1. A hair transplant device comprising:
an extraction unit including a coring needle configured to extract at least one hair follicle from a donor site;
an implanting unit removably coupled to the extraction unit, the implanting unit including a splitting needle configured to create an opening in a recipient site;
a housing coupled to the extraction unit; and
a user interface extending from the housing and moveable relative to the housing;
wherein when the extraction unit is assembled with the implanting unit, the coring needle and the splitting needle are arranged along a common axis and the coring needle and the splitting needle are axially separated such that the user interface can be displaced to drive the hair follicle from within the coring needle into the opening in the recipient site to implant the hair follicle.
