How many hairs are on an avarege adults head?

Answer 1

Assuming no balding guys, then you have the problem of hair color. Blondes have less hairs on their head then dark-brown haired people. Red-heads have a different amount too. Then, I ask, do you want to include facial hairs or just hair-cut hairs? So are we using a weighted average (10% blondes, etc.) or not? Anyway think upwards of 100,000 hairs and then there are the adjustments.
