THE OFFICIAL POLL: Is donor density the same after strip harvesting? (Hair Transplant)

I can actually visualize two scenarios:

1. That the scalp is equally stretched over the entire donor area during a strip excision, similar to the balloon analogy, decreasing density per sq cm of hair bearing tissue. This assumes that there is NO excess scalp.

2. Secondly, that the scalp is not analogous to a balloon. Consider that the scalp may have excess hair bearing skin. visualize a piece of leather with 100,000 hairs that is 5% larger than the skull it covers. A wrinkle if you will. Remove the wrinkle without putting excess tension on the remaining leather. The skull size hasn't changed, and the leather hasn't stretched. Do you have less total hair? yes? Do you? Isn't the removed strip harvested and the hair re-planted? So now you have less leather and the same amount of hair....I digress, let's keep it simple and get back to my second scenario.

Has the effective donor density decreased? Hmmm. Let's do the math. Let's say the leather is 1000 sq centimeters. 100,000/1000= 100 hairs/sq centimeter. Now, remove the excess 5% of hair bearing leather. 1000-5%=950 sq centimeters. Let's assume the original density remained constant through out the sample. So we removed 5% of the hair as well. 100,000 hairs less 5% is 95,000 divided by the remaining 950 sq. centimeters of leather. Wouldn't that leave density at 100/sq centimeter?

Let's review

100,000/1000=100

95,000/950=100

(remember you still have 100,00 hairs-less any transection. But I wanted to keep the math simple for you mathematicians out there. Now what are you going to do when I tell you your overall density actually INCREASED )
