Laser Hair Growth Devices

A laser hair growth device is a new and valuable tool in the fight against hair loss or thinning hair.

Laser hair growth devices work by using low-level laser therapy that penetrates into the skin up to several centimeters, to promote hair growth which stimulates the blood circulation around your scalp and expands hair follicles.

The penetration depth might vary depending on the manufacturer or model of the laser hair growth device.

The lasers can stimulate both existing hairs as well as those in their dormant state which is why they stop hair loss.

Laser hair growth treatment is ideal for people who have experienced male pattern baldness, female pattern baldness, suffer from alopecia, or are experiencing thinning hair. 

We’ve rounded up the top laser hair growth devices on the market, to stimulate hair follicles, boost hair growth, and reverse thinning hair!

7 Best Laser Hair Growth Devices in 2024

Laser Hair Growth Devices Buying Guide

A laser hair growth device is a gadget designed to stimulate hair growth. It applies the laser technology that promotes circulation in the scalp and helps induce hair follicles into anagen, or active growth phases.

With so many laser hair growth devices on the market today, it can be difficult to find the right one for you and the hair challenges you are experiencing.

We’ve put together a comprehensive buying guide on which laser hair regrowth device is ideal for treating hair loss problems.

Laser Hair Growth Devices

As hair loss becomes more prevalent in society, so too do laser hair growth treatments. 

Laser hair growth devices are becoming increasingly popular among hair loss sufferers.

Laser treatment has the ability to treat many different forms of hair loss, and laser hair growth devices are available for both at-home use and professional treatment.

Laser hair regeneration devices stimulate healthy regrowth of hair no matter what type of hair loss a person is suffering from; either temporary or permanent.

Lasers (Light Amplification by Stimulated Emission of Radiation) work like ordinary light, but at a higher intensity.

Laser hair growth devices work by emitting laser light to stimulate cells under the skin (called dermal papilla cells) and activate enzymes that promote hair growth.

Some studies have shown that low-level lasers can increase blood flow in the scalp, which could help deliver nutrients—like hormones and proteins—that promote hair growth.

Hair Loss

In men, causes of baldness can be from male pattern baldness or from causes related to scarring from injury or burns, certain medications, tumors of the scalp, or an autoimmune disease called alopecia areata. 

This is where a person's immune system attacks their body's tissue, causing hair loss in a circular or patchy pattern.

In women causes for hair loss can be associated with menopause, pregnancy, too much stress on the body causing hormonal changes in your body causing a woman's hair to go through a spasmodic stage.

Other causes of hair loss are nutritional deficiencies, anemia, thyroid disease, lupus, and polycystic ovarian syndrome.

Using laser technology to help stimulate hair growth has become very popular throughout the world for both men and women. 

Therapeutic Laser Light Therapy

The lasers work by producing red and infrared light at low levels which causes the cellular activity to increase, stimulating hair follicles, and inducing hair growth. 

Therapeutic laser light therapy also causes the blood flow in the scalp to increase which helps encourage new hair growth and treat hair loss. 

Low levels of Infrared light penetrate the skin's surface to invigorate cells in its basal layer, which stimulates stem cells of dormant hair follicles.

As well as this, infrared light revitalizes blood flow which delivers oxygen and nutrients to stimulate hair growth.

The lasers can revive both existing hairs as well as those in their dormant state which is why they stop hair loss.

Benefits of Laser Hair Growth Treatment

Hair loss sufferers who have been unsuccessful with hair regrowth by utilizing shampoos and conditioners, or hair vitamins, have an alternative option for hair restoration with hair regrowth lasers. 

They are safe and painless as they don’t emit any heat or light on the skin.

They encourage hair growth and produce results without material side effects, or potential health risks.

Laser hair growth devices stimulate hair regeneration, to combat a receding hairline and make the hair thicker. They can treat hair loss without the need for manual hair transplants which expose patients to dangerous side effects.

Hair growth devices can also improve the hair follicle, hair intensity, and hair density, which makes hair regrowth lasers the perfect option for hair restoration without surgery.

Laser hair regrowth systems have been proven to treat male pattern baldness, female pattern baldness, treat sufferers of alopecia, those experiencing hair thinning, with a more natural hair growth system. 

Each person suffering from hair loss issues may have different needs when it comes to laser hair growth devices.

Positive results are determined by consistent use, the person’s age, and how quickly their hair grows.

Ensure you use the laser hair growth device as per the guidance of the manufacturer, combined with good nutrition, an active lifestyle, and the right scalp routine. 

Features of Best Laser Hair Growth Devices

Types of Lasers

Lasers can help increase blood supply and cellular metabolism, increase hair follicle size and strength, promote hair regeneration, as well as cause a reduction in DHT levels which can contribute to hair loss.

Different types of lasers can be used in a laser hair growth system. When selecting a laser hair regrowth device, some questions are what is your skin color? Hair color? Do you have any medical conditions?

Diode Lasers

The diode laser has wavelengths between 800nm-880nm. Overall, diode lasers tend to work best on vellus hair. They are good for spot treating specific areas of thinning.

However, one of the downfalls of diode lasers is that they are unable to produce multiple wavelengths which limit their ability to target melanin in the surrounding tissue.

Diode lasers are usually less powerful, more affordable, and can be used on all skin colors. 

Nd Yag Lasers

Nd Yag (neodymium-doped yttrium aluminum garnet) lasers are often considered the "gold standard" when it comes to hair restoration devices.

Nd Yag has wavelengths between 1064nm-1070nm. It is used to treat the early stages of hair loss and thinning.

Nd Yag emits infrared light to help penetrate the surface layers of skin, helping with cellular metabolism and blood supply to encourage new growth.

They are very effective for all skin types, are less expensive than Alexandrite lasers, and can be used on multiple wavelengths. 

Nd Yag lasers work well with all different types of hair and the whole head. 

Alexandrite Lasers

The Alexandrite laser has wavelengths between755nm-780nm. Alexandrite lasers are more powerful, have a wider range of wavelengths, but can only be used on darker skin types.

Alexandrite lasers tend to work best on coarse, thick dark hairs. Home-use devices are small, inexpensive, and easy to use with minimal side effects.

They are also usually the most expensive laser hair growth device out there.

Low-Level Laser Therapy (LLLT)

LLLT laser has wavelengths between 640nm-680nm. LLLT is one of the most basic and least expensive forms of laser hair growth treatment where lasers are used for their ability to vibrate, which can help with hair growth just as well as the other lasers.

Low-level laser therapy uses LED light that helps stimulate blood flow to nourish existing hair follicles, making them stronger and healthier.

Low-level laser therapy works best for those who are looking for a device that is not only affordable but effective as well.

It can be used in conjunction with other treatments and is an easy and safe way to help boost the effects of existing hair loss treatments or stop future hair loss from occurring.

Types of Laser Hair Growth Devices

Laser Cap

A laser hair growth cap is a hat, designed like a baseball cap, with embedded lasers that emit light of different wavelengths targeting specific areas of the scalp.

Typically used for 5 to 30-minute sessions, at least 2-3 times a week. May not be for individuals who are not fans of laser caps.

Laser Hair Growth Helmet

A laser hair growth helmet is a little bulkier and more apparent than caps, but they tend to have greater power, provide full scalp coverage, and are typically better designed to target hair follicles for the entire head.

Laser Comb

A laser comb is a handheld gadget that allows you to directly massage the areas of your scalp where your hair is thinning to stimulate new hair growth for thicker hair.

Laser combs bristles can stimulate your skin and promote blood flow circulation, allowing you to brush thick, healthy hair out of the way for direct, and efficient treating of hereditary hair loss and regrow hair.

Laser Headband

Laser headbands can provide full scalp coverage for the entire scalp, and they are more adaptable and inconspicuous than helmets as a hair growth system.

Laser bands for the head usually contain fewer laser diodes than helmets but more laser diodes than in laser combs.

Laser headbands allow you to target just the problem regions on your head where your hair is thinning, or you may use them to promote hair growth throughout your entire scalp.


If you're buying a helmet or cap-style laser hair growth system, be sure to think about the size of your head, from a circumference point of view.

If the helmet or laser cap cannot be adjusted, make sure you select the correct size for your head, as you don’t want the helmet/laser cap laser devices to be too tight or too loose.

Severity of Hair Loss

Are you experiencing thinning or balding on your whole head? Or are you dealing with tiny patches in specific areas? Such as a receding hairline, bald patch on the top of your head?

If you are experiencing hair loss/thinning in patches and specific areas, you might be better off with a laser headband or laser comb that allows you to target specific patches for “spot treatments" in certain areas. 

For more widespread hair loss, consider purchasing the best laser cap or helmet-style laser device that can treat your entire head with comprehensive scalp coverage.

Cycle Time

The frequency of treatment, usually in the form of laser hair reduction treatments, is another factor to consider. Some laser hair regrowth devices recommend 20-30 minute sessions 2-3 times per week, while others advise 4-10 minute sessions twice daily. 

If you find it difficult to fit in 20-30 minutes of therapy every day owing to your hectic schedule, a device with a shorter daily cycle might be a better option.

FDA Clearance

FDA-approved technologies have been subjected to extensive testing for safety (if not efficacy), indicating that they comply with specific quality control and operational criteria.


If you expect to go on a trip, consider purchasing a laser hair growth device that you can carry with you. You don’t want to interrupt your laser hair growth system treatment.

The laser hair growth helmet is best for at-home usage, but it may be too big to transport.

The laser headband and laser comb-style devices are more compact and a good option, however depending on whether they are a corded or wireless devices may impact their convenience. The choice would be the best laser cap-style device.


Hair regrowth devices are not cheap, but what is the price of your hair worth to you? When considering what device to purchase it is important to think about what type of lasers are being used.

The pricier models tend to use more than one kind of laser technology which is what makes them more effective than the cheaper alternatives.

The price of laser hair growth devices ranges from $499 to $3,000.

Laser Hair Growth Devices FAQ

What are the reasons for hair loss?

The main reasons for hair loss are genetics, medical conditions, stress, diet choices, and age.

One primary reason for hair loss is genetics. If your parents have or had early onset hair loss then you might experience hereditary hair loss too. 

A common reason for going bald however is male pattern baldness. This condition is caused by a genetic predisposition and typically begins around the age of 30 or 40 years old.

Men with male pattern baldness will usually see a receding hairline and possibly hair thinning across the crown of the head. This type of hair loss is also known as alopecia androgenetic or alopecia neoplasia.

The second reason for hair loss is medical conditions, such as thyroid disease and an underactive or overactive gland in the reproductive tract called the ovary (although this isn't directly related to male pattern baldness).

Hair can also fall out if you're extremely stressed or have an eating disorder. Age is also a reason for hair loss.

If you're in your mid-to-late thirties and see significant hair loss, it's possible that it's caused by something more serious than aging (i.e.medical conditions).

Which laser hair growth device is the best?

Which laser hair growth device is the best for you depends on the type of hair loss and the extent of hair loss you have. Whether you require a hair laser device to encourage hair growth for spot treatment or entire scalp coverage. 

Furthermore, it depends on your skin color, hair color, whether you have any medical conditions, and last but not least, from a comfort perspective what type of laser devices do you prefer? A laser comb, or laser headband or laser cap, or a laser helmet.

Do laser hair devices work?

Hair loss is an unfortunate and common condition that affects millions of people around the world. It can be extremely difficult to cope with and can lead to low self-esteem and depression if left untreated.

The good news is that there are ways to prevent it from happening or treat it once it does. One of the most effective treatments is a laser hair growth device.

The key ingredients in any laser hair growth product are red-light lasers and infrared light lasers.

They are designed to stimulate hair follicles in the scalp, which will encourage new hair growth and encourages hair growth of existing hairs.

This treatment is most effective for people who have experienced hereditary thinning of the crown or frontal areas of their scalp.

According to studies, laser hair growth devices stimulate about 40 percent more active follicles than other forms of treatment like Minoxidil or medication. 

Does low-level light therapy hurt?

Laser hair growth devices use a combination of red and infrared beams to both promote the growth of existing strands, as well as strengthen new ones.

Unlike laser hair removal, no pain is experienced when using a laser hair growth device on any area of your body.

The low-level lasers used in these devices produce enough heat to stimulate blood flow but not enough to damage tissue. The low-level lasers are often called cold lasers, as they don’t generate heat.

There are some side effects of using laser hair growth devices like redness of the skin or itching, in the event you suffer from sensitive skin. It's important for users to understand these so they can use the device correctly.
