How Much Density Can Hair Transplant Surgery Realistically Achieve without Compromising Hair Growth Yield?

9/14/2009 12:45:58 PM


I've noticed that among the surgeons recommended on the Hair Transplant Network, some claim to be able to achieve densities as high as 90 FU/cm2, whereas others claim they can only achieve half that amount. As they all seem otherwise equally competent, it makes the choice very easy. Can 90 FU/cm2 really be achieved?


Just about anyone can make 90 incisions with small refined tools per square centimeter of a bald scalp. But getting all the hair into the recipient sites and getting them to grow is another story.

Assuming a hair restoration physician can get them to grow, ultra high densities are still only appropriate for a select group of patients. Even physicians recommended on the Hair Transplant Network who claim to be able to transplant the highest densities will tell you that. Frankly, transplanting 90 FU/cm2 in the hairline of a Norwood class 5 patient would be downright irresponsible. Additionally, because vascularity plays a major role in determining if a patient is a candidate for ultra high densities, certain conditions or characteristics may prevent physicians from transplanting such high densities even if they appear to be good candidates otherwise.

Keep in mind too that the number of hairs per follicular unit will ultimately impact the hair density that can be achieved per square centimeter. For instance, transplanting 40 2 haired FU/cm2 is the same hair density as transplanting 80 single haired FU/cm2.

That said, the skill and experience of the hair replacement physician is crucial in getting ultra high density hair to grow. Trimming healthy ultra refined grafts and creating tiny incisions at an appropriate angle for a snug fit without compromising the scalp's vascularity is critical.

Even still, most leading hair restoration physicians will tell you that risks of lower yield increases as density increases. However, it's been agreed by some of the most reputable hair transplant surgeons in the profession that more study is required to determine how much density can be achieved without compromising hair growth yield.

I hope this helps.
