3 Red Light Therapy Hair Growth Device

Tired of shedding strands day after day? Want to revive your thinning hair? Medications, supplements, and even hair transplants are options, but these can be expensive or come with side effects. The good news is that red light therapy is emerging as a safe, natural way to improve hair growth and quality. Keep reading to understand the science behind it and explore the best at-home red light hair growth devices on the market. Let’s get started!

What is Red Light Therapy?

Red light therapy, also known as photobiomodulation or low-level laser therapy (LLLT), involves using light in the red to near-infrared range (typically 600-900 nm wavelengths) to stimulate cellular function and biological processes.

Red and near-infrared light are able to penetrate deep into tissue where it is absorbed by cells. This light absorption triggers responses in the mitochondria (the energy producers of cells) improving their function and ATP (energy) production.

In turn, overall cell function is enhanced. Red light has been shown to stimulate blood flow, reduce inflammation, accelerate healing, and stimulate hair growth.

Red light therapy panels or devices use LEDs (light emitting diodes) to deliver red and near-infrared light. Initially, low-level lasers were used, but LED technology has advanced allowing brighter, more efficient, and affordable at-home use.

The Science Behind Red Light for Hair Growth

There are several key scientific ways that red light promotes hair growth:

Increases Blood Flow
Red light exposure dilates blood vessels and boosts microcirculation in the scalp. This brings more oxygen and nutrients to hair follicles, removing buildup of oil and dirt. Improved blood flow allows hair to grow thicker, stronger, and faster.

Activates Hair Follicles
The photons in red light penetrate deep into hair follicles and get absorbed by cells. This stimulates cellular metabolism and activates hair follicles out of their resting phase into the active growing phase.

Anti-Inflammatory Effects
Inflammation of follicles and the scalp can inhibit healthy hair growth. Red light reduces this inflammation, protects against oxidative stress, and creates an optimal environment for hair to thrive.

Increases ATP Energy
By increasing ATP (adenosine triphosphate) production in cells, red light provides hair follicles with more energy to grow hair rapidly and heal damage. This turbocharges growth and repair.

Promotes Circadian Rhythm
Exposure to red light helps reset the body’s natural circadian rhythms. This normalization can lead to improved hormonal balance for healthier hair growth.

Who Benefits from Red Light Hair Therapy?

Red light therapy can benefit both men and women struggling with:

  • Male and female pattern baldness
  • Hair loss from aging
  • Post-pregnancy hair loss
  • Thinning from stress or nutritional deficits
  • Hair loss from medications like antidepressants, blood thinners, cholesterol drugs, and birth control
  • Damage from styles like tight braids or ponytails
  • Scalp conditions like dandruff, eczema, or psoriasis
  • Dry, brittle hair that breaks easily

Research on Red Light Therapy for Hair Growth

There is growing research demonstrating red light’s ability to improve hair growth in both men and women. Here are some promising findings:

  • In a 2014 double-blind randomized controlled trial, women with androgenic alopecia experienced a 37% increase in hair growth using a 655nm red light therapy device.
  • In a 2018 randomized, double-blind trial, it was found that compared with the control group, patients with male pattern baldness who received red light therapy had significantly increased hair thickness, hair number, and hair coverage.
  • A 2019 study found the benefits of red light therapy to be significant in treating AGA. Red light therapy can promote hair growth and reverse the miniaturization process of male androgenic alopecia (AGA) by enhancing dermal papilla (DP) cell function.
  • A 2021 study shows that 650 nm red light promotes the proliferation of human hair follicles and delays the transition of the hair cycle from the anagen to the catagen phase. It was concluded that 650 nm red light is the most effective and practical wavelength to stimulate hair growth through LLLT treatment.

While more research is still needed, current studies show red light can improve hair growth across genders and for various hair loss causes. Regular use is key to seeing benefits.

Curious how red light technology can restore your hair? Here are answers to some frequently asked questions.

How often do I need to use it?

For best results, use the device 3x per week for 10 minutes per session. Consistency is key to energize follicles and spur new growth.

When will I see results?

Many users see a reduction in shedding and new growth starting between 12-16 weeks. Results continue improving with sustained use.

Is red light therapy safe?

Red light therapy is very safe, with no adverse effects. The non-laser red light only penetrates shallowly into the scalp, so there’s no damage to skin.

How does it compare to laser devices?

Red light therapy and laser devices both use light energy to stimulate hair follicles. But lasers can cause burns or irritation. Red light therapy provides results without damage or pain.

Can it help with genetic hair loss?

Yes, red light therapy can be effective for conditions like male/female pattern baldness. The light energy awakens dormant follicles to grow new strands.
