A frequently asked question is about the difference between various HT techniques.
We shall start by discussing the two different techniques used for extraction of hair follicles, viz., strip FUHT and stitchless FUSE/fue.

Both the techniques have their pros and cons.

FUSE

In FUSE/fue, the follicular units are extracted one by one in a random pattern.
The donor sites are left to heal on their own. There is no need of any closure as the donor sites are very small.
The picture below shows a typical scalp donor area from where the follicular units have been extracted.

The sutures will dissolve and do not have to be removed.
The strip is then dissected into individual follicular unit grafts.

A 26 gauge needle, (needle diameter being 0.45mm), is juxtaposed in the picture for sake of comparison.
As can be seen from the picture, the follicular units are extracted in a random pattern, so that no two adjacent units are extracted.
Since, there is no suture/staples, there is no suture scar.
It is, therefore, possible to buzz cut the hair, without worrying about a suture scar being visible.

On the right hand side, is a picture some of the dissected grafts, that are stored in chilled lactated ringer's fluid till they are transplanted.
These grafts are transplanted into the bald/balding area.

This step is carried out by gently sliding the hair follicular units (or grafts) into pre prepared needle slits.
