Can red light therapy help with hair growth?

Hair loss affects millions of people around the world and can be caused by a variety of factors, including genetics, aging and hormonal imbalances. By age 35, two-thirds of American men will experience some degree of hair loss. To date, there are various treatments. One of the most effective treatments available today is red light therapy.

Red Light Therapy for Hair Growth

Red light therapy is a treatment that has been used for a variety of purposes over the years. Recently, red light therapy has gained popularity as a means of promoting hair growth. But can red light therapy really boost hair growth? In this article, we will explore the science behind red light therapy for hair growth.

The Causes of Hair Loss and Thinning

Hair loss results from disrupted growth cycles. Normally, hair progresses through three repeating phases:

  • Growth Phase – Active growth for 2-7 years
  • Transition Phase – Hair follicle shrinks for 2-3 weeks
  • Resting Phase – Hair detaches and sheds, then follicle rests for 3 months before re-entering growth phase

When the normal cycle gets interrupted, hair loss and thinning occur. The main culprits include:

  • Androgenetic Alopecia – Genetic sensitivity to hair-thinning hormones like DHT.
  • Nutrient Deficiencies – Lack of proteins, vitamins, minerals needed for optimal hair health.
  • High Stress Levels – Stress hormone cortisol prolongs resting phase and slows new growth.
  • Illnesses – Thyroid disorders, anemia, autoimmune disease can trigger excessive shedding.
  • Medications – Blood thinners, antidepressants, birth control, and other drugs may thin hair.
  • Inflammation – Scalp inflammation impedes healthy follicle cycles.
  • Aging – As we age, lower cellular activity and microcirculation slow the growth cycle.

While genetics play a role, diet, stress, hormones, and cellular aging contribute to most people’s hair loss. A holistic approach targeting cellular rejuvenation may support healthier growth cycles.

Types of Hair Loss:

There are many types of hair loss, but we’ll focus on the two most common:

Androgenetic Alopecia: Also known as male or female pattern hair loss, this hereditary condition is caused by hormonal changes and affects millions worldwide.
Alopecia Areata: An autoimmune disorder in which the immune system mistakenly attacks hair follicles, leading to patchy hair loss.

What is Red Light Therapy?

Red light therapy, also known as photobiomodulation, is a treatment that utilizes specific wavelengths of light to provide therapeutic benefits at the cellular level. It involves exposing the body to concentrated red and near-infrared light emitted by LEDs or lasers. When the light is absorbed, it stimulates mitochondria in the cells. Mitochondria generate ATP energy that powers cellular functions.

Besides increasing cellular energy production, studies show red light therapy can improve blood flow, reduce inflammation, accelerate healing, enhance skin health, and stimulate collagen and tissue repair.

The Science-Based of Red Light Therapy for Hair Growth

Can Red Light Therapy Help Hair Growth? Yes! Numerous studies have shown that sustained red light therapy has clear benefits for hair growth:

  • A 17-week clinical study in 2017 showed that female patients who received red light therapy (650 nm) had a 51% increase in hair count.[1]
  • A 2018 study showed that many drugs have side effects, but red light therapy does not.[2]
  • In a 6-month, randomized, double-blind trial in 2018, red light therapy was shown to be an effective, safe and well-tolerated treatment for male pattern baldness.[3]
  • A 2019 clinical trial found that red light treatment significantly increased hair growth compared to sham and placebo treatments.[4]

How Red Light Therapy Can Help Hair Growth?

By re-energizing follicles on a cellular level, red light therapy shows remarkable potential to address hair growth:

  • Increased ATP Energy Production: Red light boosts mitochondria activity and ATP in follicle cells, fueling growth.
  • Enhanced Blood Flow & Circulation: Red light promotes vasodilation and microcirculation to the scalp for better nutrient delivery to follicles.
  • Anti-Inflammatory Effects: Red light reduces oxidative stress and DHT-induced inflammation around follicles.
  • Accelerated Cellular Healing: Red light speeds repair and reversal of miniaturized follicles.
  • Hormonal Modulation: Red light helps regulate hormonal and cytokine pathways controlling hair cycles.
  • Prolonged Anagen (Growth) Phase: Studies show red light lengthens active growth phase of hair.
  • Shortened Telogen (Resting) Phase: Red light therapy shortens inactive resting phase for faster return to growth.
  • Increased Growth Factors: Red light boosts growth factors like IGF-1 and VEGF for stronger anagen (growth) phase.

How to Use Red Light Therapy to Help Hair Growth?

  • – Purchase an at-home red light device with medical-grade LED.
  • – Shampoo and dry scalp thoroughly before treatment. Apply any serums/oils after red light therapy instead of before.
  • – Position the light panel/helmet on your head for 10-15 minutes, making sure light reaches the hairline and crown.
  • – Use your red light device every other day consistently for best results. Combine with scalp massage and nutritious hair foods.
  • – Stick with the routine for at least 12 weeks before assessing results. Be patient – restoring hair takes time.
