Professional 660nm Diode Laser Hair Growth System GCP138

The professional 660nm diode laser hair growth system GCP138 is an advanced hair restoration device specifically designed for use in hair clinics, spas, aesthetic clinics, and professional settings. This state-of-the-art red light therapy hair growth system GCP138 utilizes low-level laser therapy (LLLT) with a 660nm wavelength to effectively stimulate hair growth, combat hair loss, and improve overall hair health.

It follows that a laser hair regeneration machine can be utilized to treat a variety of illnesses, including herpes, fungal infections, and IV infections. Hence, a laser hair regrowth machine is one of the most common hair growth products that can be used by treating multiple infections and HIV. It is important to know that a laser hair regrowth machine helps in treating multiple infections, and many hair conditions. It is also a good hair regrowth machine for hair growth which is not to the scalp and hair. The professional-grade laser hair growth system offers enhanced features and capabilities compared to home-use devices, ensuring optimal results for clients seeking hair restoration solutions.

The Principle of Laser Hair Regrowth

For the treatment of hair loss, red light therapy for hair loss is safe, effective, and simple to use. (low-level laser therapy) is delivered by a device that contains panels of lasers that shine on the scalp. It is a high-end laser hair loss treatment system, based on 660nm low-level diode laser technology. The therapeutic light – energy is absorbed by the cells and the process of cell repair begins, it stimulates the production of energy at the cellular level, therefore, improving cell function. Because they do not emit heat, low-level lasers are also referred to as “cold” lasers. The light wavelength emitted from a low level laser actually will repair tissues that have impaired cellular metabolism by stimulating blood circulation, encouraging regeneration of normal healthy tissues.

Hair Growth Cycle

The growth cycle of hair

The growth cycle of hair is divided into three stages: growth period, regression period, and rest period. About 10% to 15% of normal hair is in the period of retreat and rest. The hair growth device effectively clears the pores, revitalizes and rejuvenates the aging hair roots, grows healthy hair.

hair growth device

The hair growth device supplies energy to the hair roots and helps the hair to grow. At the same time, rejuvenates the aging hair roots to grow more dense, richer, and healthier hair.

In the “growth period”, each hair grows about 1cm (1/2 inch) per month for 2 to 8 years.
Within 2 to 4 months of the “rest period”, the hair stops growing and then goes through a “regression” period of 1 to 2 weeks, and eventually, the hair falls.
The hair growth device produces provides energy to the scalp and hair roots for growing healthy, richer hair.
For natural, soft, light, thin hair, Hair Growth Laser revitalizes the hair roots, allowing hair to grow healthily, making it thick and tough, and entering the normal hair growth cycle.

Laser Hair Regrowth System Technology

The 660nm laser hair regrowth system GCP138 harnesses the power of red light at a specific wavelength of 660 nanometers. This 660nm wavelength has been proven to be highly effective in stimulating hair follicles and promoting hair growth. The 660nm wavelength penetrates the scalp, reaching the hair follicle cells and stimulating cellular activity. This promotes hair development and enhances the general health of the hair by increasing blood flow, oxygen, and nutrients to the hair follicles.

Red light therapy for hair loss

660nm red light therapy, also known as Low-Level Laser Therapy (LLLT) or photobiomodulation, is a non-invasive treatment that has gained popularity for addressing hair loss. This red therapy utilizes low-level red light at a wavelength of 660nm to stimulate hair growth by targeting the cells in the hair follicles.

The red light of this particular wavelength is thought to promote hair development in a number of ways, including:

Increased cellular energy

Cells' mitochondria absorb red light treatment for hair development, which increases the creation of adenosine triphosphate. (ATP). This increase in cellular energy may lead to enhanced cell function and hair growth.

Improved circulation

The laser hair growth treatment, based on 660nm low level diode laser technology, can aid in boosting blood flow to the scalp, which will assist the hair follicles to receive more oxygen and nutrients. This may result in healthier and stronger hair.

Reduced inflammation

The 660nm red light has anti-inflammatory properties that can help reduce inflammation in the scalp, which is often associated with hair loss.

Stimulated hair follicle activity

The therapy is thought to prolong the anagen (growth) phase of the hair growth cycle, promoting the growth of new and thicker hair strands.

Hair Regrowth Treatment Applications

Hair Regrowth Treatment Applications

Laser hair regrowth treatment, also known as Low-Level Laser Therapy (LLLT) or red light therapy, is a non-invasive and painless treatment option for patients experiencing hair loss or thinning hair.

laser hair regrowth machine uses specific wavelengths of red light, typically around 660 nm, to stimulate hair follicle cells and promote hair growth. The low-level laser light penetrates the scalp and is absorbed by the cells in the hair follicles, which encourages cellular activity and enhances blood flow. This increased blood flow provides the hair follicles with essential nutrients and oxygen, which can help stimulate hair growth and improve overall hair health.

  • Significant growth of hair
  • Reversing the aging process
  • Increase hair density and fullness
  • Increased average hair volume: 159 hair / square inch
  • Significant reduction in hair loss
  • The hair grows faster
  • Hair is easier to manage
  • The overall quality is getting better

Stimulates hair growth

The primary benefit of the 660nm laser hair growth machine is its ability to stimulate hair growth. By increasing blood flow, oxygen, and nutrients to the hair follicles, the hair growth system encourages the growth of new, healthy hair strands.

Improves hair health and strength

In addition to promoting hair growth, the 660nm laser hair growth system also helps improve the overall health and strength of your hair. The red light laser therapy increases the production of adenosine triphosphate (ATP), a molecule that provides energy to the hair follicle cells. This, in turn, helps to strengthen the hair shaft and prevent breakage.

Non-invasive and painless

Unlike surgical hair restoration methods or chemical treatments, the 660nm laser hair growth system is completely non-invasive and painless. This makes it an ideal option for those who are hesitant to undergo more aggressive treatments or who have sensitive scalps.


Over time, the 660nm laser hair growth system proves to be a cost-effective solution when compared to other hair restoration methods.

Suitable for all hair types and stages of hair loss

The versatility of the 660nm laser hair growth system is another significant benefit. The device is suitable for all hair types and can be used to treat various stages of hair loss, from mild thinning to more advanced hair loss.

The maximum energy of each laser light during continuous operation is: 100mW.

No LEDs are used because LEDs do not have hair growth effects.

The voltage of the light is between 2.7 V and 3.1 V, and the maximum current is 140 mA. This means the maximum input power is 0.4 W.

The hair growth device does not have Q-switching. The hair growth device uses cold laser technology, which is different from the lasers used in beauty treatments like eyebrow washing machines. Only cold lasers of this type can promote hair growth and prevent hair loss. If the laser energy is too strong, it can actually be harmful for preventing hair loss. Cold lasers can gently penetrate the hair follicle tissue at the root, rapidly promoting hair growth and development, repairing damage, and stimulating hair growth and development.

The laser light is from Japanese Mitsubishi’s laser light.

COOLPRETTY uses 100mW, which has stronger energy and better effects compared to 5mW.

The size of the large panel is 21.2cm * 18.2cm, with 80 lights; energy density: 80 * 100mW / (21.2 * 18.2) = 20mW/cm².

The energy density of the side panel is: 60 * 100 / (18.1 * 12.9) = 25.7mW/cm².

Yes, the 660nm diode laser hair growth system can be used alongside other hair loss treatments, such as minoxidil or finasteride. In fact, combining treatments may lead to even better results, as each treatment method targets different aspects of hair growth and restoration.
