PDT equipment, also known as photo therapy equipment, mainly uses different wavelengths of different colored light, and the wavelength means the depth of light reaching the skin. Different skin depths have different stimulations on the human body, so they have different effects.
The red light of LED photon therapy machine mainly has a repair function, blue light is used to treat acne, and yellow light is used to improve quality sensitive skin and improve skin.
In addition to repairing the skin, the red light of LED photon therapy machine also has the functions of improving insomnia and hair growth. Today we will mainly introduce its red light hair growth function.
What is the red light hair growth theory?
Theory of red light growth:
Red light refers to visible light with a wavelength in the range of 600-700nm, which is produced by low-energy laser therapy.
Red light hair growth refers to a phototherapy that uses light in the spectral range of 600-1000nm to irradiate diseased tissues and organs in order to restore the physiological functions of tissues and organs. It has been used as an auxiliary means of treating skin, soft tissue and nerve damage in clinical practice for many years.
In 1967, Hungarian doctor Mester used a 694nm low-power ruby laser to study the potential carcinogenicity of lasers on mice, and accidentally discovered that lasers can stimulate hair growth in mice. This discovery demonstrated the efficacy of photobiotherapy for the first time. This provides a theoretical basis for red light to be used as a means of hair growth and prevention and treatment of hair loss.
Clinical theory of hair growth:
Clinical studies have found that red light irradiation can repair the scalp skin barrier, increase hair density and hair diameter, increase hair growth rate, reduce the amount of hair loss and the proportion of single hair follicle units. 640/650nm high-energy red light conducts heat energy to the scalp hair follicles, promotes local blood circulation, and promotes hair growth.
LED photon therapy hair growth theory:
As a form of photobiotherapy, LED photon therapy is widely used in the treatment of hair loss due to its non-invasiveness, low side effects and high safety. Unlike laser light sources, LED light is incoherent light with a wide wavelength range and low energy density, which is suitable for covering a large area of surface tissue. Its spectrum includes blue light (450~495 nm), red light (630~670 nm) and near-infrared light (700~850 nm). These wavelengths of light have significant potential in promoting hair growth and improving the microenvironment of hair follicles, especially for the treatment of AGA and AA.
The red light of the LED photon therapy machine has low thermal damage and comfort, suitable for long-term use, and is a safe and effective home treatment option for patients with mild to moderate hair loss. However, it has limited effect on severe hair loss and usually requires combination with other therapies. Overall, LED red light provides a convenient and safe option for hair loss treatment and is expected to become a routine method, but further optimization of treatment parameters and combined strategies is still needed.
Introduction to red light hair growth therapy.
Treatment philosophy guide:
The red light hair growth is mainly 640nm and 650nm wavelengths. There are many research articles on the Internet. Of course, after teaching and clinical practice by Liton Laser training institutions, we also concluded that red light with a wavelength of about 640nm has a hair growth function, but it is not successful in one treatment.
It requires two treatments per month, each time for about 20 minutes, with an energy of 20mj/cm2, and the effect will be seen in three months.If you need a better hair growth effect, you can apply hair growth products, which will get better results.
Before and after red light hair growth therapy:
Using LED red light therapy equipment, the treatment time is 30 minutes a day, focusing on the hairline and the top of the head. At the same time, improve your lifestyle, ensure 6 hours of basic sleep a day, perform professional scalp massage twice a week, and learn stress management techniques. This comprehensive treatment plan has achieved remarkable results.
After 2 weeks of continuous treatment, the daily hair loss can be reduced by 60%. By the 4th week, fine new hair began to grow at the receding hairline. By the 6th week of treatment, the hair density in the top of the head has recovered by more than 50%, and the overall hair volume has improved significantly.
Professional medical professor explained:
Professional doctor Professor Hong explained that the reason why red light therapy can achieve such an effect is that the red light of a specific wavelength can penetrate deep into the scalp tissue, activate the mitochondrial function of hair follicle cells, improve local microcirculation, and regulate the normal growth cycle of hair follicles. This non-invasive treatment method, combined with a healthy lifestyle adjustment, provides an effective solution for stress-induced hair loss.
It should be noted that red light therapy needs to be used for more than one month to see obvious results, and the treatment effect varies from person to person. It is recommended that friends with similar problems develop personalized treatment plans under the guidance of professional doctors to achieve the best treatment effect. Mr. Chen’s successful case proves that as long as the right method is chosen and treatment is adhered to, stress-induced hair loss can be effectively improved.
LED red light machine introduction:
This treatment uses a medical-grade LED light therapy machine, each lamp has 3W energy, and the red light radiation intensity is 140mw/cm².Hair growth requires low energy, but the energy of the LED photon therapy machine itself is not high, so sufficient energy stimulation is required. The medical-grade machine produced by Liton Laser with CFDA can fully meet the energy requirements for hair growth.

LED photon therapy machine features:
Non-invasive treatment, safe and reliable.
LED photon therapy machine uses low-energy red light (640nm) to irradiate the scalp. It does not require the use of drugs or surgery and is a safe, non-invasive treatment method. It does not damage the skin and hair, does not cause allergic or uncomfortable reactions, and does not cause any side effects or discomfort to the body. It is suitable for people of all ages with hair loss.
Highly effective in promoting hair growth.
Red light can penetrate deep into the scalp, stimulate blood circulation in the hair follicles, and improve cell metabolism, thereby promoting hair growth, increasing hair density and health, and making hair thicker and healthier.

Other laser hair growth methods.
Of course, LED photon therapy machine is more of an auxiliary function, and its hair growth effect is not the main function. In the beauty machine industry, if you want to achieve better hair growth effects, thulium laser is still recommended!
1927nm thulium laser has a great stimulating effect on hair regeneration due to its characteristics of opening the microchannel function of the skin epidermis and the thermal diffusion effect.
We demonstrated fractional thulium laser hair growth therapy to our customers at the 2024 Cosmoprof CBE ASEAN Thailand Exhibition. You can check out more: 1927nm fractional thulium laser assisted hair regrowth.

FAQs about Red Light Hair Growth:
How long does red light hair growth treatment take?
When using red light hair growth treatment, the length of irradiation time mainly depends on the size of the hair loss area and the specific needs of the treatment. Generally, the red light irradiation time ranges from 15 to 30 minutes. You can go to the dermatology department of the hospital for a clear diagnosis.
If the area of hair loss is small, the irradiation time may be shorter, usually 15-20 minutes, because a smaller area requires relatively less light energy, and a shorter irradiation time can meet the treatment needs. On the contrary, if the area of hair loss is large, the irradiation time may need to be extended to 20-30 minutes to ensure that enough energy can cover the entire treatment area.
Usually, patients need to receive 2-3 red light treatments per week to ensure that the scalp is continuously and stably stimulated, thereby promoting hair growth. It should be noted that the specific conditions and reactions of each patient may be different. Some patients may be more sensitive to red light treatment and require a shorter irradiation time to achieve the treatment effect; while some patients may need a longer irradiation time and a higher frequency of treatment to see obvious results.
During the treatment, patients should pay attention to keeping the scalp clean and dry and avoid using too many hair care products. Red light therapy is an auxiliary treatment method. During the treatment process, patients can also use medication, hair transplantation, etc. according to the doctor’s advice to achieve better treatment results.
How many treatments are needed for red light hair growth?
Using 655nm golden band LED red light to make hair grow again is not a temporary treatment method, but must be repeated at intervals to maintain the effect. The recommended treatment frequency is 3-4 times a week, with at least 1 day between each 2 times.
It usually takes about 3 months for the treatment to see obvious results, and then continue to maintain 1~2 treatments per week to maintain the smooth growth of new hair.
