Differnces in bow hair and the bow itself

[A Spotless Mind]

Hey guys.
I've always wondered what the differences are between:
-White hair
-Black hair
-White and black hair mixed
Can anyone tell me what they are?

Also, this may seem like silly question but:
Why does the bow have to be curved? What difference does it make if the bow is curved as opposed to straight?

[Bill Bentgen]

Generally, black hair is courser than white. I've seen white hair that's courser than any black hair I've used.

A bow without curve is just a club. It's the spring in the bow that makes it possible for us to do everything we do with a bow.
