Yes, Hair Growth Devices Actually Work—and These Are the Best Ones Worth Buying (2025)

This FDA-cleared helmet-like device harnesses the power of red light therapy to not only hasten growth, but to prevent future hair loss, reverse pattern balding, and restrengthen the follicle.

According to , "Almost instantly, I noticed that my scalp seemed less greasy on my day to day. Within a couple of weeks, my hair felt stronger. And over a 4 month period, my hair grew to crazy lengths certainly the longest it has gotten in some time. But not just that. I saw areas near my temples fill out with new growth beyond baby hairs—something that has not happened in years."

One reviewer writes: "Easy to use and size fit in perfectly, it’s so nice that given timer and Bluetooth connected automatically, it’s comfortable to wear and it’s weight not heavy, the light feeling warm and the material feel so durable."

Suggested Use: 10 minutes daily for 16 weeks

Red Light Wavelength: 620-660 nanometers

From the brand behind the T&C-loved infrared sauna blanket and infrared mat, this red light hat comes with full coverage LEDs that increase blood flow in the scalp and reduce shedding and thinning, boost growth, and improve density.

T&C contributor April Long is a fan and says: "I love that it is so discreet and easy to use. It looks like a regular baseball cap, so I can wear it to walk the dogs or run to the store and no one would be able to detect what it is. I've been using it for the recommended 10 minutes a day for about a month and I notice significantly less shedding."

One reviewer says: "Before using I would have handfuls of hair come out in the shower but now I see so much less shedding. I see less white scalp than before and I see new growth."

Suggested Use: Every day for 10 minutes. Expect results in 1-2 months.

Red Light Wavelength: 650 nanometers

The most inconspicuous hair growth device on the market, this cap allows you to grow on the go. It comes equipped with hidden red light therapy technology, which "has been shown to be particularly effective in treating androgenetic alopecia, a type of hair loss caused by a combination of genetic and hormonal factors," says Dr. Ziering. Those dealing with menopause- and age-related hair loss can benefit from it, too.

One Amazon shopper says: "I never thought I could stop hair lose, but I was wrong. This cap has stopped my hair from shedding, and is growing back. And I don't have to spray or rub anything on my scalp. I hated the way my hair felt and doing that 2 times a day. It made my hair feel oily and stuff. But now my hair is soft and silky. Well worth the price! Just wish I bought it years ago."

Suggested Use: 6 minutes daily for 6 months

Red Light Wavelength: 650 nanometers

Not only does this brush use red LED to address hair loss, it also relies on blue LED to maximize growth and a gentle sonic vibration that massages the scalp for a soothing brushing experience. Not to mention, it's under $100.

One reviewer says: "I did not think it would work but im kind of desperate and cannot handle monoxodil it left my skin so itchy and I even had some weird hormonal fluctuations with my cycle so my doc advised me to get off. He told me to look into red LED so my search got me to this product, its cheap and has medical grade red 630nm. I used it in combination with a head massage with my fingers and i have seen hair fill out in places that were bald spots!"

Suggest use: Use on dry hair for 5-10 minutes

Red Light Wavelength: 620 nanometers

Blue Light Wavelength: 420 nanometers

What can't this device do? Not only is it powered with red light therapy, but it also has microcurrent technologies which help stimulate dormant follicles, therapeutic warmth for increasing blood flow, and massage capabilities that relieve tension. Adamiyatt is a fan.

One shopper says: "This product is amazing!! I just can’t get over how full my hair is getting. I have been using the product for3 months now and am truly amazed at the results!!"

Suggested use: 5 minutes a day

Red Light Wavelength: 660 nanometers

The iRestore is a hands-free gadget that treats your hair and allows you to multi-task at the same time. The FDA-cleared hair loss treatment uses red light therapy to promote a fuller and denser mane, and it comes with an accompanying remote with a timer display that lets you press pause or restart whenever needed. It's also worth noting that "red light therapy has no known side effects, making it a safer and more natural alternative," says Dr. Ziering.

One Amazon reviewer raves: "I am a 61-year-old woman, and my hair has been thinning for several years... I've been using the iRestore for almost two months... I'm happy to say that my hair is regrowing beautifully. I'm no longer self conscious about my hair style. I have lots of new baby hair coming in, and it's my natural dark color, not white like a lot of my hair is. I give most of the credit to the iRestore helmet; I've tried Rogaine for women in the past with little result, but this time around my hair is really responding."

Suggested Use: Every other day for 25 minutes. Expect results in 3-6 months

Red Light Wavelength: 655 nanometers

Powered by the same technology used in dermatologist offices and MedSpas, this FDA-approved device with red, blue, and near-infrared light therapy can not only help boost hair density and thickness, it can also be used on skin to reduce wrinkles and alleviate sore joints and muscles associated with arthritis or injuries.

One shopper says: "I have been using my Celluma Restore for about a month on my hair, face, knee and back and have noticed less pain in my MCL of my knee and relief in my back. Too early to tell for my hair but I have noticed that I do not lose as much hair in the shower or when I style which is a plus! My daughter commented that she sees a difference in my face, firmer and lifted around the mouth area. I am very happy with the ease of using and look forward to more improvements."

Suggested Use: Every other day for 16 weeks

Red Light Wavelength: 640 nanometers

Foreo recommends using it with your favorite topical for better results.

Suggested Use: Every day, for 1 - 3 minutes per treatment area

If you love the feeling of someone massaging your scalp, then you'll love the Breo Scalp3 even more because its bristles deliver a goosebump-inducing experience with three customizable modes and it has a vessel for oil application, as well as red light therapy.

One shopper says: "This feels so relaxing! It really feels like someone is massaging your head. I moved it around at different speeds on my head and found that when i went too slow it sometimes pulled at my hair (which is cut short). The red light therapy is a plus to help with hair growth and stimulation of your scalp/roots. I also love that i can add essential oils making it even more like a spa experience. Its lightweight, easy to maneuver, and clean. Convenient for travel."

Suggested Use: 10 minutes daily

According to Dr. Ziering, micro-needling can also deliver promising results for hair follicle health. If you're considering going down the that route, Bondi Boost's derma roller has 540 high strength medical grade stainless steel needles designed to be used across the scalp.

One reviewer says: "This is a must have in my products and tool from Bondi! I can already tell a difference in my thinner spots on my head. I just started incorporating this product into my weekly hair care routine! I use it after i shower in my wet hair and so far so good. I'm excited to continue using it to see how it promotes hair growth."

Suggested Use: Once a week on wet hair

According to Kerry Benjamin, an esthetician and founder of StackedSkincare, "high-frequency wands promote hair growth by stimulating blood circulation, delivering more oxygen and nutrients to the follicles for healthier, stronger hair. They also help reduce DHT, a hormone linked to hair loss, by preventing it from attaching to follicles." While it's most commonly used on skin to reduce acne and inflammation, this set comes with a comb attachment designed to treat hair loss.

One shopper says: "I have seen a notable difference in areas where my hair was thinning and I could see more scalp than hair. Wonderful device, easy to use and best part is it that it works."

Recommended Usage: Daily from 5 to 7 minutes; use with hair serum for best results

This hair brush features 12 medical-grade laser diodes that can be used to spot treat problematic areas or on the full scalp. According to clinical studies conducted by the brand, the device helps regrow hair with "an average hair count of 129 additional new hairs per sq. inch after six months." Plus, its compact size makes it travel friendly.

One Amazon reviewer writes: "My dermatologist recommended this product. He mentioned that I wouldn’t see hair growth right away, but the first signs it began working would be that my hair would stop falling out as much. He was right! I’ve only used it a few times, so far, and my hair falling has slowed substantially! I’m eager to see new hair growth now. One thing I recommend is that you use it every other day until you reach the maximum usage days to follow the three times a week as suggested in the directions."

Suggested Use: 3 times a week for 11 minutes a session.

When you want to achieve professional results at home, Dr. Ziering's cutting-edge hair growth device is a great bet. "The Ziering LaserCap stimulates inactive hair follicles using low-level laser therapy," Dr. Ziering explains. "It's a safe, all-natural, and painless hair regrowth treatment."

Suggested Use: 3 times a week for 30 minutes for the first 12 months

According to experts, there are many devices one can use to treat hair loss:

• Red light therapy: LED therapy provides a comfortable, non-invasive treatment free from side effects and offers a safe and convenient solution to address hair loss.
• LLLT (low-level light therapy): According to Dr. Ziering, "Cold lasers are clinically proven to increase hair density in patients with pattern hair loss over a 16-week timeframe using a wearable, helmet-type device."
• Micro-needling: As Dr. Ziering explains, "The process of creating wounds in the skin is thought to regenerate the health of the hair follicles. It’s thought that this can result in new hair growth, or perhaps, it may thicken thinning hair as seen in androgenic alopecia or male pattern baldness."
• High frequency wands: These devices help increase blood flow in the scalp, while also eliminating bacteria and reducing DHT, the hormone linked to hair loss.
