Chevelure is a noun that refers to a head of hair. 

Coming almost directly from French, our word of the day has been used as a sophisticated way of referring to a person’s hair since the 15th century. Here’s an example:

I have to admit that Genevieve looked stunning when she entered the ballroom. Not only was she decked out in a long, flowing evening gown, but that chevelure on top of her head made her look like royalty.
