Is the Donor Hair Really Permanent?

My grandfather’s has what you call a Class 7 pattern and the hair around the back and sides is very thin. I asked him if his hair was always that thin and he replied that when he was my age, his rim hair was much thicker. He became bald in his later 20s. Is the donor hair really permanent?

The donor hair around the sides and the back of the head in some men is not permanent.

I have seen men like your grandfather in my office and their donor density is very low, but as they are usually coming for a hair transplant assessment, I, of course, turn them down. There is some miniaturization in the donor hair in these men and I suspect that the miniaturization process that impacted their original frontal hair extends to the donor region. These men are clearly not surgical candidates.

On very rare occasions (about once every few years) I see someone who lost hair bulk in the transplanted hair. These men have a drop in donor density as well, so I must assume that these men are losing this sacred donor hair. This introduces two more risk for patients who have transplants: (a) the loss of some of the transplants over time as the donor hair dies off, or (b) the hair becomes finer with age (a common finding). The few who I have seen that reported transplanted hair loss to me, fortunately did not lose all of their transplanted hair, but it is a risk. I have only been doing hair transplants for 20 years, a relatively short period of time in the life of my patients.

Amongst those men I have transplanted above the age of 70, they never showed miniaturization in the donor area and they behaved like the young men I transplanted. One of my most unusual patients who came to my office frequently during our Open House events, was a Class 7 patient who received 9900 grafts over 9 years and he maintained his donor density through the entire process without miniaturization. He was 74 years old.
