A: Hair loss in the temple area following a facelift is relatively common and can be treated with a hair transplant. If there is scar tissue, the hair restoration will generally require more than one session.

A: The answer depends upon the patient’s baldness. If they are very bald, the first session will be the most noticeable, since going from no hair to hair is much more dramatic than going from some hair to more hair. In addition, if someone is very bald, the first session is generally the largest, with less hair being transplanted in the second.

The situation is different if someone has had a hair transplant with only a limited amount of hair loss. In this case, the first session may be small (since that is all they need at the time) and the second session, performed after the person has lost additional hair, may be significantly larger.

In addition, while the impact of the first session was lessened by the progression of the person’s hair loss, the second session was superimposed on existing, permanently transplanted hair and may be more dramatic.

A: It is possible to lower the hairline with a second hair transplant, but the doctor must be certain that you have enough donor hair so that the transplanted pattern will look natural long-term.

Unless there is some pressing reason that you had to have a second session sooner, I would wait a minimum of 10-12 months between hair restoration procedures so that you can see the full cosmetic impact of the first session.

As a hair transplant matures and thickens, the hairline will look lower as the eye doesn’t see as far into the scalp.

A: Hair loss after a brow, or face lift, is quite common. If it is cosmetically bothersome, a localized hair transplant can correct the problem.

The hair can be transplanted directly into the scar (if the scar is flat) and into any surrounding areas of thinning. The complete correction may take more than one hair restoration session.

A: If a person is to become a Norwood Class 6, the hair that we have available for us to transplant is only about 12% of what was there originally. This, of course, will vary from patient to patient depending upon one’s donor density and scalp laxity and a host of other factors.

We make the hair restoration look good by restoring 25-50% in the front, and proportionately less in the back. Logically one cannot restore 1/2 of ones original density to an entire bald scalp with only a thin strip of donor hair – there is just not enough hair, even with multiple sessions.

I transplant 25-35 FU/mm2 in one session, but this is the density created in the front, not overall.

Due to follicular unit graft sorting (placing the larger follicular units in the forelock area) this provides even more density than the actual numbers suggest. If someone is relatively certain to have more limited hair loss, then the numbers can be increased, but it is risky if you underestimate the degree of eventual hair loss.
