Dense Packing and the One-Session Philosophy

Natural hair density on a person's head is usually 60 - 120 hair root groups per square cm, though density varies in different parts of the scalp. It follows that hair density plays an important role in any hair transplantation. The hair density achieved through hair transplantation is decisive in achieving an aesthetic natural-looking result. So-called Dense Packing involves implanting FUs in a certain density in a certain recipient area.

A personal decision: low, medium or maximum density

The surgeon plays around with hair density, implanting donor hairs as sensibly as possible and doing his best to achieve a result looking as natural as possible. This attempt to mirror natural hair as far as possible is very patient-dependent, taking three factors into account:
  • The possibilities available under the circumstances and the availability of donor hair
  • Future age-related hair loss - the recipient area should remain looking pleasing and natural in the long term
  • The overall concept determined beforehand


It is understandable that any patient will have his own wishes and objectives. However there are not always sufficient donor hairs to fulfil patient hopes. Using the right technique, an experienced hair surgeon will be able to create the optical illusion of high density with just a few hairs, using donor hairs as efficiently as possible. A higher number of transplanted grafts does not necessarily mean greater naturalness, as hair density is not something that can be measured. Much more, it is subject to how it is seen. It is quite possible for a patient with excellent donor hair and a seemingly low density of about 40 hair root groups per cm² to achieve a result looking more natural than a patient with a much higher density and/or with worse donor hair.
