Is the Wellay Hair Laser capable of regrowing hair despite the presence of dihydrotestosterone (DHT)?

Both men and women tend to lose hair due to hormonal changes in the body. It is mainly the alterations in the metabolism of androgen in the body that brings about hair loss. Androgen is the male hormone that plays a very important role in both hair loss and hair growth. This metabolism of androgen gets involved with an enzyme, the 5 alpha reductase which tends to combine with the male hormone, testosterone to give DHT (Dihydrotestosterone). This DHT is the natural metabolite of the human body that is the main reason for hair loss.

The most important structure of a hair follicle is the dermal papilla, which is responsible for hair growth. The cell of this dermal papilla divides and differentiates to form a new hair follicle. As this dermal papilla lies in direct contact with blood capillaries of the skin, it is responsible for deriving nutrients for hair follicle growth. This dermal papilla has many receptors for androgens; where men have more androgenic receptors here than women.

It is very important for a person to have proper nutrition to maintain hair. So when DHT reaches the hair follicles and dermal papilla, it tends to prevent proteins, vitamins and minerals from providing the needed nourishment to sustain life in the hair of these follicles. With this, the hair follicles tend to reproduce at a slower rate and this in turn either shortens the growing phase of the hair follicles or lengthens its resting stage.

While DHT is the primary contributing factor in male pattern baldness and one of several possible causes for female hair loss, the US FDA has officially approved LLLT, (Low Level Laser) for its effectiveness in treating hair loss.

As you know, hair loss is caused by many different factors, however, the fundamental cause of hair loss is that the follicles are not getting enough nutrients, minerals, vitamins, etc to sustain and grow hairs. It is vital to boost nourishment to the dermal papilla, the most important structure of a hair follicle, which is responsible for hair growth.

Despite the presence of DHT, the Wellay hair laser helps to promote blood flow in the capillary vessels and thus supply nutrients, oxygen, etc to the follicles more effectively, counteracting the effect of DHT blocking the nutrients from getting into follicles.

How do I choose the best and most effective hair loss treatment laser?

Which wavelengths are able to penetrate the skin and be most effective?

The Wellay @home Hair Laser was developed jointly, through clinical research and testing, with the most renowned medical laser research centre in Korea; the Medical Laser and Device Research Center of Dankook University,  which is a leading contributor to the development of high-tech medical equipment, focusing on research in advanced laser treatments for clinical applications. The Wellay @home Hair Laser, using 21 lasers at 670nm, 780nm and 830nm, is patented as the World's first multi-wavelength therapeutic laser for treatment of hair loss.

Each different wavelength used in the Wellay @home Hair Laser has a different treatment and penetration depth into the scalp. The blood capillaries in direct contact with the dermal papilla lie in the hypodermis (the deepest inner layer among 3 layers of skin (scalp) tissue.

The 670nm wavelength laser light mainly treats the surface of the scalp and does not penetrate deeply into the scalp so the 670nm wavelength alone is not enough for effective hair loss treatment.

Longer wavelength (780nm, 830nm) lasers are able to penetrate more deeply into the skin tissue. However, substances within the skin tissue such as melanin, water and haemoglobin all absorb and weaken the laser light.

Light at 830nm wavelength is the least absorbed by those substances, which means it retains more of its beneficial power to energise the hair follicles because more of the light energy is absorbed into the blood cells to increase circulation and the delivery of more nutrients and oxygen to the follicles.

In the cosmetic and therapeutic laser device market, each treatment laser uses different wavelengths. 650nm/670nm are visible (red) light, while 780nm and 830nm are infrared light with more power and stronger penetrating ability and effectiveness.

Lasers around the 650nm wavelength are the most commonly used in cosmetic and therapeutic lasers because the light is a clear, bright red which is visible to the eye so it looks as if it really works for treatment and in fact, it actually does have a therapeutic effect. Also, the 650nm wavelength is the most widely used in the cosmetic laser market and is cheaper to use than longer wavelength lasers.

However, the more expensive infrared lasers which use 780nm and 830nm wavelengths are able to penetrate and stimulate deeper into the skin tissue and so are more effective in treatment although they are rarely used by other manufacturers of cosmetic and therapeutic lasers.

The Wellay @home Hair Laser uses one 670nm, one 780nm and one 830nm laser in each of its 7 laser clusters and is the only hair treatment laser on the market which offers this technology. The 3 different wavelengths irradiate the same area of the scalp simultaneously, each working at different layers and thus maximising the benefit and proving a more effective treatment.

I had plastic surgery but it was years ago. Can I use the hair laser?

Yes. The Wellay @home hair laser will not have any adverse effects. It's quite safe for you to use.

The only safety consideration (and it is the same with any laser) is that you need to be careful not to look directly at the laser light or directly put the laser on your eyes or eyelids.

Low Level Laser Therapy, which is the technology used in the hair laser, can be widely used for various kinds of skin troubles and for hastening recovery of open wounds, burns etc,  without any side effects. It natually promotes blood circulation in the capillary vessels of your skin and the cell activity, hence actually enhances recovery process after injury.

Is low level laser light therapy scientifically well documented?

Yes. Many clinical studies, research and experimentation were conducted before low level laser therapy use became widespread. There are more than 100 double-blind positive studies confirming the clinical effect of low level laser therapy. More than 2500 research reports are published. Looking at the limited low level laser therapy dental literature alone, (370 studies), more than 90% of these studies verify the clinical value of laser therapy.
