Description

[Technical field]

[0001] The present invention relates to the technical field of hair growth, and in particular to a hair growth device through phototherapy. [Background technology]

[0002] Baldness and hair loss are already a concern for many adults. With the advancement of medical technology, the treatment of baldness and hair loss is becoming more and more diverse. In clinical practice, it can be roughly divided into two categories: hair growth treatment and hair transplantation. In addition to hair growth medicines and oral medications, the hair growth treatment process also includes various physical therapies and laser hair growth treatments, which can effectively alleviate the problems of baldness and hair loss.

[0003] Laser light irradiation has been used in medicine for many years, and the wavelength range of laser light used in medicine is between 600 and 1000 nm. It has relatively high penetration power and radiant energy, has significant temperature control effect and resonance effect, and is easily absorbed by objects and converted into the internal energy of the material.

[0004] The low-power laser can stimulate and irradiate the hair follicles to shrink the sebaceous glands, reduce and control the oil secretion, and improve the hair loss problem caused by excessive oil secretion. At the same time, the low-power laser can be irradiated to the hair follicles to accelerate the growth of hair, and further increase the fixation, density and flexibility of the hair itself.

[0005] Most current laser hair growth devices are designed in a helmet style, with multiple light-emitting modules installed in the cap, which can emit laser beams to illuminate the user's head, stimulating the hair follicles and causing hair growth.

[0006] In addition, most existing laser hair growth devices use laser diodes to irradiate the scalp, but the existing laser hair growth devices have a single purpose, and the hair growth effect is relatively slow and the treatment effect is not good.

[0007] In light of this, it is necessary to present a new hair growth device to address the shortcomings of existing technology. Summary of the Invention The problem that the device is trying to solve and the means for solving the problem

The phototherapy hair growth device further includes a power source, which is used to provide electrical energy to the first light-emitting component and the second light-emitting component.

Therefore, in addition to the preferred embodiments in the specification, the present invention can be widely implemented in other embodiments.

[0015] Alopecia, or hair loss, is a common condition that affects 50% of men over 40 and 75% of women over 65, but there are few proven effective treatments. The present invention utilizes red light low-level laser therapy (LLLT) to stimulate hair growth. In a preferred embodiment, the present invention uses red light with a wavelength of 630-680 nm to stimulate epidermal stem cells in the hair follicle and convert the hair follicle into the anagen phase (the stage in which hair actively grows). The present invention uses light waves of 830-900 nm, which are in the infrared light wavelength range, to improve blood circulation (improve blood flow) and promote the absorption of beauty serums applied to the scalp.

[0016] This invention uses red light low-level laser therapy (LLLT) to increase blood vessel diameter and improve blood circulation, and also protects red blood cells from oxidative stress, limiting the loss of platelets during surgery.

[0017] This invention describes a phototherapy hair growth device, which mainly combines red light (wavelength range 630-680nm) low-level laser therapy (LLLT) and infrared light waves (wavelength range 830-900nm) to stimulate scalp hair follicles and blood circulation respectively, and further promote healthy hair growth. By delivering safe and effective light energy to the scalp, the scalp is exposed to low-power laser light, which gives a limited regeneration effect to the weakened hair follicles.

[0018] Please refer to Figures 1-2. The phototherapy hair growth device 100 of the present invention is, for example, a helmet, and includes a cap body 102 as the device body, a flexible circuit board 104 on the inner surface of the helmet, which is provided with a first light-emitting component 104a and a second light-emitting component 104b that alternately generate and irradiate light waves of two different wavelengths, and a light-transmitting soft plate layer 106 as a cushion.
