Blondes, Brunettes, Redheads -- variance in total number of hairs

Just heard a factoid from my favorite radio station stating that the average blonde female has on average of 150,000 individual strands of hair on her head, the average brunette has 100, 000, and the average redhead has 60,000.

It seems to me the answer lies in the thickness of each strand. I have been married to both a redhead (extremely thick hair) and a brunette (thick, but a bit finer in texture). Is this generally true–red equals thick, blonde equals fine, etc.?

Perhaps a blonde will be my third wife, so I can continue my research. :slight_smile:

But why? If my hypotheses is right, why? Why is red hair thicker than brunette or blonde?

Or am I totally off-base, and wrong on all “counts?”

There are two kinds of melanin: phenomelanin and eumelanin. Phenomelanin is the stuff that makes skin and hair move towards black; it’s a brownish pigment, and different amounts of it dictate color. Blondes have less; brunettes more, and black-haireds a great deal thereof. Eumelanin is a reddish pigment, and red-heads have more of it than any other hair colors.

Phenomelanin - Brown
Eumelanin - Red

Maybe this can steer towards an answer (translation: I have no bleeding idea, but have been wondering the very same thing. I, too, am a redhead, and have thick hair, but have known black-haireds who have much thicker hair than I. Maybe it has something to do with number versus thickness, as you said.).

I’ve no hard statistics to back this–just lots of dating experience–but there are very few natural blondes past the age of, say, 20 years old, male or female. Comparing bleach blondes with brunettes is meaningless.

Those numbers are interesting. I am a redhead, and my hair is long and full, but it is also pretty fine textured if it is not permed. I mean, it is thick, as in there is a lot of it but it is ‘slippery’ – it doesn’t hold curl very well and likes to slide out of barettes. Hence the perms I get, I can’t stand all of this long, slippery hair swishing around in my face.

They are interesting numbers, my question is, how did they get them?
