In 4 weeks post the surgery, the hair grows long enough to camouflage the scars on the scalp. Patients are advised to wear a cap to cover their head until then. It takes 4-6 months for the transplanted hair to grow to impact the overall appearance of the person. It takes close to 12 months to witness the full impact of the hair transplant on the patient. The surgeon will stay in touch at all times to monitor, assess and guide the patient.
