Can red light therapy help with hair growth?

Hair loss affects millions of people; it may be caused as much by genetic factors or consequences associated with aging, hormones that create imbalances.  Two-thirds of all male Americans are going bald. Well, by age thirty-five at least. There are many modes of treatment so far. Red light therapy is one of today’s most potent treatments.

Red Light Therapy for Hair Growth

For several decades, red light therapy has been used in the treatment of all sorts of issues. Recently red light therapy has become popular as a way of promoting hair. However, can red light therapy promote hair growth? This article will look at the science of how to encourage more hair.

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 – Insufficient proteins, vitamins, and minerals required for best hair condition.
  • High Stress Levels – The stress hormone cortisol prolongs the resting phase and slows new growth.
  • Illnesses – Thyroid disorders, anemia, and autoimmune disease can trigger excessive shedding.
  • Medications – Blood thinners, antidepressants, start control, and different pills may cause loss of hair.
  • Inflammation – Scalp inflammation prevents proper follicle cycles.
  • Aging – With advancing years, decreased cellular interest and microcirculation gradually the increase cycle.

Although genetic elements contribute, weight loss plans, strain hormones, and cellular growth are involved in maximum individuals’ hair loss. Healthier boom cycles may be supported through a holistic technique targeting cell regeneration.

Types of Hair Loss:

There are numerous kinds of hair loss, but we’ll be aware of the two most not unusual:

Androgenetic Alopecia: Additionally called male or female pattern hair loss, this hereditary situation is a result of hormonal modifications and affects hundreds of thousands globally.
Alopecia Areata: An autoimmune ailment in which the immune machine mistakenly attacks hair follicles, leading to patchy hair loss.

What is Red Light Therapy?

Red light therapy is also known as photobiomodulation – the use of certain wavelengths of light to give some medical advantages at a cellular level. It is the process of illuminating concentrated red and near-infrared light from LEDs or lasers. After absorbing the light, it triggers the cells’ mitochondria. Mitochondria produce ATP, which is the energy that powers all activities in cells.

Besides enhancing the production of cellular energy, research results indicate that red light therapy can stimulate blood flow, decrease inflammation as well as fasten recovery rates besides improving skin health and encouraging collagen tissue repair.

The Science-Based 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 the 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 the active growth phase of hair.
  • Shortened Telogen (Resting) Phase: Red light therapy shortens the inactive resting phase for a faster return to growth.
  • Increased Growth Factors: Red light boosts growth factors like IGF-1 and VEGF for a 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 the 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.
