Top Men’s Hair Growth Supplements: 2026 Buying Guide

As the focus on longevity shifts from merely anti-aging to hair optimization, men’s perceptions about hair care are evolving significantly. A clear manifestation of this trend is the growing availability of supplements that promise to make hair appear thicker, shinier, and, in some cases, restore its natural color.

The most effective hair growth supplements for men are based on sound science rather than empty marketing claims. When integrated into a comprehensive hair retention approach, these supplements can address everything from lowering levels of dihydrotestosterone (DHT) — a hormone linked to male pattern baldness and prostate issues — to enhancing resilience against modern-day stressors.

“Hair ages just like skin,” notes Greg Ruggieri, a trichologist and owner of New York City’s Salon Ruggieri. He emphasizes that oxidative stress, a result of daily environmental exposure, can lead to significant damage over time. “Antioxidants play a critical role in slowing this deterioration at the hair follicles,” he explains, adding that they are also beneficial for skin health.

One notable newcomer in this field, Nutrafol’s Men 50+, incorporates the powerful antioxidant curcumin and a range of ingredients aimed at addressing the effects of aging on hair. As men age, they experience a decline in testosterone levels, reduced collagen production, accelerated cellular aging, and decreased nutrient absorption. These factors can compromise hair structure, impede growth, and diminish density. Notably, subscribing to these capsules grants access to the mental wellness app Headspace.

Aside from meditation, Nutrafol is not the only company making strides in this arena. Before diving into our top recommendations for effective hair growth supplements, here are some key ingredients to consider, as advised by Ruggieri, and their benefits for hair health.

Saw Palmetto: “This ingredient targets DHT at the hair follicle level,” Ruggieri explains. DHT is a major contributor to thinning hair in men, which is why it frequently appears in men’s supplements.

Pumpkin Seed Extract: Linked to DHT reduction and improved blood flow to the scalp, this ingredient is often underestimated. “It’s lesser-known compared to saw palmetto, but equally valuable,” Ruggieri notes.

Ashwagandha and Adaptogens: “Stress manifests in our hair, often leading to increased shedding,” Ruggieri says. Adaptogens help regulate our stress response, potentially minimizing stress-related hair loss, with ashwagandha being a standout adaptogen.

Silica and Keratin Amino Acids: Ruggieri highlights their importance in enhancing hair structure. “While they don’t necessarily encourage growth, they strengthen the hair, making it more resilient.”

Biotin and B-complex Vitamins: Essential for keratin production and cellular energy, these vitamins are vital for hair growth. Ruggieri states, “They’re crucial only in cases of deficiency; otherwise, they offer supportive benefits rather than miraculous solutions.”

Prebiotics and Probiotics: This group of ingredients supports gut health, improving the absorption of nutrients from other components in your supplement while also reducing gut inflammation. Ruggieri explains, “If your absorption is compromised or you experience inflammation, your hair is likely to show the signs.”

Antioxidants and Pigment Support: Ruggieri points out the growing understanding of how oxidative stress affects hair pigment. Ingredients like copper peptide, tyrosine, and various antioxidants are under investigation for their roles in preserving natural hair color.
