Introduction: Red Light Therapy for Androgenetic Alopecia
Androgenetic alopecia is a common condition of hair loss that has become increasingly prevalent in recent years. Although baldness is not a painful condition, it can impact your appearance and lower your confidence, as healthy hair is often regarded as a symbol of beauty. Everybody wants beautiful, healthy hair, but chemical shampoos and conditioners can strip away this beauty, potentially leading to hair loss in the long run. To combat this, numerous oils and treatments have been developed, although the majority of them do not meet their expectations. But a new treatment, red light therapy, presents a great solution for those who want to minimize hair loss. In this article, we will discuss how red light therapy for androgenetic alopecia works, stops continued hair loss, and induces hair regrowth.
Understanding Androgenetic Alopecia: Causes and Progression
Androgenetic alopecia is a progressive type of hair loss. Although baldness is not a painful process physically, it does have the potential to affect self-esteem severely. It is more commonly referred to as male or female pattern baldness and is an inherited condition characterized by progressive thinning and hair loss. It typically begins in men with a receding hairline and thinning of the crown, and in women, it presents as diffuse thinning over the scalp.
In this state, the hair follicles affected become smaller and produce thinner, shorter hairs. It usually begins in the late teens to early twenties and continues to develop over time. If the hair follicles become dormant, then baldness becomes more permanent unless it is treated early. In men, androgenetic alopecia can also be linked with other conditions like prostate cancer, enlarged prostate, and coronary heart disease. Moreover, stress is also a causative factor, and hair loss is occasionally viewed as a sign of some underlying medical conditions.
Challenges with Traditional Treatments for Hair Loss
Conventional therapies for androgenetic alopecia are medicated shampoos, conditioners, oils, topical preparations such as minoxidil, and oral drugs like finasteride. These must be used regularly, as shedding of hair can continue after treatment is discontinued. In most instances, these solutions do not work, and chemical-based shampoos readily available in the market tend to increase hair fall rather than prevent it.
Moreover, certain users might also develop side effects such as scalp irritation, hormonal imbalance, or reduced libido, making long-term usage problematic. Hair transplants, while successful for some, can be invasive and expensive, and are not suitable for everyone. Due to these difficulties, many people are now resorting to safer, non-invasive treatments such as red light therapy, which aids hair regrowth without the application of toxic chemicals or serious side effects.
How Red Light Therapy Supports Hair Growth in Androgenetic Alopecia
The Science Behind Red Light Therapy for Hair Follicle Stimulation
This is how red light therapy treats androgenetic alopecia. Red light therapy, also known as photobiomodulation and low-level laser therapy, utilizes specific wavelengths of near-infrared and red light that penetrate the scalp and naturally induce healing in the affected hair follicles. It increases the blood supply to the scalp, and as blood provides essential nutrients and oxygen, that is crucial to healthy hair development.
But why is this critical? Since enhanced blood flow brings more oxygen and nutrients to the follicle cells, allowing them to produce more energy and work optimally. Red light therapy enhances explicitly the function of mitochondria—the cellular powerhouses—that produce the energy necessary for cellular repair and growth. As a consequence, resting follicles are stimulated, and they start producing thicker, healthier hair. This renders red light therapy an efficient and non-surgical way of restoring dense, healthy hair.
Does Red Light Therapy Work for Androgenetic Alopecia? What Research Says
You may not research scientific studies prior to using conventional hair loss remedies, and in some cases, those remedies aren't scientifically supported. Red light therapy for androgenetic alopecia, though, is highly supported by science. Scientific studies indicate that red light therapy can induce hair growth, mitigate the effects of androgenetic alopecia, and enhance hair thickness and strength.
Clinical Studies on Red Light Therapy for Hair Regrowth
Study 1: Clinical Evaluation of 655 nm Low-Level Laser Therapy for Hair Regrowth in Men with Androgenetic Alopecia
Objective
This study aimed to evaluate the efficacy and safety of low-level laser therapy (LLLT) using 655 nm wavelength light for inducing hair growth in men with androgenetic alopecia.
Results
The men in the active group, who used the LLLT device, showed an average improvement of 35–39% in hair number after 16 weeks of treatment, whereas the placebo group remained minimally altered. The treatment group showed a rise from around 142 to 229 hairs in the treated region. However, the placebo group changed little. Crucially, there were no reported side effects or adverse events during the trial, and the treatment was well-tolerated. Statistical significance also appeared in the results, with evidence that red light therapy using 655 nm can stimulate the growth of hair.
Conclusion
LLLT at 655 nm is a safe, well-tolerated, and effective non-surgical treatment for enhancing hair growth in men with androgenetic alopecia.
Study 2: Effectiveness of FDA-Approved Low-Level Laser Therapy Devices for Treating Pattern Hair Loss: A Systematic Review and Meta-Analysis
Objective
The objective of this review was to assess the effectiveness of FDA-cleared low-level laser therapy (LLLT) devices, which employ wavelengths suitable for home use, in treating pattern hair loss (PHL).
Results
A meta-analysis of seven randomized controlled trials demonstrated that low-level laser therapy (LLLT) significantly improved hair density compared to sham devices (SMD: 1.27). Both male and female subjects benefited from the improvement in hair growth achieved using comb- and helmet-type low-level light therapy (LLLT) devices. Subgroup analysis demonstrated that LLLT with laser diodes alone had a more significant effect (SMD: 1.52) compared to combined energy sources (SMD: 0.85).
Conclusion
LLLT is effective in treating pattern hair loss; however, additional long-term studies are recommended, particularly for more severe cases, to evaluate its combined effects with conventional treatments and compare various devices.
Study 3: Efficacy and Safety of PBMT and PEMF for Androgenetic Alopecia Treatment
Objective
The purpose of this study was to assess the safety and effectiveness of Photobiomodulation Therapy (PBMT) using 660 nm and 808 nm wavelengths, together with Pulsed Electromagnetic Field Therapy (PEMF), in treating androgenetic alopecia (AGA).
Results
Following treatment for 24 weeks, the treatment group demonstrated a higher increase in hair density (139.37 ± 31.4/cm²) than the control group (119.78 ± 31.92/cm²), with a statistically significant difference (p < 0.05). The global assessment score was also greater in the treatment group (0.41 ± 0.62) than in the control group (0.07 ± 0.45). Mild erythema or irritation was noted, but no severe side effects.
Conclusion
The procedure involving the combination of PBMT with 660 nm and 808 nm wavelengths and PEMF is an effective and safe treatment for androgenetic alopecia.
Study 4: Photobiomodulation Therapy Using 660 nm Laser for Treating Androgenetic Alopecia
Objective
This study aimed to evaluate the impacts of photobiomodulation (PBM) treatment by a red low-level laser (660 nm wavelength) on androgenetic alopecia (AGA).
Results
The study demonstrated a significant increase in hair density after 5 weeks of PBM therapy (p = 0.0004). Nevertheless, after 10 weeks, no increase in hair density was noted since the 5-week point (p = 0.0285), and no difference was observed between the 5-week and 10-week assessments (p > 0.05).
Conclusion
PBM therapy effectively increases hair density in AGA patients within 5 weeks, but additional sessions do not result in further increased hair density. It was an effective and safe procedure with fewer sessions.
