The 6 Best Hair Growth Devices for Men in 2025, According to Dermatologists

Torn between an LLLT and LED device? This nifty helmet makes the tough decision moot by including both. It combines laser diodes and LEDs, aiming to balance the gentleness of LEDs with the intensity of lasers (the only option on this list that offers both). Plus, Dr. Witkowski supports it, noting the FDA clearance and manageable treatment times (25 minutes, three times a week).

He adds that the mixed diodes (lasers and LEDs) make it a powerful resource in treating alopecia symptoms, like receding hairline, balding, and thinning. The tool is easy to use, simply plop it on and go, while being hands-free to allow you to perform other tasks during the nearly half hour you’ll be wearing it.

At just under $500, it’s more budget-friendly than other LLLT devices, like the popular Capillus Cap, which is nearly twice that. That being said, it’s far bulkier than the Capillus Cap and other LLLT devices, which makes it difficult for travel. But if you’re planning to only do treatments at home, you won’t find a better value or combination of effective treatments.

When it comes to light-based devices, the biggest thing to keep in mind is that the light has to reach your scalp in order to give its full benefits. If you have heavy thinning or bald spots, caps and helmets should be fine, but this comb is great if you have decent hair density because the laser is aiming directly at the scalp.

Use this comb like you would a regular hair brush, and the bristles help part your hair to ensure the light from the 12 laser diodes (LLLT) penetrates and reaches your scalp. “Clinical studies have shown an average hair count increase of 129 additional new hairs per square inch after six months of consistent use,” says Dr. Witkowski. However, Dr. Jeffy does note that using a laser comb takes more effort than putting a helmet-based treatment on.

Intimidated by the bulky, sci-fi-looking helmets? This tool simply resembles your favorite simple baseball cap. Men’s Health writer Bob Gearing used the HigherDose Red Light Therapy Hat daily for a year and stands by its effectiveness, saying it works better than Rogaine without the side effects—no irritation or redness.

It’s simple to use: just wear it like a regular hat for 10 minutes a day, as 650 nm red light penetrates the scalp to support hair growth. While the brand suggests full results in 16 months, noticeable improvements often show by month six.

Unlike the similar Capillus Pro Laser Therapy Cap, which emits visible light from the sides, this hat is discreet and stylish—easily worn in public without drawing attention, making it effortlessly blend into any daily routine. Not to mention, HigherDose’s cap is nearly a third of the price.

Dr. Witkowski says this massaging serum applicator—also known as a liquid comb—is designed for daily scalp care and suits all hair types and textures. Rather than solely helping promote hair growth on its own, this scalp massager evenly distributes a hair growth serum across the scalp and hair, delivering key nutrients directly to follicles while stimulating the scalp through gentle massage.

The tool works with or without liquid products, and when paired with the brand’s own topical treatment, which is free of skin-irritating parabens or sulfates, it enhances the results. Regular use helps boost blood circulation to the scalp, a factor that may support healthier hair growth over time.

This microderma roller is simple to use, and costs about the same as a latte in New York City (though this is another issue entirely). Its titanium needles glide across the scalp to increase blood flow to the scalp, encouraging hair growth, while helping to boost any serum absorption. Plus, the titanium needles are designed to resist bending and rust, ensuring long-lasting performance. The frosted silicone grip feels comfortable and secure in the hand, making this one of the most seamless user experiences on this list.

That being said, Dr. Witkowski notes that microneedling devices like this are most effective when used in tandem with serums or other topical treatments, like minoxidil, corticosteroids, or biotin, and won’t be too effective on their own. Still, at $10, there’s barely a risk in trying.
