Answer
Oh boy, useless trivia! I love it!! Okay, a redhead has the least NUMBER of hairs on the head, at about 90,000, however, it is the thickest. A blonde has the greatest number of hairs on the head at about 140,000, but it's the thinnest, and brunettes are somewhere in the middle, with about 100,000 strands, and it's of an average thickness. Another interesting fact is that there may be no more "real" redheads by the year 2060.

Why do bioligist belive that gingers will be gone in the year 2060?

Answer
According to genetic scientists redheads are becoming rarer and could be extinct in 100 years.
The current National Geographic magazine reports that less than 2 per cent of the world's population has natural red hair - created by a mutation in northern Europe thousand of years ago.
Global intermingling, which broadens the availability of possible partners, has reduced the chances of redheads meeting and so producing little redheads of their own.
Although it takes only one red-haired parent to produce ginger babies, two redheads obviously creates a much stronger possibility.
Some experts warn redheads could be gone as early 2060, but others say the gene can be dormant in the reproductive system for generations before returning.
National Geographic says the gene at first had the beneficial effect of increasing the body's ability to make vitamin D from sunlight. However, today's carriers are more prone to skin cancer and have a higher sensitivity to heat and cold-related pain.
