Are Laser Hair Growth Caps Safe? Here's What Science Says

Hair loss impacts millions of men and women worldwide. While some medications can help restore hair loss, options are limited. This has led to an increase in individuals trialing alternative technology such as low-level laser therapy (LLLT). LLLT can be provided in a variety of ways, including caps or other devices. However, the safety of these devices has come into question. We will explore whether laser hair growth caps are safe and who may potentially benefit.

What Are Laser Hair Growth Caps?

About half of men 50 years of age or older are affected by pattern hair loss.  This condition can be stressful and negatively impact a person’s emotional health. There are FDA approved medications to treat pattern hair loss. However, these medications have several side effects. 

Low-level light therapy (LLLT) offers an alternative approach to hair loss. It works by using low levels of laser therapy to penetrate the scalp and stimulate hair growth. This method was first tested in mice in 1967 and was shown to be effective at regrowing hair shaved areas. Later in 2007, the FDA cleared the first LLLT device to treat pattern hair loss in men. Since then, many devices, particularly caps have been developed to treat hair loss.

Types of Laser Hair Growth Devices

There are several types of laser hair growth devices on the market. Common devices include caps, combs, and helmets. Each laser hair growth device has advantages and disadvantages.

•  Caps. These devices do not require manual use, and you can wear the device for a specified time. The CapillusPro laser cap is a commonly used device that requires only six minutes of use each day.
•  Helmets. Helmets can provide broad coverage of the scalp, but they tend to be bulky and more expensive compared to the other devices. One popular helmet device, the iRESTORE, uses LED light and laser technology to help regrow hair and is used three times per week for 25 minutes.
•  Combs. Combs are less expensive than caps, but will require manual use in order to be effective. However, you can target areas more specifically with a comb. HairMax® makes several brands of products including laser combs used three times per week for about 10 minutes each session. 

Are Laser Hair Growth Caps Effective?

Low-level light therapy has been shown to be effective in clinical trials. It can be a good potential option for those wanting to regrow hair that has been lost or is thinning. One study in men with androgenetic alopecia showed improvement in hair density after using LLLT for just 10 minutes a day. Another study conducted in men and women demonstrated significant hair growth after using LLLT three times a week for 26 weeks.

Expected Results and Timeframe

For the best results, it is important to use the laser hair growth device consistently and exactly as instructed. Individual results may vary and can range from two to six months depending on the device.  

Are Laser Hair Growth Caps Safe?

Many laser hair caps are cleared by the FDA for use. This means that the FDA has deemed them safe to use. It should be noted that FDA clearance does not guarantee that the product will be effective, however it does meet efficacy standards.  

Side Effects of Laser Hair Growth Caps

The side effects of laser hair growth caps are minimal and mostly consist of mild skin irritation, itching, or scalp tenderness. To reduce the likelihood of experiencing side effects, use the device as instructed by the manufacturer. Avoid using the product longer than the specified amount of time. 

Who Should Avoid Using Laser Caps?

Avoid these caps if you have photosensitivity or take medications that cause photosensitivity, or those taking medications that can cause photosensitivity should avoid using these devices. Prior to using a laser cap, talk with your healthcare provider. Discuss your current medical conditions to determine if a laser hair growth device is right for you. 

Pros of Using Laser Hair Growth Caps

Laser hair growth caps offer a few benefits compared to other hair growth strategies. A few of the benefits include:

•   Quicker results. You may begin to see results from using laser hair caps within two months. This is shorter compared to oral finasteride or minoxidil, which see results in three to four months.
•  Convenience. Laser caps are relatively easy to use and can be used at home for about 30 minutes a day.
• Accessibility. Laser hair caps can readily be purchased online or from a store. While you should consult with your provider before using a laser hair cap, a prescription is not required for purchase.
•  Non-invasive. Using a cap to receive LLLT is non-invasive and does not require downtime. You can continue with your daily activities right after using the device.

Potential Drawbacks and Limitations

There are also a few limitations to using caps over other therapies. The caps are relatively expensive compared to mediations, especially initially. Additionally, they may not be as effective for restoring extensive hair loss or baldness.  

How to Choose a Safe and Effective Laser Hair Growth Cap

When choosing a laser hair growth cap, there are a few things that you should consider. You first want to select a product that is FDA-cleared. This means that the product has been evaluated by the FDA for its safety and effectiveness. You also want to choose a device that is within the appropriate energy wavelength. The ranges from clinical trials include 620 to 678 nm. Finally, you want to select a device that fits your budget, but it should also fit comfortably and be easy to use. As it takes at least a couple of months to see results, you may also want to avoid purchasing products that promise more immediate results. 

Should You Try a Laser Hair Growth Cap?

Regardless of how you treat your hair loss, it is best to start early in the early stages of hair loss for optimal results. Laser hair caps do not have the ability to regrow a full head of hair, and advanced stages of hair loss may need more aggressive treatment.

 Laser caps are also used in conjunction with treatments such as topical minoxidil and oral finasteride. This combination can potentially enhance hair growth and results. Additionally, they can be used alone for individuals who cannot tolerate the side effects of those medications.     

Conclusion

LLLT is a non-invasive treatment option that can be used alone or in combination with other agents to help promote hair growth. Laser hair growth caps have minimal side effects and are generally considered safe to use with several caps being cleared by the FDA. As they may not be suitable for everyone, consult with your healthcare provider to determine if the caps can assist you on your hair growth journey.

FAQs

Can laser hair growth caps reverse complete baldness?

No. Laser hair growth caps and other laser hair growth devices, help to stimulate hair growth. However, they have not been shown to reverse complete baldness. It is best to start low-level laser therapy in the early stages of hair loss to try to slow the progression.

 How often should I use a laser cap for the best results?

This will vary depending on the type of cap that you purchase. Some caps require daily use while other caps can be used less often. Be sure to read and follow the instructions carefully on your chosen device. Consistent use is required for optimal results to be achieved.

Can I combine laser hair therapy with other treatments like Minoxidil?

Yes. Laser hair therapy can be used in combination with other treatments. In fact, using low-level laser therapy with topical minoxidil or oral finasteride may have a synergistic effect on hair growth. Consult with your provider before combining therapies.
