Tennis star Carlos Alcaraz said he shaved his head before the U.S. Open to fix a haircut gone awry. As history (and these photos show), however, his hair grows back fast.

The five-time Grand Slam winner got slammed by one foe for his new style, but there's a funny story behind it.

Carlos Alcaraz was almost unrecognizable when he stepped on the court against Reilly Opelka for his first-round match the US Open. His usual bushy, mop haircut was replaced by an unexpected buzz cut as a result of a pre-game mishap involving his brother.
