A: In a properly performed follicular unit hair transplant, the patient can remove any bandages the day after the procedure and gently shower/shampoo the transplanted area.

The bandages do not need to be reapplied.

The reason the dressing can be removed so soon is that follicular unit grafts fit into tiny needle-size incisions that heal in just one day.

A: Widened scars can be improved in two ways: they can be re-excised to make the scar finer, or hair can be placed into the scar to make it less visible.

Excising a scar works best when the original incision was closed with poor surgical techniques. In this case, using better closure methods can improve the scar. When the scar is the result of a person being a naturally “poor healer,” a wide scar will be the result – regardless of how the incision was closed.

I often approach the problem by excising a small area first, to see if I can decrease the width of the scar. If so, I would then proceed to excise the rest of the scar. If not, I would obtain hair using follicular unit extraction (FUE) — extracting hair in follicular units directly form the scalp — and place this hair into the scar. The hair placed in the scar can also be obtained from the edges of a partially excised scar.

If a wide scar that is thickened (called a hypertrophic scar) is also excised, it will usually reoccur and may result in an even worse scar. Because of this, thick scars should be flattened with injections of cortisone prior to removing. This will decrease the chance of a recurrence.

Flattening the scar is also important to permit the growth of newly transplanted follicular unit grafts.

A: If a follicular unit transplant is performed properly (using either extraction or a strip) there should be no bumps or surface irregularities. When the hair restoration is totally healed, the recipient area should be appear as normal looking skin.

With FUE it is important to sort out the grafts under a microscope, to make sure that all of the grafts placed at the hairline are 1-hair grafts and that the larger grafts are place behind the hairline. They should not be planted without first being sorted under a microscope.

A: Infection may cause the donor incision to heal more slowly or with a widened scar after a hair transplant. It may affect any closure, Trichophytic or not.

The risk of infection after a hair restoration procedure is made worse by a tight closure, but not necessarily a Trichophytic closure, unless too much skin was removed at the edges leaving the dermis (deeper part of the skin) exposed.

A: It is a very common practice to make a second separate scar in the second hair restoration procedure. This is done to maximize the hair in the second session, and it is technically the easiest to perform. If you incorporate the old scar in the new incision, there will obviously be less hair. As long as the upper incision is still in the permanent zone, the hair quality will be good.

That said, in my practice I almost always use only one scar. The subsequent procedure would incorporate the first and extend the scar to one side or the other (or both). I generally use the old scar as one edge of the new strip so that there is only one incision into virgin scalp (rather than two).

There are a number of reasons for this technique.

1. The hair will always be taken from the mid-portion of the permanent zone, so we utilize the thickest, most stable hair
2. A line scar in this location is generally the least visible and most easily camouflaged with the persons existing hair
3. One avoids making a scar too low that increases the risk of widening the scar
4. One scar will be easier to camouflage with Follicular Unit Extraction (if this is ever necessary)
