Losing the Luster of Her Hair?

Sarah opened her locker and put away her history book, before taking out her literature books for her next class. And that's when she noticed it. Looking into the mirror attached to the inside of her locker door, she noticed that her hair looked odd. It was still blonde, but looked a little less glamorous, almost like she had forgotten to wash it and brush it. But that couldn't be, could it? She vividly remembered doing both those things. She shook her head, thinking that she must have been seeing things. Then she closed her locker door and headed to her second period class. Oddly, she didn't see Tiffany and Melissa at their lockers. Usually, they met up with each other this time of day. *Oh well,* Sarah thought. *I'll just see them at lunch.*
