Low-Level Laser Therapy (LLLT)

Low-Level Laser Therapy (LLLT)

In this article, we explore the background of low-level laser therapy (LLLT), how it works, and how it can help restore hair growth.

Laser Light Stimulates Hair Growth

Multiple clinical and scientific studies have demonstrated the positive effects of low-level laser therapy. A wavelength of 650-680 nm, classified as red light, has been found to be particularly effective in stimulating hair growth. This red light is absorbed by the skin rather than sweat glands, allowing for precise stimulation of the skin’s energy system.

LLLT is effective against hair loss because it increases ATP (a crucial energy source for cells) at a molecular level in the cell nucleus. Additionally, red laser light enhances blood circulation, delivering more oxygen and nutrients to the hair follicles while preventing harmful DHT molecules from binding to hair roots.

Thanks to improved blood circulation and energy regulation, hair strands become healthier, grow faster, and appear thicker. Dormant hair follicles can be reactivated, leading to longer and fuller hair growth in areas where hair thinning has occurred.

Laser therapy also enhances the success of hair transplants by promoting faster and more effective healing. Furthermore, post-treatment hair quality tends to be superior compared to cases where no laser therapy is used.

The History of Low-Level Laser Therapy

Low-level laser therapy (LLLT) has been utilized in medical science since the 1970s. It leverages the effects of light with specific wavelengths on the skin. Unlike traditional lamps that emit a broad spectrum of wavelengths, lasers produce highly concentrated light at specific wavelengths. This targeted approach makes lasers highly efficient, converting all their energy into the desired wavelength.

LLLT has been studied for various applications, including treatments for rheumatism, eczema, and skin aging. Research also suggests that laser therapy accelerates wound healing and recovery from injuries.

Since the 1980s, several companies, such as Lexington International in Australia and Laser Hair Care in Sweden, have been developing LLLT for hair loss treatment. Initially, LLLT was only available in specialized clinics, where patients wore a cap connected to large machines. It was particularly popular before and after hair transplant procedures, as laser light was believed to accelerate the recovery of transplanted follicles. Even today, laser hair care caps are commonly used in hair clinics.

The First FDA-Approved Home Laser Device

Advancements in technology have led to smaller and more affordable laser diodes—the electronic components that generate laser light. As a result, Lexington developed the first home-use laser device: the HairMax LaserComb. This device, resembling a comb, features multiple low-level lasers on its underside.

To achieve official recognition as a hair growth device, Lexington conducted extensive independent research as early as 2005. The goal was to demonstrate the effectiveness of the device in treating male pattern baldness. In 2007, the U.S. Food and Drug Administration (FDA) acknowledged the research and approved the LaserComb as a hair growth device. This marked a historic milestone—LaserComb became the third officially approved hair growth treatment, following minoxidil and finasteride.

Advancements in Laser Therapy: Laser Helmets

In recent years, laser therapy has evolved rapidly. Following the success of the laser comb, laser therapy for hair loss has gained widespread popularity. Many individuals experiencing hair thinning sought a solution without unwanted side effects. However, one major drawback of the laser comb was its time-consuming nature—users had to comb their hair for 15 minutes daily, which often led to fatigue and frustration due to uneven light distribution across the scalp.

To address these challenges, more powerful and user-friendly devices were developed: laser helmets for home use. A laser helmet, equipped with clinical-strength lasers, evenly irradiates the entire scalp simultaneously, making the treatment completely hands-free.

While laser combs contain only nine lasers, modern laser helmets utilize 50 to 80 lasers, providing a significantly more powerful treatment. This makes laser helmets an effective and convenient solution for treating hair loss and improving hair density. The effectiveness of laser helmets has also been validated through FDA medical approval, which requires rigorous research demonstrating their impact on hair growth.

Benefits of a Laser Helmet

Beyond its proven effectiveness, a laser helmet is efficient, easy to use, and cost-effective in the long run. Below are some key advantages:

• Sustainable Treatment Method
  A laser helmet is a one-time investment that lasts for years, allowing unlimited treatments. It is effective as a standalone treatment for nearly all stages of hair loss.

• Ease of Use
  Using a laser helmet is one of the simplest hair loss treatments available. You simply place it on your head, press a button, and let it run automatically. Since the treatment relies solely on light, there is no need to apply any topical solutions, making it an excellent option for those who prefer a hassle-free approach.

• Hands-Free Convenience
  The treatment is entirely hands-free, allowing you to engage in other activities. With some models, like the SAT Laser Hair Treatment System, you can even move around freely during treatment. The convenience of a laser helmet makes it easy to incorporate two to three sessions per week into even the busiest schedules.

• No Side Effects
  Laser therapy is a completely safe treatment with no known side effects. It works by directing light onto the skin without causing harm. Additionally, the lasers produce minimal heat, ensuring a comfortable 20-minute session.

Laser Therapy for You

One of the most effective laser helmets for hair loss is the SAT Laser Hair Treatment System. This device has been scientifically tested in a double-blind study, where it was compared against a placebo (a device without laser light). The study confirmed that the helmet effectively combats hair loss in both men and women. As a result, the SAT Laser Hair Treatment System has been FDA-approved as a medical device for stimulating hair growth. It offers a simple and worry-free way to achieve thicker, fuller hair.

The SAT Laser Hair Treatment System laser helmet features 80 lasers emitting 678 nm light. Its wireless design provides complete freedom during treatment, allowing you to engage in other activities. A built-in battery supports four to five cordless sessions per charge. For optimal results, use the SAT Laser Hair Treatment System twice a week for 20 minutes per session.

Our Recommendation for Using a Laser Helmet

When Should You Use a Laser Helmet?

A laser helmet is suitable for both men and women at various stages of hair thinning and hair loss. However, research data is unavailable for cases of severe, advanced hair loss. Therefore, laser helmets are most effective for early to moderate hair loss.

Additionally, laser helmets serve as an excellent preventive treatment for hair loss. It is easier to maintain healthy hair follicles than to reactivate dormant ones. Regular use helps prevent follicular shrinkage, ensuring continuous nutrient supply and sustained hair growth.

Laser helmets are also recommended for individuals who struggle to maintain long-term treatment routines or prefer a low-maintenance hair loss solution.

Expected Results

Use the laser helmet two to three times per week for approximately 20 minutes. Follow the specific usage guidelines provided with your device.

Clinical research indicates that after three to four months, users experience thicker and more manageable hair, reduced shedding, and new hair growth. By 18 to 26 treatments, further hair loss is prevented. After 52 treatments, users typically notice significant hair regrowth.

Just like with exercise, consistency is key. Once you achieve your desired results, continue treatments every five days to maintain hair growth.

Should You Use Other Products Alongside a Laser Helmet?

Laser helmets are designed as standalone hair loss treatments and have been proven effective across various stages of hair loss. However, for advanced hair loss, combining a laser helmet with additional treatments is recommended.

Maintaining a healthy scalp is crucial for achieving the best results. Since hair loss is often linked to inflammation or fungal issues, using a high-quality shampoo (such as Neofollics, Regenepure DR, or Revita) can further enhance treatment success.

Can a Laser Helmet Be Used After a Hair Transplant?

Yes, laser therapy is beneficial both before and after a hair transplant. Hair transplants can cause damage to surrounding hair, but a laser helmet minimizes this effect and promotes the healing of transplanted follicles. It also helps reduce redness and discomfort while accelerating new hair growth.
