Laser hair growth caps usually use specific laser wavelengths to act on the surface of the skin, which can stimulate blood circulation in the scalp and stimulate hair follicles, thereby promoting hair growth.
During the treatment, the scalp will be slightly irritated, and you may feel a little pain, but it is not serious, and there will be no other obvious side effects, so don't worry.
Pay attention to scalp hygiene during treatment, and also pay attention to maintaining adequate sleep, which can prevent aggravation of hair loss.
