How Red Light Therapy Helps Treat Hair Loss

Red light therapy is a natural hair loss treatment that has been shown to be safe and effective in numerous peer-reviewed clinical studies, with many happy users to support it. If you are unfamiliar with red light and its benefits, this page gives a good overview of what it is and how it works. The short version is this: A quality LED light therapy device delivers focused, safe wavelengths of natural light to your skin, without chemicals, UV rays, or excessive heat. These wavelengths of red and near-infrared light stimulate your cells’ mitochondria like natural sunlight, reducing oxidative stress and increasing circulation, so your body is able to produce more core energy to sustain itself. feed.

Making energy more efficient throughout your body improves physical function, speeds up the healing process, and reduces inflammation and pain, as numerous peer-reviewed studies have shown. [1] It also has a major stimulating effect on dermal papilla cells, which play an important role in regulating hair growth and cycle. [2]

Research shows that red light is an effective natural treatment for hair loss
Hair loss is one of the most common effects of aging, affecting more than half of the world’s population. Over 50% of men over 40 are affected by androgenetic alopecia, or common pattern hair loss. 75% of women over 65 also suffer from alopecia. [3]

Fortunately, red light therapy offers a safe and natural option to prevent and reverse hair loss. And it’s backed by a wealth of peer-reviewed clinical studies, trials, and meta-analyses. A 2019 meta-analysis looked at 8 clinical studies, comprising a total of 11 double-blind randomized controlled trials. Quantitative analysis showed a significant increase in hair density in people treated with red light. There was a significant increase in hair growth with the red light therapy treatments compared to the sham and placebo treatments.[4]

Red light therapy more effective than hair growth drugs, with no side effects
A 2018 meta-analysis reviewed recent advances in non-surgical hair loss treatments. 22 studies were reviewed comparing red light therapy to other common treatments such as hormone-regulating drugs like finasteride and dutasteride, researchers concluded that red light therapy was the superior treatment. Importantly, while many of the drugs examined in this meta-analysis had negative side effects, red light therapy turned out to have none. [5]

Improved hair count, density, thickness and strength with red light
Another meta-analysis published in 2017 analyzed 11 studies and 680 patients treated with red light for hair growth. The researchers noted significant improvements in both hair count and hair density. Additionally, hair thickness and tensile strength were also improved in those treated with natural light. People treated with red light were asked about their experiences and overall responded very positively to the treatments. [6]

Red light proven effective for male pattern baldness compared to dummy treatment
In a single study from 2018, researchers conducted a randomized, double-blind, 6-month trial with both red light therapy and a sham device. With 100 people, they applied real red light therapy to one side of each participant’s head 3 times a week for 30 minutes, while the other side received treatment.

fictional t. At the end of the trial, the side that received red light treatment had significantly more hair coverage than the sham-treated side. Hair thickness, hair count, and hair regrowth also saw significant improvements. The researchers concluded that red light therapy is an effective, safe, and well-tolerated treatment for male pattern baldness. [seven]

Treating Male Pattern Baldness With Red Light Therapy
In 2019, researchers conducted a 6-month study that looked at men with pattern baldness and changes in protein expression in their dermal papillary tissues, which are responsible for hair growth. Participants received 25 minutes of red light therapy treatment every other day for 6 months. By examining which proteins were up-regulated, the researchers concluded that red light therapy promoted hair growth and reversed the miniaturization process of baldness by improving dermal papilla cell function. [8]

Another study to define the safety and physiological effects of red light therapy on men with male pattern baldness was conducted in 2014. 44 men participated and had a section of their scalp cut 3mm in height. The area was tattooed and photographed. One group received red light treatment every other day for 16 weeks while the second group received sham treatment. At the end of the study, the researchers found [9]:

A significant increase in post-treatment hair count in the red light treatment group
A 35% increase in hair growth in the red light treatment group
No adverse events or side effects have been reported
Treating Female Pattern Baldness With Red Light Therapy
Just a decade ago, options for hair loss solutions for women were limited. With more attention paid to hair loss in women over the past decade, many studies and treatment methods have emerged. Red light therapy is one of the most tested and proven hair loss treatments for women today.

To investigate the effectiveness of red light therapy on women with normal hair loss, one of the researchers who conducted the previously mentioned study on men decided to recreate it for female participants with hair loss. hair. The randomized, double-blind trial was conducted in the same way: 47 participating women had an area of ​​their scalp cut 3 mm in height. The area was tattooed and photographed. One group received red light treatment every other day for 16 weeks while the second group received sham treatment. At the end of the study, researchers found even better results for hair growth in women than in men [10]:

Significant increase in post-treatment hair count in women
A 37% increase in hair growth in the red light treatment group
No adverse events or side effects have been reported
Red light therapy and topicals work well together: A 2017 study looked at the effects of red light therapy compared to topical 5% minoxidil ointment, a common treatment for hair loss in women. women. The study included 45 women, divided into 3 groups: those who received red light therapy, those who received topical ointment, and a combined group. The researchers concluded that the red light therapy treatments were effective. Using both red light and topical ointment has been recommended by researchers to speed up hair regrowth. [11]

51% increase in hair count in women: Another 2017 trial investigated the effect of red light therapy on women with hair loss. The researchers used the Ludwig-Savin Baldness Scale, which was specifically designed to examine hair loss in women. They found that women receiving 650nm red light therapy saw a 51% increase in hair count. [12]

Bottom Line: Red Light Therapy Is a Safe and Effective Hair Loss Intervention
Red light therapy is a safe and effective natural hair loss treatment that has been shown to be reliable for both male and female pattern baldness in numerous studies. Across studies, red light treatments increased

hair count, increased hair thickness and helped people improve their looks and confidence levels. If you’ve struggled with hair loss and unsuccessful treatments, consider trying natural red light therapy.
