My entire family and I pretty much all have brown hair. I don't know how strong of a gene it is but I'm happy I have it!

Yes there is lot of brown hair in my family too, and after all it is the second most common hair color after black hair..

I had no idea that was a fact. I can definitely believe it though. Not a personal fan of black hair.

People with brown hair are often referred as brunette.  That comes from the French term of brun, meaning brown.

There is another thing I learned. That's real interesting. Are there any similar synonyms for other colors?

Not that I know of.  But another interesting fact about brown hair is that its strand are thicker than those of fair hair, but not as much as red hair.

I wish that were so for me. Sadly, my hair is quote thin.
