Hairline height can be reshaped by hairline repair surgery. The principle of hairline repair surgery is similar to that of hair transplantation, which is to transplant healthy hair follicle tissue in the occipital region, and then implant it in the hairline after certain processing. After the transplanted hair follicle adapts to the new blood supply, it will grow new hair, which can be trimmed and arranged normally, which is no different from the hair growing in the sky.
