In Hair Transplant, What is Effect of Dense Packing on Grafts?

March 8th, 2005

Q: Does dense packing hurt grafts?

A: There is no absolute answer to this question. In a hair transplant, dense packing has a risk of decreasing yield if there is a significant amount of photo damage to the scalp (which alters the blood supply) and if there is a tendency for the grafts to pop (this is difficult to predict pre-operatively). Very closely spaced grafts exacerbates the popping and exposes the grafts to desiccation (drying), hypoxia (lack of oxygen) and mechanical trauma from the necessary re-insertion.

That said, the skill of the hair transplant surgeon and placing team, the size of the recipient sites, and the way the grafts are dissected and trimmed all play important roles in determining graft survival in dense packing.

After Hair Transplant, How Long Should One Wait Before Second Transplant?

January 18th, 2005

Q: If a second hair transplant is performed before the first had a chance to grow could the second procedure destroy the follicles from the first?

A: Hair from the second hair transplant session would not damage the follicles transplanted in the first session, even if follicular unit grafts were transplanted in exactly the same spot as in the first session.

The reason to wait until the hair grows in, however, is so that you can better plan the subsequent hair restoration procedure. If two follicular units are placed on top of each other or very close together, you will essentially be creating a mini-graft and the results will not look natural.

We advise waiting at least 8 months between sessions with 10-12 months being ideal so that the grafts of the second session can be evenly distributed among the grafts of the first.

The extra few months not only allow the surgeon to identify all of the previously transplanted grafts, but enables him to get a sense of the “look” of the first session (i.e. the wave, the density, and how the patient will ultimately want to comb his newly transplanted hair). This is very useful in guiding the placement of grafts in the second session to maximize its cosmetic benefit.
