Red Light Therapy for Hair Loss – Everything You Need to Know

Laduora DUO Red Light Therapy Hair Growth Brush

Hair loss, a common presenting symptom in the dermatology practice, affects males and females of all ages. The most common form of hair loss is androgenetic alopecia (pattern hair loss), which increases with age. According to the American Hair Loss Association, by the age of 35, two-thirds of American men will have some degree of appreciable hair loss, and by the age of 50, approximately 85% of men will have significant hair thinning.

Some studies have estimated the prevalence of female pattern hair loss to be 6% in women less than 50 years of age and 38% in those more than 70; however, other studies have shown a prevalence as high as 32% in women more than 20 years of age

While hair loss is one of the most common reasons for dermatological consultation, there are few options for treatment. And the treatments that do exist are often invasive, expensive, ineffective, or all of the above. 

There is some good news, however. Exciting new research is showing red light therapy to be a safe and effective treatment for hair loss. Before we get into the specifics of red light therapy and hair growth, let’s get a handle on how we grow hair - and how so many of us come to lose it.   


Red light therapy is a natural treatment designed to help with many issues, including hair loss.

Over the past few years, red light therapy gained popularity with the general public and healthcare professionals. The amount of evidence that supports this treatment helped with distinguishing red light therapy from other fads. What’s best, however, is the lack of any side effects after using red light therapy.

In this article, we will cover the research around red light therapy and hair loss, then we’ll take a look at some of the features that come with Laduora DUO.

How Red Light Therapy Helps Treat Hair Loss

In a number of peer-reviewed clinical trials, researchers found that red light therapy is a safe, effective way to manage hair loss.

The device emits concentrated wavelengths of natural light to your scalp. There is no UV light, chemicals, or heat involved in the process. The nature of the emitted light is near infrared light treatment, which was found to reduce oxidative stress and improve blood flow. It also stimulates the production of energy by the mitochondria.

Eventually, the process of producing energy more efficiently accelerates healing and dampens inflammation. For hair loss, red light stimulates the dermal papilla, which are the cells responsible for regulating the healthy hair growth cycle.

In a 2019 meta-analysis, researchers examined 8 clinical studies that consisted of 11 double-blind randomized controlled trials. The analysis of these trials demonstrated that individuals who received red light therapy experienced a significant increase in hair density. Researchers compared these results with other therapies, including placebo treatments.

Androgenetic Alopecia and Red Light Therapy (for males)

To examine the effects of red light therapy on hair loss, researchers conducted a 6-month study back in 2019. The study analyzed male pattern baldness and the expression of specific proteins.

The participants received 25 minutes of red light therapy every other day for 6 months. Protein analysis showed a significant increase in hair growth-promoting compounds. This led researchers to deduce that red light therapy helped participants with androgenetic alopecia through the activation of dermal papilla cells.

In another study, scientists attempted to objectify the effectiveness and safety of red light therapy on males with androgenetic alopecia. Overall, the study included 44 participants, which were divided into two groups:

  1. The first group – Red light therapy for 16 weeks (a session every other day)
  2. The second group – Sham treatment

The final analysis of the study showed these results:

  • A significant increase in hair count in the first group after treatment
  • A 35% increase in hair growth in the first group
  • No side effects were reported

Androgenetic Alopecia and Red Light Therapy (for females)

Female pattern baldness has always been a challenging condition to manage. However, many scientists redirected their focus to treating this condition, which led to some ground-breaking work. Red light therapy is one of the suggested treatments for female pattern baldness.

To avoid generalizing the results of male pattern baldness, a group of researchers conducted a similar study on females. This double-blind, randomized clinical trial included 47 female participants with hair loss. One group received red light therapy for 16 weeks, whereas the other one received a sham treatment.

Interestingly, the results for females were superior to males when it comes to hair growth. Here are some of the observed results:

  • A significant increase in hair count in the first group after treatment
  • A 37% increase in hair growth in the first group
  • No side effects were reported 

How you can benefit from Red Light Therapy For Hair Growth At-Home

Red light therapy is a great way to address hair loss, and the research backs up this statement. However, you can further optimize this process by getting a device with additional features.

Laduora DUO Red Light Therapy and Microcurrent Hair Care Brush

Scalp Care

Scalp care is indispensable for hair health. If your scalp is malnourished or contains buildups of toxins, hair growth will certainly get hindered. You need to make sure that your scalp contains all the nutrients it needs to promote hair growth.

Give yourself a Scalp Massage

When you buy hair products you often forget where hair begins: the scalp. A healthy scalp also supports optimum hair growth, says Bauman. Research suggests utilizing scalp massages can help lower blood sugar, blood pressure and heart rate. You can stimulate hair growth by taking a scalp massage if possible. This increases the circulation to scalps, increases the resiliency of roots, and helps nutrients to enter the follicle faster.

Fortunately, Laduora DUO features a warming scalp massage that stimulates blood flow to your scalp. This is one of the most effective ways to boost hair growth. Without oxygen and other nutrients, your hair follicles will simply not grow. In fact, many hair growth techniques and products focus solely on boosting blood flow to the scalp.

Microcurrent Therapy for Hair Growth

Recently, a variety of safe and effective non-pharmacological methods have been introduced as new treatments of alopecia. Micro-current electrical stimulation (MCS) is one of them. It is generally known to facilitate cell proliferation and differentiation and promote cell migration and ATP synthesis. Micro-current electrical stimulation produced by Laduora™ DUO stimulates the scalp and also activates the sebaceous glands. These glands produce sebum, a natural substance that moisturizes the scalp and kills bacteria which eliminate dandruff and scalp itchiness which rejuvenates the hair follicles.

This process can be performed daily to encourage the regrowth of lost hair and prevent additional hair loss.

Micronutrient Delivery

Washing your hair with a shampoo that claims to reverse hair loss is great and all; however, what good does it do if the nutrients never make it to your scalp?

The Laduora™ DUO device has multiple features that ensure the nutrients get straight to your hair follicle cells. Providing these cells with the necessary building blocks is irreplaceable if you want to stop hair loss. An interesting feature about this device is e-stim. This stands for electrical stimulation, which sends tingling signals through the scalp to promote hair growth and administer nutrients.

The purpose of this step is to stimulate dormant hair follicles that are in the non-growth phases.

Elixir Pod Technology

The elixir pod that the Laduora™ DUO features is a game-changer! Delivering nutrients directly to the scalp and promoting hair growth on the molecular level made this technology very popular. However, not all devices are made equally.

Laduora DUO Red Light Therapy Hair Device Pod

Laduora™ took years of extensive research and prototypes before landing on this design, which offers maximal functionality and benefits for people with hair loss.

Takeaway message

Red light therapy is a fantastic way to stimulate hair growth and reverse certain types of alopecia. There is an abundance of evidence to support the effectiveness of this treatment. Optimally, you would get a device that offers other options, including micronutrient delivery and the elixir pod technology.

We hope that this article helped you understand the potential benefits and uses of red light therapy in the field of hair loss.
