Colored hair is easier to style:
Harry Josh, who gave the girls color for the Zac Posen show using a John Frieda box dye (the goal was “rich looking,”), said that virgin hair is not necessarily better hair.
“Processed hair truly does shine differently from virgin hair,” Josh said backstage. “Virgin hair doesn’t hold texture very well. If you wave it, it goes flat.”
I will take that as vindication for the years I’ve spent dying my hair into a yellow-ish submission. Look at how great it holds a wave!
