Hair restoration surgeons have long been taught that those patients who achieve 50% of original
density will look the same as those with full density. So it would appear that transplanting
anything over 50 follicular units per square centimeter would be unnecessary. The reality is
that in our experience 50% of original density does not in any way look the same as full density.
Factors such as hair shaft diameter, hair color and curl will greatly affect the appearance of
density in the final result.
In some hair transplant patients, natural and dense results can be achieved with as
little as 30 follicular units per square centimeters, while other patients will need up to 75 follicular
units per square centimeter to achieve natural density.
With dense packing, we are usually able to achieve this density in a single surgical session.
Many hair transplant clinics have to perform multiple sessions attempting to achieve natural density and in
the end produce less dense and less natural results. We have achieved consistently excellent
yields with packing at as much as 80 follicular units per square centimeter.
Hasson & Wong Hair Transplant Clinic is no longer focused on what density we can achieve technically but how we dense pack based on the amount of donor hair available and the area of thinning or
bald scalp that needs to be covered.
