At Neuronic, we often get asked whether near-infrared (NIR) light can help with hair growth. While our primary focus is on brain health and cognitive function, some users have reported unexpected benefits, including thicker, healthier hair. So, what does the science say about NIR light and hair regrowth? This blog explores the role of red and near-infrared light in hair health, the research behind it, and how it fits into broader treatment options.
The Best Wavelengths of Light for Hair Growth
Research suggests that the most effective wavelengths for stimulating hair growth fall within the red and near-infrared spectrum, typically between 630 nm and 850 nm:
- Red light (630–660 nm): Penetrates the skin and stimulates cellular activity, increasing blood circulation and encouraging hair follicle regeneration.
- Near-infrared light (810–850 nm): Reaches deeper layers of the scalp, reducing inflammation, enhancing mitochondrial function, and promoting hair follicle health.
Numerous studies suggest that low-level light therapy (LLLT) in this range can prolong the anagen (growth) phase of hair follicles and improve blood flow to the scalp. Devices such as laser caps, combs, and LED panels often use these wavelengths specifically for hair rejuvenation.
How Does Near-Infrared Light Promote Hair Growth?
Can the Neuradiant 1070 promote hair growth?
While the Neuradiant 1070 device has a peak wavelength of around 1070 nm, it still falls within the NIR range (700 nm -1400 nm). This longer wavelength, optimized for deeper tissue penetration, can still support and impact tissue closer to the surface, including hair follicle cells and surrounding tissue. Research suggests that near-infrared light can:
Boost Cellular Energy Production
Mitochondria in hair follicle cells absorb NIR light, leading to increased ATP production, the energy source for cellular repair and regeneration.
Improve Blood Circulation
Enhanced circulation delivers more oxygen and nutrients to the scalp, creating a healthier environment for hair follicles.
Reduce Inflammation
NIR light has been widely studied for its anti-inflammatory effects, which may counteract the chronic inflammation linked to hair loss conditions like androgenetic alopecia (AGA) and telogen effluvium (TE).
Stimulate Stem Cells and Growth Factors
NIR therapy may activate follicular stem cells and promote the release of growth factors that encourage hair regrowth.
As you can see, near-infrared has numerous benefits that extend far beyond hair growth and regrowth. While the near-infrared spectrum can help with hair growth, lower wavelengths have been shown to be more effective.
Scientific Evidence Supporting NIR Light for Hair Regrowth
Numerous studies have explored the effects of light therapy on hair loss, particularly in cases of androgenetic alopecia:
- A 2021 review by Pillai & Mysore published in the The Journal of Cutaneous and Aesthetic Surgery analyzed 15 relevant studies on LLLT and found statistically significant hair regrowth in both men and women. Some trials showed that LLLT was as effective as minoxidil, and combination therapy yielded even better results (Pillai & Mysore, 2021).
- A 2022 study by Ring published in the Clinics in Dermatology Journal reviewed the efficacy of various hair loss treatments, concluding that LLLT increased hair density significantly in randomized controlled trials. Notably, low-frequency LLLT appeared to be more effective than high-frequency applications (Ring, 2022).
- A 2020 review by Guo et. al. explored the mechanisms of LLLT for AGA, summarizing that red and near-infrared light can stimulate nitric oxide (NO) production, modulate reactive oxygen species (ROS), and activate signaling pathways that promote hair follicle regrowth (Guo et al., 2020).
- An Egyptian study (Amer, 2021) examined the effects of LLLT on hair growth over a 16-week period, reporting a statistically significant increase in hair count for patients with female pattern hair loss (FPHL)(Amer, 2021).
While further controlled studies are needed to establish optimal wavelengths and treatment protocols, existing research strongly supports the role of red and NIR light in hair regrowth.
Real-World Feedback From Neuronic Users on Unexpected Hair Growth
While our primary focus at Neuronic is on brain health and cognitive function, our users have reported unexpected benefits, including improved hair growth.
One user, Gerhardt, shared his experience:
"I started using the Neuradiant 1070 in January 2024, and I have seen major improvements since! I have always struggled with focusing and would occasionally use medication for ADHD. Ever since using the helmet, I have stopped taking medication as well as caffeine supplements. If I have to choose between using the helmet in the mornings or drinking a cup of coffee, I much prefer the helmet.
An unexpected bonus is that my hair started growing very quickly, and it stopped falling out. My family suffers from male pattern baldness, and I'm happy to say my hair has stopped thinning."
From a scientific perspective, Gerhardt’s experience aligns with existing research on NIR light’s ability to enhance cellular function, reduce inflammation, and improve circulation. His usage pattern involved continuous wave (CW) transcranial photobiomodulation (tPBM) for 10 minutes, followed by a 5-minute break, then 40 Hz at 75% intensity for 16 minutes. Initially, he used CW tPBM for nine months and found it worked better than Concerta and Bio-Plus for his ADD. Surprisingly, he also observed that his hair loss stopped. After adding 40 Hz stimulation, he reported further improvements in focus and energy.
NIR Light’s Role in Wound Healing and Inflammation
One of the most well-documented benefits of near-infrared light therapy is its ability to accelerate wound healing and reduce inflammation. This is particularly relevant for hair loss, as inflammation and micro-injuries to the scalp can contribute to follicular miniaturization and hair thinning.
A 2021 review by Glass Glass highlighted the increasing use of LED therapy in dermatology for treating inflammatory conditions, aging-related skin issues, and hair disorders. Additionally, case studies on lichen planopilaris (Randolph, 2020) demonstrated that LLLT could significantly reduce inflammation and support hair regrowth in affected patients.
By addressing inflammation at its source, NIR light creates a healthier scalp environment, potentially enhancing the effects of other hair growth treatments.
Should You Use NIR Light for Hair Growth?
If hair regrowth is your primary goal, we recommend exploring devices specifically designed for LLLT hair therapy within the 630–850 nm range. However, if you’re interested in cognitive benefits and overall cellular health, Neuronic’s 1070 nm NIR light technology may provide additional, unexpected perks—including potential improvements in hair quality.
Will everyone experience hair growth?
While many individuals experience noticeable hair growth using our 1070nm device, results can vary due to several factors. Individual responses to light therapy are influenced by genetics, hormonal factors, and the underlying cause of hair loss. For example, people with different scalp conditions, blood circulation levels, nutrient deficiencies, autoimmune conditions or sensitivities may respond differently. Additionally, consistency in treatment (using it daily versus weekly) and overall health, including age, nutrition, and lifestyle, can impact how effectively the light therapy stimulates hair regrowth. While some may see results more quickly or dramatically, others may need more time or adjustments to their routine to achieve noticeable benefits."
The Future of NIR Light Therapy for Hair Loss
While red light therapy (typically 630–660nm) has been widely studied for hair regrowth, near-infrared light (900–1100nm) is gaining attention for its deeper penetration and enhanced effects on cellular function. Future research will likely refine the optimal wavelengths and dosing strategies to maximize hair regrowth benefits.
For individuals exploring non-invasive hair loss solutions, NIR therapy presents an exciting avenue backed by growing scientific support. Whether used alone or in combination with other treatments, it offers a promising, drug-free approach to healthier, thicker hair.
Final Thoughts
While Neuronic devices are not marketed for hair regrowth, emerging research suggests that near-infrared light therapy plays a role in supporting scalp health, reducing inflammation, and promoting cellular regeneration. Whether used alone or in combination with other treatments, NIR therapy presents an exciting, non-invasive option for those looking to optimize their overall well-being.
