Hair loss is a common dermatological disease that, while not affecting the physical health of the patient, can severely affect the mental health and quality of life of the patient. The investigation of the alopecia population released by the national Weijian Commission in 2019 shows that the alopecia population in China exceeds 2.5 hundred million, the female and young alopecia trend is obvious, and 60 percent of people have alopecia in the age of 25. Alopecia has complex etiology and often medical microcirculation dysfunction, and the main manifestations include slow blood flow and blood viscosity. Existing treatment regimens include hair transplantation, oral or topical drug therapy, and low-energy laser physiotherapy.
The hair transplantation is mainly to take human hair follicles as a hair source, separate the hair follicles into single or multiple hair follicle units, transplant the hair follicles by a fine microsurgery technology, and survive on a new part to achieve the beautiful effect. However, the method belongs to invasive treatment, the transplantation cost is high, and the method is not suitable for large-area chronic alopecia patients.
Drug therapy is mainly by oral administration of finasteride and topical minoxidil. Finasteride is a medicine for treating male pattern alopecia, but has side effects of impotence, ejaculation disorder, orchialgia and the like; minoxidil is the only drug currently available for treating male and female alopecia, but is also associated with side effects such as contact dermatitis, itching and headache.
The low-energy laser physiotherapy is mainly characterized in that the laser irradiates and penetrates into subcutaneous tissues to reach the vicinity of hair follicles, so that angiogenesis near the hair follicles is activated, the angiogenesis enters mitochondria of hair follicle cells, and ATP energy is excited, so that the proliferation and the metabolism of the hair follicle cells are accelerated. However, the treatment population has certain limitations and may be accompanied by side effects such as headache, pruritus, erythema, acne and the like.
The existing hair physiotherapy instrument adopts a laser dot matrix to radiate an area to be treated with physiotherapy, and the method is limited in treatment population and accompanied with side effects of different degrees; secondly, through ultrasonic imaging diagnosis and through ultrasonic irradiation physiotherapy, the diagnosis accuracy of the method is poor, a large amount of ultrasonic coupling agent needs to be smeared during treatment, the process is complicated, and the user experience is poor.
The physiotherapy mode is high in price and accompanied by side effects of different degrees, and the contact physiotherapy mode cannot bring better treatment experience to users.
