Does LED Light Work For Hair Growth?

Of course, yes! In fact, redlight light therapy appears to be one of the modern and most effective ways of treating hair loss and promoting new hair growth.

Recent studies show that red light therapy appears to be a superior treatment for people with male-pattern baldness and female-pattern hair loss.

This light therapy has also become a popular option for people who want to regrow hair, improve hair density, and promote proper hair growth.

How Does Red LED Light Treatment Work?

Red light treatment has been touted as an efficacious therapy for hair loss and thinning hair, but how exactly does it work?

Red light therapy works by emitting energy-producing light packets deep into the scalp’s skin until they reach our hair follicles.

This red light helps to produce ATP (a type of cellular energy) in the cells and surrounding tissue, which can form a healthy environment for human scalp hair to regrow again.

Additionally, when the light is absorbed by the scalp, it increases blood flow in our head. This increased blood flow can bring oxygen and nutrients to the stem cells of our hair follicles, which may help to promote healthy hair growth.

Benefits Of LED Light Hair Growth Therapy

Red light therapy treatment has been shown to have a number of potential benefits for those experiencing hair loss. Here are just a few:

  • Stimulate hair growth: Red light therapy has been shown to increase blood flow to the scalp to stimulate hair follicles, which may help to promote growth. It can also increase hair density and hair count.
  • Non-invasive: Unlike other hair loss treatments, red light treatment is non-invasive and pain-free. It’s a safe and gentle option for those looking for a treatment that doesn’t involve medications or surgery.
  • Convenient: Red light therapy is typically administered in a series of treatments, but each treatment is relatively quick and can be done in the comfort of your own home.
  • Safe: Red light therapy treatments are generally considered safe and have few if any, side effects. It’s a low-risk treatment option for those looking to address hair loss.

Will Red Light Therapy Work for All Types or Causes of Hair Loss?

Red light therapy is proven to promote hair growth, no matter what condition might cause it.

But this therapy for hair growth may be more effective for certain types of hair loss, such as male or female pattern baldness (androgenetic or androgenic alopecia), which is caused by a combination of genetics and hormones.

It can also treat alopecia areata by stimulating the scalp and increasing the number of hair follicles while improving the hair shaft quality.

Clinical trials also prove that red light treatments are effective in treating temporary hair loss after undergoing chemo treatment to hasten hair regrowth.

How Long Does It Take To Grow Hair With LED Light Therapy?

It’s important to remember that you didn’t lose hair all at once, so it’s not going to grow back overnight either.

But in general, the natural healing process induced by LED red light therapy may take 3 months before you can notice any significant results.

It’s also important to note that the length of time it takes to treat hair loss and grow hair with LED red light therapy can vary depending on a number of factors, including the severity of hair loss and the overall health of the scalp.

How Do You Get The Best Results From LED Hair Growth Stimulation?

If you’re considering red light therapy as a treatment option for hair regrowth, you must follow the advised treatment sessions.

The recommended protocol is 8 -10 treatments in two to three weeks, followed by a maintenance treatment every 1-2 months to achieve optimal results.

Keep in mind that the effects of this treatment are cumulative, which means that you’ll generally see more noticeable improvements after 8 to 10 sessions.

In order for you to see the magical hair restoration you’ve been waiting for, you must be patient and stick with it.

What Is The Best Wavelength For Hair Growth?

When it comes to using red light therapy for hair restoration, the most commonly used wavelengths are in the range of 630 to 670 nanometers.

The visible red light laser can be absorbed by the molecules in hair follicles, which can stimulate hair regeneration or regrowth through a natural biological process.

Red light is absorbed by Cytochrome C, an intracellular enzyme. This enzyme can be found in your hair follicle. They are the ones responsible for sending signals to the hair follicle to stimulate growth.

What Is The Difference Between Laser Vs LED Hair Growth?

Both lasers and LEDs have helped appoint low-level laser therapy as a leading option in non-surgical treatments for hair loss. But these two work in slightly different ways and may have different levels of effectiveness.

The main difference between laser and LED hair growth treatments is the type of light used.

Laser therapy uses a low-level laser therapy beam to stimulate the cells in the hair follicle, which can help to increase blood flow and allow hair regeneration. This therapy is often used to treat male and female pattern baldness and other forms of hair loss.

Red light therapy uses a panel of LEDs to emit low-level light waves that are absorbed by the cells in the hair follicle. This can help stimulate the production of ATP, which is a molecule that is involved in energy production in cells.

LED therapy devices are thought to be less effective at stimulating hair growth than laser therapy devices, but it is generally safer and less expensive.

What Is The Difference Between Red Vs Blue Light For Hair Growth?

Red and blue light are two different types of light that are used to promote healthy hair growth.

But they have different wavelengths and are used for distinct purposes in hair growth.

Red light is often used to stimulate hair growth and improve circulation to the scalp. This can help increase ATP production in the hair follicle and boost the production of keratin, a protein that makes our hair.

On the other hand, blue light is mainly used to kill bacteria. But research has suggested that blue light may inhibit the production of a hormone called DHT, which is believed to contribute to hair loss.

LED Hair Growth Expectations

What can you expect from using an LED hair growth device?

First and foremost, it’s important to note that LED light therapy for hair is not a quick fix. It’s a process that requires consistent use to see results.

You must also understand that red light therapy for hair growth is not a one-size-fits-all solution. Results can vary depending on the individual and the cause of their hair loss.

Some may experience an increase in hair count after using low-level light therapy as new hair begins to grow. While others may see an improvement in hair health and overall appearance.

Nevertheless, low-level light therapy will surely bring the best for you and your hair. Overall expect fuller, thicker, and much healthy hair in months to come!

LED Hair Growth Side Effects

Side Effects

Here is some good news for you!

Using red light therapy to reverse the effect of hair loss has not been connected with any adverse side effects when the devices are used accordingly.

Most LED hair growth devices in the market today are proven safe to use and FDA-cleared for treating male pattern baldness and other hair loss conditions. 

So stop worrying about it and start your journey for fuller and better hair.

Will Red Light Therapy Cause Hair to Grow in Other Unwanted Places?

Keep in mind that red light therapy will only halt further hair loss and won’t create new hair growth where there was previously none. 

It can, however, help stimulate the entire hair follicle that has stopped producing hair or has been growing very small and thin.

This can lead to healthier hair growth in those areas. Just remember that red light therapy won’t cause hair to grow where it never existed before.
