For 21 yr old males receding of the hairline is the beginning of Androgenic Alopecia or male pattern baldness. It needs to be evaluated at this stage if the progression can be significantly delayed by means of local applications and therapies and if it had already receded to an extent that the person is not comfortable by just stopping further loss but wants a correction or in other words want to get his original hairline back then hair transplant is a straight forward and easy option and a long term solution.
