Her Backstory: Alexandra, 28, had not so much as snipped a split end since 2006. She became seduced by the versatility of her long hair—pulling it back or letting it air-dry into smooth waves—and she felt that it was her defining feature. "I like to look distinct, and my long hair is definitely dramatic," says Alexandra. "It's comforting, too. I can cover my body with it. In the summer, I literally use it as protection—spreading it over my arms to block my fair skin from the sun."
