and full.
Best for Sensitive Scalps: Paul Mitchell Tea Tree Scalp Care Anti-Thinning Shampoo
Thinning hair can lead to sensitive scalps. This formula features the brand's proprietary Regeniplex blend—a mix of kakadu plum, pea peptides, clover flower, turmeric, and ginseng—which stimulates the scalp while providing fuller, thicker hair. The tea tree scent is offset with fresh notes of lemon, basil, and fir, as well as amber and patchouli. As with all Paul Mitchell products, this delightful douse of thickening lather is vegan and cruelty-free.
Best Anti-Dandruff: Head & Shoulders Full & Thick Dandruff 2-in-1 Shampoo & Conditioner
Thin hair and dandruff are not mutually exclusive. If your scalp goes beyond itchy to downright flakey, thinning hair can draw even more attention to the irritation. This iconic brand packs the two-in-one punch you need to eliminate flakes and illuminate locks.
Best for Color-Treated Hair: Bosley MD BosDefense Color Safe Nourishing Shampoo
With this shampoo, you don't have to pick between protecting color and thickening strands. This sulfate-free, nourishing formula removes styling build-up from the scalp surface, all while keeping color-treated hair healthy and moisturized.
Best for Oily Hair: Briogeo Scalp Revival Charcoal + Biotin Dry Shampoo
Excess oil can make thin hair look even thinner. When thin hair clumps together, more scalp peeks through, which in turn draws even more attention to your hair loss woes. Arguably one of the easiest, quickest, and fool-proof ways to thicken up oil strands is to opt for a dry shampoo between washings. This formula fools the eye immediately upon application, while helping to strengthen thinning hair over time.
Best for Dry Hair: Aveda Sap Moss Weightless Hydration Shampoo
Thin hair can be dry hair too. This hydrating shampoo features Iceland moss and larch tree sap to quench strands with serious moisture. This blend saturates dry hair without adding weight to already thin areas. The result? Happy and healthy hair that looks fuller.
Best for Damaged Hair: Kerastase Densifique Bain Densité Bodifying Shampoo
When your hair goes from just dry to full-on damaged, it’s time to get serious. Loaded with peptides, ceramides, and our favorite plumping molecule, hyaluronic acid, this shampoo works hard to ensure even the most damaged hair feels thick and healthy after a single wash. When thin hair needs even more added moisture, we recommend following up with the corresponding Kérastase Densifique replenishing masque.
