What is Follicular Unit Extraction and What Other Terms are Associated with the Procedure?

Q: I am considering having an FUE procedure and have heard the phrases topping, capping, and tethering as part of the procedure. What do all these terms mean? — C.C., Hell’s Kitchen, N.Y.

A: These are all terms that refer to the types of injury that can occur to grafts during a follicular unit extraction procedure.

In FUE, a sharp instrument (or sharp instrument followed by a blunt one) is used to separate follicular units from the surrounding donor tissue. Forceps are then used to remove the follicular units from the scalp.

Topping occurs in the first step when the doctor accidentally cuts off the top of the graft so that the remainder of the graft cannot be removed.

Capping occurs when the doctor grabs a graft with forceps and the top of the graft (the epidermis and upper dermis) pulls off, leaving the rest of the graft behind.

Tethering occurs when the bottom of the graft is still attached to the deeper tissues after the first step causing the follicular unit to pull apart during extraction.

It is now known that hair grows in groups of one to four hairs.
