Q: Could you tell me in case there is an infection at the donor area following a hair transplant, will it prevent the hair to grow after healing if the donor area closed by Trichophytic Closure? What are the problems which may the infection cause? — S.S., Park Slope, NY

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.
