Yes, it can. For most patients who have undergone hair transplantation, their hair will appear to be thinner during the first 3 months following their procedure and then will start to slowly grow back thicker and fuller. The result of a hair transplant procedure is; permanently denser hair under the condition that the patient does not experience further hair loss in the future. A hair transplant involves little risk as it is a minimally invasive procedure, and will add more volume to your hair as well as provide you with a younger look within almost a year. Following your procedure it should normally take anywhere from 12 to 18 months to see the final results.
