8 Beauty Products a US Open Tennis Pro Actually Wears on the Court

"I prefer to wear my hair up when I’m on the court, and hair spray is a must when I compete, especially in windy conditions. In order to keep my hair from frizzing, I apply this antihumidity spray all over my hair. It works well even on the hottest, humid days and it doesn’t let my hair go wild when I play in those extreme outdoor weather conditions. It also offers UV protection for hair which is amazing! Plus, it smells fantastic."
