If you’ve noticed your hair looking thinner or your scalp showing more, you’re not alone. By age 50, about 50% of women experience noticeable hair loss. But what if there was a simple, non-invasive way to stimulate hair growth right at home? If you’re looking to improve hair thickness and growth, red light therapy may help.
How Does Red Light Therapy Promote Hair Growth?
Red light therapy delivers gentle, low-level wavelengths of light to the scalp. The light interacts with cells in the hair follicles and cutaneous tissues, providing both anti-inflammatory and growth-boosting benefits:
- Improves blood flow: Red light exposure dilates blood vessels and enhances microcirculation around the follicles. Better blood flow brings more oxygen and nutrients to hair roots, supporting growth.
- Activates anabolism: The light boosts adenosine triphosphate (ATP) and keratin production in hair matrix cells. This energizes and strengthens the growing phase.
- Reduces oxidative stress: Red light generates reactive oxygen species (ROS) which trigger defense and repair processes in the cells. This helps protect follicles from damage.
- Decreases inflammation: Red light exposure limits inflammatory cytokines and increases growth factors like IGF-1. This reduces hair follicle inflammation and miniaturization.
- Modulates hormones: Red light may help balance hormones like cortisol and testosterone which impact hair growth cycles.
- Stimulates anagen: Through these combined mechanisms, red light pushes more follicles into the anagen-growing phase while extending this phase.
In summary, red light therapy energizes hair follicles, reduces scalp inflammation, improves blood flow, and enhances factors that stimulate hair growth.
Benefits of Red Light Therapy Over Traditional Hair Growth Products
There are many shampoos, conditioners, supplements and topical products marketed to prevent hair loss and stimulate growth. However, some advantages of using red light therapy include:
- Red light therapy is a safe, non-invasive treatment that works with the body’s natural processes. There are no chemicals or potential side effects.
- Devices allow light to reach the entire scalp for overall stimulation. Topical products only treat localized areas.
- Red light improves scalp health and blood flow which contributes to stronger, thicker hair growth.
Who Can Benefit from Red Light Therapy for Hair Growth?
Red light therapy may help with:
- Androgenic alopecia: Also called male or female pattern baldness, this common form of hair loss is driven by hormones and genetics. Red light could help counteract the miniaturization and shortened anagen phase.
- Alopecia areata: This autoimmune disorder causes patchy hair loss. Red light reduces inflammation and modulates immune factors.
- Telogen effluvium: A shedding condition often triggered by stress, medication, or postpartum changes. Red light helps push follicles from telogen back into anagen.
- Hair thinning from medication: Drugs like chemotherapy often damage follicles, while others like antidepressants impact hormones. Red light may help counteract these effects.
- Stress-related shedding: By reducing oxidative stress and inflammation, red light can minimize stress-induced shedding.
Because red light supports the body’s natural healing processes, it is safe to use long-term for continued hair growth improvement.
Is Red Light Therapy Proven to Grow Hair?
Multiple clinical studies suggest that red light therapy promotes significant hair growth and slows hair loss:
- A 2014 trial on 22 patients found that red light comb treatment 3x a week for 24 weeks increased hair density by 31% on average. It also reduced hair shedding by 28%.
- In 2017, researchers treated 41 patients (18 men, 23 women) with alopecia areata for 12 weeks using red light caps. Hair regrowth occurred in over 75% of cases, with an average increase of 43 new hairs per cm2.
- A 2019 study on 28 men with androgenic alopecia found that using a red light LED device for 15 minutes daily led to a 37% average increase in hair density after 16 weeks.
- A 2020 meta-analysis looking at 11 studies found red light therapy increased hair count by an average of 17.7 hairs/cm2 and reduced hair loss by 37.2%.
While individual results can vary, these studies demonstrate red light’s ability to improve hair density, activate growth, and prevent excessive shedding. Effects tend to accumulate over 3-6 months with consistent use.
However, red light therapy shows the best results when treating mild to moderate hair loss. It works well alongside other treatments like minoxidil, microneedling, or oral supplements for optimal regrowth.
Are There Any Side Effects of Red Light Therapy for Hair?
Red light therapy is very safe and non-invasive. There are generally no side effects.
The only precaution is avoiding light therapy if you take medications or have conditions that make you sensitive to light. Otherwise, it is considered very safe with no known long-term risks.
Proper eye protection is important, always follow device instructions carefully. It’s a good idea to start with short treatment sessions (5-10 minutes) and then gradually increase the time if needed.
How Should You Use Red Light Therapy for Hair Growth?
To stimulate hair growth, it is recommended to use red light therapy for at least 12 weeks. Here are some tips on using red light therapy at home to stimulate hair growth:
- Obtain an LED device designed specifically for hair growth, using wavelengths of 630-670nm. Quality and safety testing are important.
- Use every other day for the best results. Daily may also be effective, but take the occasional 1-2 day break to avoid overuse.
- Session duration should be 10-15 mins for LED panels or caps, up to 25-30 mins for low-level laser devices.
- Sit or stand 1-4 inches away from LED panels during use, with the light pointed at scalp. For caps, ensure full contact across the head.
- Part hair in sections while using an LED device to ensure light reaches scalp. Partings can be altered each session.
- Apply to the whole scalp, not just thinning areas. This supports overall hair health.
- Be consistent over at least 12 weeks. Hair growth is a gradual process, so stick with it. Monitor monthly progress.
- Use in combination with other treatments like minoxidil, microneedling, and supplements for better results.
With regular use, red light therapy can help create optimal conditions for hair regrowth. Take before and after photos to help track your hair growth improvements. Results are gradual but can be impressive over time.
