How Does Red Light Therapy Work?

To understand how red light therapy might potentially reverse grey hair, we must look at how it works. So, when the red light comes in contact with your skin, thanks to its power, it can penetrate deep under the skin’s layers to the soft tissue and even to the muscles and bones. 

When this light penetrates the cells, it may activate the mitochondria, the cell’s powerhouse, to produce more ATP.

It is the natural energy your body produces and the main energy source for every cell in the body. With the increased level of ATP, the cells become more vital and gain quality; consequently, the tissues and organs themselves gain quality.

Moreover, another chemical may be released, nitric oxide, which might help to increase blood flow, and with increased blood flow, the tissues might heal faster.

This being said, with the positive effects red light has on the body, there are chances that it might potentially reverse grey hair with consistent and regular therapies.


As you know, all bodies are all different. Therefore, you all have different metabolism and physiology, and many other factors contribute to how often a person should do red light therapy.

With this information in mind, you should know there is not one universal rule of how sessions of red light therapy are needed, but that number varies from person to person.

So, before you start with red light therapy, the professional that’s going to do it will ask you some health-related questions that would help them determine the frequency and duration of the red light therapy for your health concern specifically.


Seeing the results is also individual. No one can say how much time you will need until you see the first results. In general, many people have reported that they have seen results after a month or two and others in four to six months.

It mainly depends on the severity of the health condition you are trying to work on, overall health, metabolism, etc.

If you want to make sure that you do not miss the first changes, you can try taking photos once every seven to ten days. Then, when you compare them after some time, you will be able to see what has changed and what has not clearly.
