Red Light Therapy for Hair Loss: Does It Work? | Jae Pak MD

- Reviewed by: Dr. Jae Pak, M.D.

From social media to clinical discussions, red light therapy (RLT) is touted not just for its skin benefits but also for its potential to revitalize thinning hair. But amidst glowing testimonials and sleek devices, what’s the real story? Does red light therapy actually turn the tide against hair loss, or is it just another fleeting trend?

At Jae Pak MD Medical, we dive deep into the science and practicality of emerging treatments to bring you clear, actionable insights. Let’s explore what red light therapy involves and whether it should be part of your hair restoration journey.

What Exactly Is Hair Loss?

Hair loss, or alopecia, is not just an aesthetic concern but a medical one, affecting millions globally across various forms. It can disrupt the normal hair growth cycle, impacting hair follicles and leading to hair thinning or baldness. 

Let’s break down the types of hair loss and how they might interact with treatment options like red light therapy:

  • Androgenetic Alopecia (Female and Male Pattern Baldness): This genetic form involves a progressive reduction in hair thickness, affecting the hairline and scalp’s overall hair density. It’s the most common type of hair loss targeted by treatments from topical minoxidil to laser devices.
  • Alopecia Areata: An autoimmune condition leading to patchy hair loss, which can benefit from light treatments that stimulate dormant hair follicles and improve blood flow.
  • Telogen Effluvium: Often temporary, this condition sees a significant number of hairs entering the resting phase simultaneously, usually due to stress, hormonal changes, or nutritional deficiencies.
  • Anagen Effluvium: Associated with treatments like chemotherapy, this type involves a rapid loss of hair during the growth (anagen) phase.

Each type of hair loss could potentially benefit from different therapeutic approaches, including the promising effects of red light therapy.

What Is Red Light Therapy?

Red light therapy might sound futuristic, but it’s grounded in decades of medical research. This treatment, also known as low-level laser therapy (LLLT) or photobiomodulation, uses specific wavelengths of light to trigger biological changes in the body. 

The concept is simple yet profound: light emitted at certain wavelengths is absorbed by the body’s tissues, where it can stimulate cellular repair, increase circulation, and promote regeneration.

The devices used range from handheld units to salon-style hoods, all designed to deliver precise doses of light directly to the scalp. By targeting the mitochondria, often called the powerhouses of the cell, RLT aims to energize hair follicles at a cellular level, potentially revving up the hair growth cycle and encouraging fuller, denser hair growth.

How Does Red Light Therapy Promote Hair Regrowth?

Understanding how red light therapy aids in hair regrowth involves examining its subtle yet powerful influence on cellular processes. 

Here’s how this innovative technology can support hair health:

Enhances Blood Flow

One of the primary benefits of red light therapy is its ability to boost blood circulation. When the scalp receives more blood flow, it also gets more of the nutrients and oxygen that hair follicles need to thrive. 

This increase in circulation is crucial for activating the hair follicles that might be lagging, encouraging them to shift from resting phases back into growth phases, thus potentially thickening the hairline and enhancing overall hair density.

Modulates Scalp Health

RLT helps to maintain an optimal scalp environment by soothing the skin and reducing flakiness or itchiness. This not only improves comfort but also creates a healthier base for hair to grow. By keeping the scalp condition stable, red light therapy ensures that hair follicles are not stressed by external conditions, allowing them to focus on producing hair.

Boosts Cellular Energy

As we’ve touched on, red light therapy excels at invigorating the mitochondria within hair follicle cells. This boost in cellular energy, primarily through the increased production of adenosine triphosphate (ATP), doesn’t just keep the cells functioning; it supercharges them. 

This enhanced energy supply empowers the hair follicles to extend their growth phase and improve hair quality. By optimizing the energy levels within these cells, RLT helps ensure that each hair follicle has the vitality it needs to produce stronger, healthier hair.

Supports Hair Follicle Activation

Through clinical research, red light therapy has shown potentatially promising results in activating hair follicles, especially those affected by androgenetic alopecia. Regular use of RLT has been linked with increased hair count and thickness, making it a valuable addition to hair care routines, particularly for those battling thinning hair. 

Unfortunately, most RLT devices sold are not effective as the devices do not make use of real RLT.

Who Should Consider Red Light Therapy for Hair Loss?

Curious about whether red light therapy (RLT) is right for you? It’s not a one-size-fits-all solution, but it does offer promising benefits for specific hair loss conditions. 

Here’s a breakdown of who might consider adding RLT to their hair care regimen:

Individuals With Androgenetic Alopecia

Those experiencing male or female pattern baldness may benefit significantly from RLT. This form of hair loss responds well to treatments that stimulate hair follicles and enhance blood flow, both effects of red light therapy.

People in the Early Stages of Hair Thinning

If you’ve just started to notice thinning hair, RLT might help slow down this process and stimulate regrowth. Early intervention can be key to long-term success in managing hair loss.

Users Looking for a Non-Invasive Option

For those wary of surgical interventions like hair transplants or wary of side effects from medications such as finasteride or topical minoxidil, RLT offers a non-invasive, relatively risk-free treatment alternative.

Patients With Chronic Scalp Conditions

Individuals suffering from scalp conditions that impede hair growth, such as seborrheic dermatitis or psoriasis, might find RLT beneficial as it helps reduce irritation and promote a healthier scalp environment.

What Are the Side Effects of Red Light Therapy?

RLT is hailed for its minimal side effects, making it an appealing option for those cautious about more invasive procedures. 

Yet, no treatment is without its considerations:

  • Minimal Skin Reactions: The most common side effect of RLT is a mild, temporary increase in scalp warmth or a slight reddening of the treated area. These symptoms typically resolve shortly after treatment without any lasting discomfort.
  • Eye Protection: While RLT is gentle on the skin, direct exposure to the eyes should be avoided. Protective eyewear is recommended during sessions to safeguard against potential harm from the intense light.
  • Overuse Awareness: Using RLT more than the recommended frequency may not increase benefits and could potentially lead to skin fatigue or reduce treatment efficacy. It’s important to adhere to a balanced treatment schedule as advised by a dermatologist.

Incorporating RLT into your hair care routine generally presents low risk, but it’s wise to consult with a hair specialist or dermatologist, especially if you have skin conditions or are using other treatments that could interact with light therapy. This careful approach ensures you harness the benefits of RLT without unwelcome surprises.

How Do I Use Red Light Therapy for Hair Loss?

Incorporating red light therapy into your hair care routine can be a boost for those struggling with thinning hair or alopecia. 

Here’s how to optimize your RLT sessions for the best results:

Choose the Right Device

Whether it’s a handheld unit, a cap, or a salon-style hood, ensure the device emits light at the effective wavelengths for hair regrowth, typically between 630-670 nanometers.

Consistent Usage

For optimal results, use your red light therapy device regularly. Most studies suggest a frequency of about three to four times per week, with each session lasting 10 to 15 minutes.

Direct Contact

Position the light source close to the scalp for maximum penetration of the red light into the hair follicles. This direct exposure helps stimulate the areas most affected by hair thinning.

Combine Treatments

While RLT can be powerful on its own, combining it with other treatments like finasteride can enhance overall hair regrowth results, particularly in cases of androgenic alopecia in the crown area.

Follow Manufacturer’s Instructions

Always use the device according to the manufacturer’s guidelines to avoid overexposure and maximize the benefits of the treatment.

What Are Some Other Hair Loss Treatment Options?

While red light therapy offers a non-invasive approach to improving hair health, it’s one of many strategies available to combat hair loss. For those seeking more dramatic and long-lasting results, hair transplant surgery, performed by board-certified dermatologists, can redistribute hair from fuller areas of the scalp to those with thinning. 

  • Follicular Unit Extraction (FUE): the FUE method involves individually extracting hair follicles from donor sites and transplanting them to areas experiencing thinning or balding. It is ideal for those seeking a minimally invasive approach with less scarring and downtime.

  • Follicular Unit Transplantation (FUT): Involving the removal of a strip of scalp skin from a donor area, FUT yields grafts that are subsequently transplanted to areas requiring hair restoration. This method is respected for its ability to cover larger balding areas effectively and the quality of the hair follicles implanted.

  • Protein Rich Support With Wharton’s Jelly: PRS/WJ introduces a potent blend of proteins and growth factors from the umbilical cords of consenting mothers and is designed to support robust hair growth, stimulate dormant hair follicles, and foster thicker, healthier-looking hair strands.
