Methods and apparatuses for attaching hair using surgical thread

A method for attaching hair to a human, comprising:

• inserting and advancing a sharp-tipped distal end of a cannula through an inner cavity of a flexible tube until the distal end of the cannula projects beyond a distal end of the tube;
• inserting the distal end of the cannula and the distal end of the tube through an entry point of the skin of the human;
• advancing the cannula and tube under the skin until a proximal end of the cannula and a proximal end of the tube is near the entry point of the skin and the sharp-tipped distal end of the cannula pierces the skin of the human at an exit point that is different than the entry point and the distal ends of the cannula and the tube project beyond the exit point;
• retracting the cannula from the tube via the proximal end of the tube, leaving the tube in position under the skin;
• inserting a length of barbed surgical thread through the tube so that a first portion of the length of barbed surgical thread extends through the tube and beyond the distal end of the tube and a second portion of the length of barbed surgical thread extends beyond the proximal end of the tube;
• removing the tube from under the skin, leaving in position under the skin the first portion of the length of barbed surgical thread that extends through the tube which secures a hold to tissue under the skin;
• and
• attaching hair to the second portion of the length of barbed surgical thread.
