In each surgical session, the grafts are inserted in-between existing hairs or previously placed micrografts, yielding considerably increased hair density after 4 sessions

Follicular units can generally be situated no closer than 1/16 inch from each other; closer packing would cause "popping" (extrusion) of adjacent grafts, and could interrupt the blood supply. However, normal human hairs are located much closer together than this. Thus, 3, 4, or even 5 sessions will be required to fill in these "spaces". The timing of these sessions depends, of course, on the rate of progression of loss of remaining natural hair and the needs of each patient. In general, however, sessions are spaced at least a minimum of 3 months apart in order to allow the new grafts, and blood supply, to become established.

It is important to realize that a dense result cannot be achieved with one session of follicular units. Even 3 or 4 sessions, on a fairly bald scalp, will ideally result in a "naturally thin" appearance.

The final result, under the best of circumstances (dense, coarse donor hair, with considerable remaining scalp hair) may approach your hair's original density. This is balanced, however, by the much more natural appearance of the tiny hair grafts.

The gradual increase in density from micrograft sessions 1, 2, 3, and 4 is evident
