crimp is still used to mean curly/curled hair..

at least it was in my childhood home, and i've used it that way..

Kinky is naturally curly hair, crimped, is set hair.

(Put nicely, kinky hair is "lambs wool" hair.. (especially if blond) its a common feature in the family.. (me? i need to crimp my hair, or it hangs, (or so my mother said) in rats tails..)
