Interesting fact:

Did you know that redheads have the fewest hairs? With an average of 90,000 keratin fibres sprouting on their heads, redheads have the least weight to carry around. At the other end of the spectrum are blondes with about 150,000 hairs. Brunettes and raven-hairs fall right in between with 100,000 to 110,000 cranial filaments.
