Description

A kind of method and device for promoting hair growth

technical field

The present invention relates to cell proliferation technology, in particular to a method for promoting hair growth, a device for promoting hair growth, a computer-readable medium, and a hair growth cap.

Background technique

The fast pace of modern life, the high pressure of life, and the long-term excessive use of the brain have made the phenomenon of hair loss a normal state. Although the phenomenon of hair loss is not harmful to health, it seriously affects people's image.

Hair loss is not only a problem for many men, but also more and more women. According to research data, the phenomenon of hair loss is gradually showing a trend of younger people, and it will become a major problem that plagues the whole society in the near future.

Studies have found that irradiating the human body with red light with a wavelength of 635-670 nanometers has the effect of invigorating and purifying blood, and can improve and restore the physiological function of blood. Irradiating the human scalp with this red light can promote the hair follicles to expand and contract, and has a good effect on the regeneration of hair roots.

However, the existing photodynamic hair growth devices generally have problems such as too large device volume, too concentrated radiation energy, and serious heat generation, and their actual hair growth effect is not significant. The bulky and bulky device will reduce the wearing comfort of the user, and severely limit the promotion and use of the photodynamic hair generating device. Serious heat problems can easily lead to burns for users, and during use, excessively high temperature will also cause irreversible damage to the activity of hair follicle cells, which is not conducive to hair growth.

Therefore, there is an urgent need in the art for a technology for promoting hair growth, which is used to promote the proliferation of hair follicle cells in the skin, thereby promoting the growth of hair and other various hairs.

As mentioned above, all the nutrients needed by hair and hair follicles are provided by the blood at the bottom of the hair follicle and in the capillaries. Once the hair does not have sufficient nutrients, problems such as dryness, yellowing, split ends, and loss will occur.

In order to promote the proliferation of hair follicle cells to achieve the effect of promoting hair growth, the present invention provides an embodiment of a method for promoting hair growth, an embodiment of a device for promoting hair growth (hereinafter referred to as a hair growth device), and a computer Embodiments of a readable medium, and embodiments of a hair growth cap.

Those skilled in the art can understand that in this embodiment, the above-mentioned method for promoting hair growth and device for promoting hair growth can be applied to the scalp, thereby promoting hair regeneration and promoting the rapid growth of short hair into long hair. In other embodiments, the above-mentioned method and device for promoting hair growth can also be applied to the skin of other animals such as sheep, so as to promote the rapid growth of wool and other animals' hair.

Those skilled in the art can also understand that the hair growth cap provided in this embodiment may be a specific device for applying the device for promoting hair growth to hair growth. The hair growth cap can have all the features of a device for promoting hair growth. Correspondingly, in some specific practical applications, the device for promoting hair growth may also have all or part of the features of the hair growth cap.

Please refer to FIG. 1 , which shows a schematic flowchart of a method for promoting hair growth according to an aspect of the present invention.

As shown in Figure 1, the above-mentioned method for promoting hair growth provided by the present embodiment may include the steps:

101: emit high-intensity pulsed red light with a low duty cycle by an LED light-emitting unit.

As mentioned above, irradiating the human scalp with red light can promote hair follicles to expand and contract, and has a good effect on hair root regeneration. The above-mentioned LED light-emitting unit is mainly used to emit red light that can promote the expansion and contraction of hair follicles. The red light may include red visible light with a wavelength range below 780 nm, infrared light with a wavelength range close to or higher than 780 nm, or a combination of the above-mentioned red visible light and the above-mentioned infrared light.

Compared with the laser light used in the existing hair growth device, the above-mentioned LED light-emitting unit used in this embodiment can emit red light (light with a large wavelength) with adjustable wavelength more efficiently, so as to provide the user with the actual use effect. the most suitable wavelength of red light. At the same time, the LED light-emitting unit is a cold light source, and the use of the LED light-emitting unit to emit red light can also effectively save power and reduce the heating phenomenon of the hair growth device.

In addition, the above-mentioned LED light-emitting unit also has the characteristics of fast response speed. The LED light-emitting unit can accurately generate a pulsed red light waveform with better hair growth effect according to the driving signal sent by the driving circuit.

Since most of the existing hair growth devices use red light in the form of DC, taking into account the temperature tolerance of the user's skin, it is necessary to maintain the user's scalp temperature not higher than 41°C. Therefore, it is generally not possible to use DC red light with a light intensity of more than 8mW/cm ² to irradiate the user's scalp, so as to prevent the user's scalp from being burned, thereby causing irreversible damage to the hair follicle cells of the scalp. However, a large number of experimental data show that the promotion of hair growth by red light with low light intensity is not ideal, which seriously hinders the promotion and development of photodynamic hair growth technology.

Please refer further to FIG. 2 , which shows a corresponding relationship between the light intensity and the relative cell proliferation rate of skin cells according to an embodiment of the present invention.

Those skilled in the art can understand that the above relative cell proliferation rate refers to the ratio of skin cells to a cell proliferation base, rather than the absolute number of skin cells to proliferate.

As shown in Figure 2, in the same light time, different light intensities can lead to obvious differences in the proliferation rate of skin cells. After 30 minutes of continuous irradiation, the common DC photodynamic hair growth device with a light intensity of 3mW/cm ² can only promote the relative proliferation of skin cells by 10%, and the effect of promoting hair growth is minimal.

By setting up a large number of heat dissipation structures, the high-power helmet-type hair growth device can increase its light intensity to 8mW/cm ² , thereby obtaining a relative cell proliferation rate of more than 50% after 30 minutes of continuous irradiation. However, as mentioned above, the bulky and bulky shape of the helmet-type hair growth device will reduce the wearing comfort of the user, and it is easy to burn the user's scalp if it is not careful, so it will also seriously limit the promotion and use of the photodynamic hair growth device.

Compared with the red light in the form of direct current adopted by the existing hair growth device, the above-mentioned pulsed red light provided by this embodiment has the characteristics of high illumination intensity and low duty cycle. This pulsed red light with high light intensity and low duty cycle can increase the instantaneous light intensity of the pulsed red light to a level above 32mW/ ^cm2 while maintaining a low average power, thereby avoiding burns to the user's scalp. Improve the hair growth effect of the hair growth device.

Please refer to FIG. 3 , which shows a schematic flowchart of determining the illumination intensity and duty cycle of pulsed red light according to an embodiment of the present invention.

As shown in Figure 3, in the above-mentioned method for promoting hair growth provided by this embodiment, the illumination intensity and duty cycle of the above-mentioned pulsed red light can be determined by the following steps:

1011: Determine the average power of the LED light-emitting unit according to the skin temperature.

As mentioned above, the upper limit of temperature tolerance of human skin is around 41°C. In order to prevent excessive temperature from burning the user's scalp and causing irreversible damage to the hair follicle cells, in the above-mentioned method for promoting hair growth provided in this embodiment, the processing module of the hair growth device can comprehensively calculate the heat dissipation capacity of the hair growth device, or connect it to the hair growth device. The temperature sensor is used to monitor the user's skin temperature in real time, so as to determine the average power of the LED lighting unit.

Generally, considering the wearing comfort of the user and the volume of the hair growth device, the average power density of the LED lighting unit can be preferably 3-4 mW/cm ² , so as to avoid the use of heavy and bulky helmet-type designs. It can be understood that, the average power of the LED light-emitting unit can be obtained by multiplying the above-mentioned average power density and the irradiation area of the hair growth device.

Since the average power density of 3-4mW/cm ² does not generate a lot of heat, the hair growth device can simply be set in the style of a hat, which is convenient for users to wear for a long time. Compared with the bulky and bulky helmet-type design, the hat-style hair growth device can be easily worn by the user at any time, and does not bring heavy and inconvenient feeling to the user, thereby enhancing the user's enthusiasm for wearing the hair growth device.

Those skilled in the art can understand that the above temperature standard of 41°C is only a specific case provided in this embodiment, which is mainly used to more clearly demonstrate the main idea of the present invention and provide a specific solution that is convenient for the public to implement, while It is not intended to limit the protection scope of the present invention. In other embodiments, those skilled in the art can also select a higher or lower temperature standard to determine the average power of the LED lighting unit according to the user's different temperature tolerance.

As shown in FIG. 3 , the above-mentioned method for determining the illumination intensity and duty cycle of pulsed red light provided in this embodiment may further include the steps:

1012: Determine the intensity of the pulsed red light according to the proliferation rate of the skin cells.

As mentioned above, higher light intensity can better promote skin cell proliferation, which in turn promotes hair growth. Especially in some specific light intensity range (for example: around 32mW/cm ² in Figure 2), the proliferation rate of skin cells will increase sharply with the increase of light intensity, so as to achieve better hair growth effect. However, considering the limitation of the average power and wearing time of the LED light-emitting unit, it is not appropriate to increase the instantaneous light intensity of the LED light-emitting unit indefinitely.

In the above-mentioned method for promoting hair growth provided in this embodiment, the user's skin cells may preferably be tested first, and the most effective illumination intensity of pulsed red light may be determined by the proliferation rate of the skin cells.

As shown in Figure 2, under the light intensity of 32 mW/cm ² , the relative proliferation rate of the user's skin cells was significantly improved. Therefore, it can be determined that the illumination intensity of the pulsed red light most suitable for the user is 32 mW/cm ² .

Those skilled in the art can understand that the above-mentioned method for determining the intensity of pulsed red light by detecting the proliferation rate of the user's skin cells provided in this embodiment is just a preferred solution for determining the intensity of pulsed red light more accurately. The above-mentioned detection only needs to be performed once before the user uses the hair growth device for the first time to determine the most effective pulsed red light intensity for the proliferation of the user's skin cells. In the user's subsequent use process, the hair growth device can also directly use the previously determined pulsed red light intensity to irradiate the user's skin hair follicles to achieve the same hair growth effect, without having to perform the above detection step every time.

Those skilled in the art can also understand that although the corresponding relationship between the proliferation rate of skin cells and the intensity of pulsed red light varies from person to person, a large number of experimental data show that in the same application scenario (for example: promoting hair growth), each The optimal light intensity corresponding to individuals is not very different.

Therefore, in other embodiments, the above-mentioned skin cell proliferation rate test can also be performed on a large number of testers in advance to obtain a universal illumination intensity of pulsed red light (for example: 30-40mW/cm ² ), so as to promote hair in the above-mentioned During the execution of the growth method, the illumination intensity of the universal pulsed red light is directly inputted through the setting module of the hair growth device.

As shown in FIG. 3 , the above-mentioned method for determining the illumination intensity and duty cycle of pulsed red light provided in this embodiment may further include the steps:

1013: Determine the duty cycle of the pulsed red light according to the average power of the LED light-emitting unit and the intensity of the pulsed red light.

In the above-mentioned method for promoting hair growth provided in this embodiment, after determining the average power of the LED light-emitting unit and the luminous intensity of the pulsed red light, the processing module of the hair growth device may first calculate the irradiation area of the LED light-emitting unit to determine the pulsed red light. The instantaneous power of the light, and then determine the duty cycle of the pulsed red light according to the ratio of the average power to the instantaneous power. The above duty cycle of the pulsed red light can indicate the time proportion of the actual effective pulsed red light in one pulse period.

For example: in the above-mentioned method for promoting hair growth provided in this embodiment, the duty cycle of the above-mentioned pulsed red light can be determined as the ratio of the average power density (4mW/cm ² ) to the instantaneous power density (32mW/cm ² ), that is, 12.5%.

Those skilled in the art can understand that the above-mentioned average power density of 4 mW/cm ² , instantaneous power density of 32 mW/cm ² , and duty cycle of 12.5% are only a specific case provided in this embodiment, and are mainly used to clarify It is intended to demonstrate the concept of the present invention and provide a solution that is convenient for the public to implement, rather than limiting the protection scope of the present invention. In other embodiments, those skilled in the art can also use other average power and instantaneous power based on the concept of the present invention, and use this to determine other duty ratios.

Those skilled in the art can also understand that the above solution of calculating the duty ratio of pulsed red light by the processing module of the hair-generating device is only a specific case. In other embodiments, the duty cycle of the above-mentioned pulsed red light may also be directly input to the hair-growing device through the setting module after calculation by other methods.

In the above-mentioned method for promoting hair growth provided in this embodiment, the LED light-emitting unit of the hair growth device can emit high-intensity pulsed red light with a low duty cycle according to the illumination intensity and duty cycle of the pulsed red light obtained in any of the above methods Light.

Due to the different hair densities of different users, the required dose of pulsed red light also varies from person to person. Therefore, this embodiment also provides a solution for determining the pulsed red light dose and irradiation time.

Please refer further to FIG. 4 , which shows a schematic flowchart of a method for determining the dose and irradiation time of pulsed red light according to an embodiment of the present invention.

As shown in FIG. 4 , the above-mentioned method for determining the dose and irradiation time of pulsed red light provided in this embodiment may include the steps:

1014: Determine the dose of pulsed red light based on the hair density of the hair follicle; and

1015: Determine the irradiation time of the pulsed red light according to the dose of the pulsed red light and the average power of the LED light-emitting unit.

The dose of the above pulsed red light can be used to indicate the light energy (unit: Joule, J) that the user's skin hair follicles are irradiated by the pulsed red light within a certain period of time.

Experimental data show that pulsed red light can promote the expansion and contraction of hair follicles with different hair densities to regenerate hair roots and promote hair growth. Therefore, better hair growth effect can be achieved by increasing the dose of pulsed red light.

Specifically, in the above-mentioned method for determining the dose and irradiation time of pulsed red light provided in this embodiment, the processing module of the hair growth device can first count the average hair density of all hair follicles in the skin area specified by the user, and then calculate the average hair density according to the average hair density and Pre-experimental statistics to determine the dose of pulsed red light required by the user. The above-mentioned pre-experimental statistics may contain the average pulsed red light dose required to achieve a standard hair density for users of different hair densities.

After determining the pulsed red light dose required by the user to achieve the standard hair density, the irradiation time of the pulsed red light can be determined by calculating the ratio of the pulsed red light dose to the average power of the LED lighting unit.

Those skilled in the art can understand that the above scheme of determining the dose and irradiation time of the pulsed red light is only a preferred scheme provided in this embodiment, and is mainly used to remind the customer of the required dosage. In other embodiments, the user can also shorten the irradiation time to reduce the dose of pulsed red light according to his good actual use effect; or further increase the irradiation time to increase the dose of pulsed red light according to his unsatisfactory actual use effect .

As shown in Figure 1, in the above-mentioned method for promoting hair growth provided by the present embodiment, the steps may also be included:

102: Irradiate skin hair follicles with pulsed red light to promote cell proliferation of the hair follicles.

As mentioned above, irradiating the user's skin with pulsed red light can promote the expansion and contraction of skin hair follicles, which has a good effect on hair root regeneration. In order to further improve the irradiation efficiency of the LED light-emitting unit, two preferred irradiation modes are also provided in this embodiment.

In a preferred irradiation scheme, the high-intensity pulsed red light emitted by the LED light-emitting unit can be diffused by an optical diffuser disposed on the hair growth device, so that the diffused high-intensity pulsed red light can evenly illuminate the skin and hair follicles to promote regeneration. Cell proliferation of multi-hair follicles.

Please refer to FIG. 5 , which shows a schematic structural diagram of a device 50 for promoting hair growth provided according to an embodiment of the present invention.

As shown in FIG. 5 , the above-mentioned optical diffuser 52 may be disposed between the LED light-emitting unit 51 and the skin 53 . The optical diffuser 52 may be provided with a plurality of protruding structures 520, and the protruding structures 520 may be pyramid-shaped. The plurality of protruding structures 520 may be unevenly disposed on the surface of the optical diffuser 52 to achieve a more uniform diffusion effect.

Please refer further to FIG. 6 , which shows a schematic diagram of an optical path of an optical diffuser for diffusing light according to an embodiment of the present invention.

As shown in FIG. 6 , the light emitted by the LED light-emitting unit 51 may be incident from below the optical diffuser 52 and enter the optical diffuser 52 after the first refraction occurs on the incident surface 521 .

The light entering the optical diffuser 52 will be refracted and reflected multiple times on the sidewalls of the protruding structures 520 , thereby leaving the optical diffuser 52 in different directions.

Since the light refractive index of the optical diffuser 52 is generally higher than that of air, some light rays with an incident angle greater than the total reflection angle will undergo total reflection on the first refraction surface 522 , and thus all propagate toward the second refraction surface 523 . And another part of the light with the incident angle less than the total reflection angle will be partially refracted and partially reflected. The partially refracted light will leave the optical diffuser 52 from the first refraction surface 522 along the direction of the refraction angle.
