The light source area 32 is arranged corresponding to the irradiation port 61, and the red light emitted by the light source area 32 is emitted through the light-transmitting cover body 4 and the irradiation port 61 facing it, so as to act on the user's head to achieve hair growth treatment.

[0042] In order to adapt to the head shape and irradiation angle requirements of different users, such as Figures 5 to 6As shown, a rotating assembly is provided between the front inner shell 11 and the rear outer shell 22, and the rotating assembly includes a first rotating shaft portion and a second rotating shaft portion 8.

When the hair growth cap is worn on the head shape of different users, the angle position of the front inner shell 11 or the rear outer shell 22 can be adjusted according to the head shape, so as to adapt to the wearing and use of users with different head shapes, thereby improving the flexibility and convenience of use, and the light irradiation angle can be changed by adjusting the angle position of the front inner shell 11 or the rear outer shell 22, so as to ensure that the light can accurately and evenly irradiate every part of the scalp, thereby improving the hair growth effect.

Preferably, the material is PP (polypropylene) or ABS (acrylonitrile-butadiene-styrene copolymer), but is not limited thereto.

[0047] like Fig.10 As shown, the present invention also provides a control method for a rotatable OLED hair-growth cap, which is applied to the above-mentioned rotatable OLED hair-growth cap, comprising:

[0048] S101, acquiring an input irradiation control signal in real time;

[0049] S102, applying a preset voltage and a preset current to the surface light source according to the illumination control signal and timing;

[0050] S103: When the timing time is greater than or equal to the preset usage time, stop applying the preset voltage and the preset current to the surface light source.

[0051] It should be noted that the surface light source is an OLED. When the user inputs an irradiation control signal, a preset voltage and a preset current are applied to the OLED of the OLED hair growth cap, so that the OLED emits a corresponding red light spectrum and acts on the user's head to perform hair growth treatment, and the use time is counted; when the time reaches the preset use time, the preset voltage and preset current are stopped from being applied to the OLED to control the OLED to stop irradiation. The preset use time is preferably 20 minutes, but not limited thereto.

[0052] Preferably, the preset voltage applied to the OLED is in the range of 5-5.5V, and the preset current is in the range of 0.3-0.35A, corresponding to the parameter range of the above OLED. When the preset voltage applied to the OLED is 5V and the preset current is 0.3A, the red light spectrum emitted by it is as follows: Figure 3 As shown, the corresponding OLED has a peak wavelength of 625nm, a half-peak bandwidth of 51nm, an irradiation power density of 4.5mW / cm2, a luminous flux of 47.9lm, and a color rendering index of 38.2. The OLED hair cap has a wide luminescence peak with a spectral half-peak width of 51nm.

[0053] Based on the above parameters, the optimal exposure time for the OLED hair growth cap is 20 minutes per day, and the effects are as follows:

[0054] (1) After the subjects used it for 4 weeks, the hair loss count decreased by 35.1%; after the subjects used it for 8 weeks, the hair loss count decreased by 55.8%, which proves the efficacy of the OLED hair growth cap of the present invention in inhibiting hair loss.

[0055] (2) After using the device for 4 weeks, the hair density of the subjects increased by an average of 60.3%; after using the device for 8 weeks, the hair density of the subjects increased by an average of 131.4%, which proves that the OLED hair growth cap of the present invention has the effect of hair growth.

[0056] (3) After the subjects used it for 4 weeks, the average decrease in scalp oil content was 5.37%; after the subjects used it for 8 weeks, the average decrease in scalp oil content was 6.75%, which proves that the OLED hair growth cap of the present invention has the effect of reducing scalp oil secretion.

[0057] The existing laser hair growth products were tested on human hair growth under the same conditions, and the test results were as follows:

[0058] (1) After using the product for 4 weeks, the hair loss count decreased by 12.5%; after using the product for 8 weeks, the hair loss count decreased by 16.7%.

[0059] (2) After using the product for 4 weeks, the subjects’ hair density increased by an average of 51.8%; after using the product for 8 weeks, the subjects’ hair density increased by an average of 125.9%.

[0060] (3) After using the product for 4 weeks, the average decrease in scalp oil content was 1.2%. After using the product for 8 weeks, the average decrease in scalp oil content was 4.08%.

[0061] Through the comparison of the above usage effect data, compared with the existing laser hair growth products, the present invention has the characteristics of more uniform light emission, stronger penetration ability, better cosmetic effect, and better effects of inhibiting hair loss, hair growth and reducing scalp oil secretion.

[0062] Preferably, when the preset voltage applied to the OLED is 5.1V and the preset current is 0.35A, the corresponding peak wavelength of the OLED is 626nm, the half-peak bandwidth is 51.8nm, the irradiation power density is 4.5mW / cm2, the luminous flux is 42.8lm, and the color rendering index is 38.9. Under the same conditions, the effects of the subjects are as follows:

[0063] (1) After using the product for 4 weeks, the hair loss count decreased by 29.4%; after using the product for 8 weeks, the hair loss count decreased by 41.1%.

[0064] (2) After using the product for 4 weeks, the subjects’ hair density increased by an average of 57.1%; after using the product for 8 weeks, the subjects’ hair density increased by an average of 146.4%.

[0065] (3) After using the product for 4 weeks, the average decrease in scalp oil content was 7.36%; after using the product for 8 weeks, the average decrease in scalp oil content was 6.31%.

[0066] From the above, it can be seen that the OLED hair growth cap under the parameter conditions of the present invention also has the characteristics of more uniform light emission, stronger penetration ability, better beauty effect, and better effects of inhibiting hair loss, hair growth and reducing scalp oil secretion.

[0067] To summarize, the front cap body and the rear cap body of the present invention are respectively provided with a plurality of red light emitting surface light source components, so as to carry out comprehensive hair growth irradiation treatment on the head, and the surface light source components are used as the irradiation light source to make the light emission more uniform; at the same time, the peak wavelength of the OLED used is 625nm~630nm, so as to emit uniform red light, and the half-peak bandwidth of the OLED used is 48nm~52nm, so that the wider spectrum width can penetrate the skin more deeply, so as to stimulate cells at different depths in the cortex, promote scalp blood circulation, stimulate hair follicle activity, and improve hair growth effect; compared with the existing red light emitting laser hair growth cap, the light emission is more uniform, can penetrate the skin more deeply, and effectively improve the hair growth effect.

[0068] Secondly, the present invention has diverse functions and high applicability. The front cap body and the rear cap body are movably connected.
