The 12 Best Shampoos for Thinning Hair for Men

Best Overall: Viviscal Man Full Force Fortifying Shampoo

Buy on Amazon Buy on Walmart

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 Splurge: Leonor Greyl Bain Volumateur Aux Algues

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 for Color-Treated Hair: Bosley MD BosDefense Color Safe Nourishing Shampoo

Best for Oily Hair: Briogeo Scalp Revival Charcoal + Biotin Dry Shampoo

Buy on Sephora Buy on Dermstore

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.

Buy on Nordstrom

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.
