About 50% of men and 25% of women will experience hair loss at some point in their lives. People are willing to pay high costs and risk side effects to find a solution. However, red light therapy for hair loss, as a non-invasive treatment, may be a superior alternative solution.
A 2014 study[1] found that red light therapy increased hair density and thickness, making it a safer alternative with no side effects. We have discovered the best red-light therapy for hair loss, which costs less than a dollar per day. Before that, I want you to know the key points of red-light therapy for hair loss in order to get the best results!

Research on red light therapy for hair loss
Red light therapy is a popular area of study because it has been shown to help in both medical and cosmetic ways. However, red light therapy does not treat everything, such as changing your hair loss genes. It uses low levels of light to stimulate cellular function and promote repair and healing.
For those interested in the potential benefits, keeping up with more news on their proper use is an essential habit. Below are experimental and clinical studies of red light therapy for hair loss that highlight its ability to stimulate hair follicles and result in thicker, healthier hair.
Some of the research history you should know
Pinar Avci collected and compiled studies on red light therapy for hair loss. His contribution is a review style research paper which is a valuable resource for our work.
Low-Level Laser (Light) Therapy (LLLT) for Treatment of Hair Loss[2]
- Research Methods
- The authors reviewed literature from 1960 to 2014, which included experiments such as hair growth tests in mice and humans under red light therapy. The literature also discussed clinical trials conducted on animals and humans, as well as studies on light with a variety of light sources, wavelengths, and powers.
- Conclusion
- Red light therapy appears to be safe and effective for treating hair loss in both men and women.
Action on hair follicles – regeneration & expansion
Androgenetic alopecia (AGA) is the cause of most hair loss, and follicular atrophy is one of the main symptoms.
“Dihydrotestosterone (DHT)” is the culprit that causes all of this to happen. Simply put, enzymes in the hair follicle convert testosterone to DHT, which acts on the hair follicle, causing it to gradually shrink.
Most clinical baldness is due to the gradual atrophy of the hair follicles, and you will experience a painful process of finer and softer hair that gradually decreases in diameter and density before going completely bald.
One of the reasons we found red light for hair loss is its ability to expand the hair follicle
- Research Methods
- A 24-week comparison study was done on 128 male AGA patients who used the cap device twice a week for 20 minutes each. The study group’s device contained a 660 nm red light and an 850 nm near-infrared light LED source, while the control group’s did not.
- Conclusion
- The study group showed a 35.4% increase in average hair volume and a significant increase in follicle size under magnified view
As mentioned above and in more studies, we have summarized the principle of red light therapy for hair loss. While it has a positive effect on most causes of hair loss, we recommend consulting a medical professional before using red light therapy to determine the best treatment option.
- Enhance cellular activity. Red light stimulates mitochondria to produce more adenosine triphosphate (ATP), a source of vitality
- Increases blood flow to the scalp. Providing more nutrients for hair follicle regeneration
- Decrease DHT levels to reduce hair follicle shrinkage and hair loss

Choose the best red light therapy for hair loss
The best light therapy for hair loss should be both gentle and effective, and LED red light fits the bill perfectly.
LED vs. Laser
Lasers have the advantage of high energy density, making them a suitable light source for use under professional medical supervision. You can usually find them in clinics or other professional physical therapy facilities with stricter regulations. For those of us who want to enjoy laser treatments at home, this means taking on higher power consumption and unknown safety risks.
While LED lights take longer to work compared to lasers, they have the advantage of being safe and supporting multiple wavelength treatments that are gentler and more effective. By getting a home red light therapy hair loss device, you can save yourself the expense of going to the clinic for multiple treatments.
Wavelengths suitable for hair loss
Research has shown that wavelengths of 660nm and 850nm are particularly effective in treating hair loss. The 660nm red light can promote cellular metabolic activity, which in turn enhances the growth and regeneration of hair follicle cells. The 850nm infrared light can improve blood circulation and promote the oxygen supply and nutrition of hair follicles, thus increasing hair growth and density.
Advanced at-home red light therapy devices now feature both wavelengths’ modes, combining the benefits of red and infrared light. With dual light modes, individuals can enjoy the advantages of professional-grade treatments in the comfort of their homes, minimizing the need for frequent clinic visits while optimizing convenience and results.
Cautions
When selecting devices, choose those that have FDA approval and low electromagnetic frequency. Confirming that these basic indicators are correct will help reduce the likelihood of exposure to hazards.
Instructions
There are some well known and compliant brands that sell red light therapy hair loss devices for home use, such as:
- iRestore Laser Hair Growth System is a no-frills, laser-based device, uses 21 lasers at 650 nm and 261 light-emitting diodes (LEDs). However, it requires a professional kit for use.
- HairMax Laser Hair Growth Comb is a more affordable laser device, but it requires a longer period of use to see results.
- Scienlodic Red Light Therapy Hat is a device that combines two of the most effective wavelengths for hair loss, with 120 LED light sources providing ample coverage.
As we mentioned earlier, when using red light therapy at home, it is best to use a safer and effective LED device. Therefore, we recommend Scienlodic Red Light Therapy Hair Growth Hat, it was developed based on rigorous red light therapy for hair loss research and uses two wavelengths of LED red light, the most effective for hair loss, as the solution.follow these guidelines to get better results
- Wash and dry your hair before use.
- Use in a relaxing environment, such as during a lunch break or while lying on the couch reading.
- Use 3-4 times per week for 10-20 minutes each time.
- Continue use for 4-6 weeks.
Summary
Red Light Therapy (RLT) is a safe and effective non-invasive hair loss treatment that combines different wavelengths to stimulate hair growth and improve the scalp environment.
LED is a more suitable option for at-home red light therapy hair loss, please use it after consulting a medical professional.
