Can red light help against hair loss? An expert clarifies
If you lose hair, it is not a good feeling for many people. But what can help? Does red light act against hair loss? One dermatologist has helpful information.
Hair loss can have different reasons – therefore possible help can also be different. How effective is treatment with red light against hair loss? Dr. med. Alice Martin explains that starwhat to consider.
She says: “Hair loss can have very different causes. Some cannot be treated, some need medical therapy. For others, it depends on whether an event was the trigger, such as a delivery, menopause, medication or other. With these causes, the hair can grow again after a certain time.”
In some reasons of hair loss, red light therapy can help, explains the expert. There are also studies. One of these says that androgenetic alopecia (AGA) leads to a thinner head hair and affects around 60 to 70 percent of the adult population worldwide. With this type of hair loss, red light, more precise red light with 650 Nm (nanometer), can stimulate hair growth.
However, Martin adds: “This type of therapy can have positive influences. However, there are still no large randomized studies. It is usually also subjective feeling.” Although there is a proven effect, whether it is clearly visible and in which types of hair loss red light is not clear.
Red light against hair loss: How does it work?
To explain: Both red light therapy for specialists and specialists and devices for home use should stimulate the hair follicles, increase blood circulation in the scalp and stimulate cell metabolism. The devices usually rely on red light of 650 Nm or on low laser therapy (LLLT). It has already been proven that LED devices can ensure improved complexion and reduce inflammation, more about this.
Devices with red light for hair growth: experiences
Even in the event of hair loss, red light can be supportive and stimulate cell metabolism on the scalp, which can be promoting for hair growth. Experience with such devices can only be found online because they are not available for too long for home use.
A popular device is that . A user writes about her experience with the device that she “found a significant reduction in hair loss and a significant increase in hair growth”. She explains that she also increased her iron and vitamin D content and used the device every day. This has led to an increased re -growing speed of her hair, she writes. Many others also report positive experiences. Negative: The device is a bit bulky and sometimes gets tangled in the hair.
To the device: the is operated by a spectrum of red light (620-660 Nm). These wavelengths are intended to activate the hair follicles, reduce inflammation, reduce dihydrotestosterone (DHT) mirror (a hormone that is responsible for hair loss and thinner hair) and improve the blood circulation of the scalp. It is like devices at the dermatologist or dermatologist.
There are also other products that should work with red light and have similar effects. This includes or also head massage devices, such as from or that also work with red light therapy and also massage the scalp and can also be used in small places. They are usually a little more manageable, but they have to be moved manually over the head. There are also devices that work with electrical stimulation, as from. These also have to be used regularly.
Dr. med. Alice Martin says to the devices for home use: “As first therapy, I would not recommend it and am a bit reserved in terms of the effect of such devices. Especially since you have to use them regularly.” The dermatologist continues: “If nothing has helped and you have the financial means, you can certainly try out such devices.”
Important: Such devices must be used regularly so that they can deliver results. At least three times a week, better five times and in the very best case you should be used every day. A treatment time of around ten to 15 minutes is recommended. As a rule, such devices cannot harm, but they should not be used longer than recommended and you should never look directly into the red light. In the event of itching, redness or other abnormalities, a doctor should always be consulted. This course makes sense anyway in the first signs of hair loss, explains the dermatologist.
What can still help with hair loss?
Since red light devices against hair loss can be expensive in the purchase and have to be used regularly, it is important to know whether they can work. Dr. med. Alice Martin advises the following procedure in the event of hair loss: “In a first step, we always try to clarify what the causes of hair loss can be. In the case of a diffuse hair loss, for example, if there are hair everywhere, we ask for triggering such as stress or others.” Nutrition also plays a role, such as diets, as well as medication, diseases or other. Genetic causes are also possible. After the anamnesis it goes to the next step.
“We then take a closer look at our heads with different methods.” Only then can it be determined in more detail what kind of hair loss and whether you have to counteract medication or whether a change in diet or the use of LED and/or massage products can be suitable. Dr. med. Alice Martin Dem star also explained.
She says: “There is no miracle cure. This is also not possible. If hair is gone, you have to grow back again.” In addition to medical advice, the right approach and patience are needed.
