So how does red light therapy help hair grow? What is the science behind it? What results can you expect from this type treatment.

In this article, we are going to answer all these questions. Keep reading to find out how to get your beautiful hair back.

Red Light Therapy for Hair Growth

​What is red light therapy?

​Red light therapy is a form of light therapy that involves using low power red light wavelengths emitted onto the skin. Red light can penetrate into skin to depths of 8-10 mm.

It does not produce heat so this process cannot be felt and is not painful. Red light therapy provides positive effects on cellular energy, the nervous system and metabolic processes. But how does red light therapy help to reduce hair loss and stimulate hair growth?

​Before digging into how red light therapy helps for hair loss, let’s take a look at normal hair growth and hair loss phases

​The normal hair growth and hair shedding can be split into 3 phases: anagen, catagen and telogen

  • The growth phase Anagen includes about 85% of our hair. Hair can remain in this phase for 2-6 years.
  • The follicle renews itself in Catagen phase and lasts for 1-2 weeks.
  • Telogen is the resting phase. 10-15% of our hair is in this phase, which can last from 2-4 months.

​Now you may wonder, what does red light therapy do for the hair growth process? To answer this question, let’s take a look at the mechanism through which red light therapy works.

As you know plants convert sunlight to energy using a process called photosynthesis. Our body works the same way. When red light therapy is applied, the light penetrates directly into our skin to a depth of 8-10 mm. This where our blood vessels, hair follicles and sebaceous glands are located.

At this level, red light therapy is converted to cellular energy and this cellular energy helps the rejuvenating process. This increase in cellular energy also provides positive effects on the human endocrine, immune, multiple metabolic, and nervous system processes.

Red light therapy increases blood flow (blood circulation or microcirculation) in the scalp. It stimulates metabolism in telogen or catagen hair follicles. This results to accelerate anagen hair production

​What does red light therapy do for growth and hair loss?

Produce nutrients: Red light therapy increases production of ATP (Adenosine triphosphate). ATP is the molecule that carries energy to our cells in order to help synthesize proteins and a number of nutrients that are needed for a strong, healthy hair follicle.

Increase oxygen: Oxygen deficiency in hair follicles leads to hair loss and slows the process of hair growth and tissue repair. By increasing blood flow, red light therapy helps bring more oxygen and nutrients to scalp follicles. When oxygen is stimulated, cell mitochondria reactivates - releasing APT and stimulating regrowth of hair

Reduce Dihydrotestosterone (DHT) - DHT is a male sex hormone that causes baldness in men mostly over 50. It is generated at the site of hair follicles. Red light therapy reduces DHT from the scalp and stimulates delivery of nutrients to hair follicle

​Is there scientific proof that red light therapy can help hair loss?

The Science Behind Phototherapy

​In 1967, a Hungarian professor by the name Endre Mester was experimenting whether cold laser radiation caused cancer. He shaved hair patches on a group of mice. He divided them into two groups. The first group received red laser treatment while the other group received no treatment

​Exposed mice did not get cancer. Instead, their hair grew faster than those unexposed mice. The results are called Laser Biostimulation. After this, NASA got started in researching. ​After time, the cosmetic industry took notice and red light therapy was born. A discovery on mice in a lab 40 years ago is the root of red light therapy treatments we use today.

​Some recent scientific studies on red light therapy also confirm it helps hair loss

A 2015 study published on Lasers Surg Med has concluded

​LLLT stimulated hair growth in mice subjected to chemotherapy-induced alopecia and also in alopecia areata. Controlled clinical trials demonstrated that LLLT stimulated hair growth in both men and women. Among various mechanisms, the main mechanism is hypothesized to be stimulation of epidermal stem cells in the hair follicle bulge and shifting the follicles into anagen phase

​What do you need to know before buying a red light therapy device for hair growth?

​Choosing a suitable device is one of the important things that determines the effectiveness of the treatment. Before picking a device, you must know what areas of your scalp the red light will penetrate. The device depends on your hair loss pattern.

Females often have a widening hair loss pattern so a head cap device is not a good choice. In this case, they need a dynamic device that can target wider areas of the scalp. Males tend to have a different hair loss pattern, but the advice is the same. You should choose the device that matches your hair loss pattern

​How long will it take to see results?

​It’s important to understand red light therapy is not a quick fix. It must be used consistently for a certain period of time. In all experiments it took up to 3-4 months (12-26 weeks) before stimulated hair follicles reacted.

This means one must be consistent. One session of treatment takes 15-30 minutes and needs to be done 2-4 times a week. The number of times per week to engage in a session depends on cause and hair loss advancement

​Red light therapy for hair growth – Benefits

  • Non-invasive, drug-free, and painless
  • Cost effective: one time investment for the device.
  • Saves time: You do not need to go to a hair salon. You can use the device at home.
  • You can see the result after 12-26 weeks.
  • Red light therapy can be used for both men and women.

​Red light therapy for hair loss - Possible side effects

​Red light laser treatment has no side effects but there are precautions one needs to take. One should take the following measures

  • Patients should wear glasses because red light waves have divergent beams that have potential to harm eyes when viewed directly at a close range.
  • It is advisable not to use red light therapy if you are pregnant.
  • Red light therapy over a tattoo may lead the ink to absorb energy, causing pain

​What are the recommendations when using red light therapy for hair growth treatment?

​There are many devices available on the market, which you can use to cure your hair problem. Most of them make use of wavelengths between 630 nm and 670 nm. The device falling under these categories are non-significant risk (NSR) devices. Most of these devices are handheld, and the treatment lasts for 10 to 15 minutes a few times a week. Laser treatment is safe and easy to use.

However, you have to use the device properly for a better result. Read the manual and find out more on the product before trying it out. We advise you to watch some tutorials or videos and learn how to use and handle these devices properly

​What are the best home devices for hair loss?

​Red light therapy home devices can be divided into 2 groups: handheld devices and full cap helmet-style devices. Picking the best device for you depends on your hair loss pattern.

The handheld device is more flexible, meaning you can control what areas on your scalp you want to target with the red light. However, when using it you must hold the device during treatment time.

When a laser cap is used, there’s no need to control the areas you need to concentrate on treating. It treats a large hair loss area
