Hair transplantation is a medical procedure. So it requires seriousness. That is why realistic expectations are very important. Firstly, there should be enough hair follicles on the back of the head. The follicles we take from parts of the body are not very efficient. It is unrealistic to want a hairline in your twenties. The aim of hair transplantation is to correct the appearance. If the appearance improves, you will already look younger. The results are generally very satisfactory.
