Optimising Hair Transplant Density

Hair transplant density is dependent on the size of the area of scalp to be transplanted, (surface area), the number of follicles transplanted, as well as the characteristics of the donor hair, i.e. curl or wave; colour; hair shaft diameter etc. Occasionally more than one hair transplant will be required to produce the desired density/coverage.

The density of a hair transplant is critical in determining the quality of the final result. Thus, obtaining maximum follicle numbers and densely packing them during transplantation are two key goals at Newin Institute.

We are able to transplant up to 6000 grafts in a single session. However, as the amount of available donor hair is finite, patients must accept and maintain realistic expectations of surgical results in terms of desired hair density and coverage in the area to be transplanted.

Patients need to understand and appreciate what their own normal hair follicle density is and what percentage of this density (when transplanted) would be necessary to produce an aesthetically appealing and natural result. Hair density varies between individuals and is affected by area of the scalp and race. It is measured as the number of follicular units per square centimetre of scalp.

  • Average Density Caucasian – 80-100 Follicles/sq cm
  • Average Density Asian – 80-100 Follicles/sq cm
  • Average Density African – 60 Follicles/sq cm

New Conscepts in Achieving Maximum Hair Transplant Density

In the past, some Hair Restoration Surgeons have long believed that patients who achieve 50% of original density will look the same as those with full density, e.g. if density is normally 80 follicles per square cm then transplanting at 40 follicles per square cm is sufficient.

However, in the clinical situation, Dr Bosnich has found that this is not always the case, as hair shaft diameter, colour and curl will affect the final result.  In some hair transplant patients, natural and dense results can be achieved with lower densities (30 follicular units per square centimetres). However, other patients may need higher densities (50-60 follicular units per square centimetres) to achieve natural density and results.

Dense Packing during Hair Transplant Surgery

With dense packing, we are usually able to achieve this density in a single surgical session. Many Hair Transplant Clinics need to perform multiple sessions in their attempt to achieve a natural density. Unfortunately, this can be counterproductive, producing less dense and less natural results due to the multiple surgeries.

Here at the Newin Institute, we have achieved consistently excellent yields by packing as much as 80 follicular units per square centimetre. We are less focused on the absolute number we pack, and more focused on how many follicular units we can pack into a given area to be treated.

This number is affected by: the amount of donor hair available, the size of the area to be treated and whether the hair loss has stabilised or stopped. If hair loss is not stable at the time of surgery, it will affect the individual’s suitability for further surgery in the future, as the amount of available donor hair is in limited supply.
