Hair transplant for baldness is reliable. However, not all baldness caused by alopecia areata is suitable for hair transplantation, for example, acute stage of patchy baldness, alopecia areata caused by lupus erythematosus, syphilitic alopecia areata, resting alopecia areata and so on, are not suitable for hair transplantation. At present, the hair loss suitable for hair transplantation is androgenetic alopecia. For patients with androgenic alopecia, hair transplantation is recommended if various medications are basically ineffective. Hair transplantation involves transplanting hair from the occipital area to the forehead. The occipital hair is much less sensitive to dihydrotestosterone than the forehead hair. So by transplanting follicular sebaceous units from the occipital hair follicles to the top of the head, the chances of hair loss are still lower. So for baldness caused by androgenetic alopecia hair transplantation is reliable. For patients with baldness, it is recommended to go to regular hospitals for timely examination and standardized treatment under the guidance of professional doctors.
