Surgical scars on the head appearing not to grow hair can be changed by choosing surgical treatment and hair transplant surgery depending on the size of the scars. 1. Smaller scars: In the case of smaller scars, the scars can be surgically removed and then re-stitched. 2. Bigger scars: In case of bigger scars, hair transplantation can be used to plant occipital hair follicles into the scarred area, which can hide the scar and also ensure the normal growth of hair in the scarred area. Surgical scars on the head that do not grow hair are likely to have a psychological impact on the patient, because the area and depth of the scars are different, so it is recommended to go to a professional skin hospital, do a comprehensive examination, and then choose a reasonable treatment.
