It may be down to the spotlight on their matches or simply a practicality.
Either way, men are seemingly far more preoccupied with their hair than women at Wimbledon.
According to the tournament's hairdresser, around three-quarters of the clients who visit its salon are male players.
And some of them even pop in more than once during the two-week Championships.
Suzanne Strong, 57, has spent the last 26 years styling and trimming at the All England Club and the hairdresser, from Henfield, West Sussex, counts British teenager Laura Robson and world number one Novak Djokovic among her famous visitors.
But sisters Serena and Venus Williams have never dropped in - either preferring to use a personal stylist or doing their hair themselves.
"Women don't come in as regularly as the men," Mrs Strong said. "They would come in once and that would be it. I would say 75% (of our clients) are men."
She added: "It has always been the way here. It is what we are used to. Sometimes men will come in a couple of times during the tournament."
Robson, who was eliminated from the contest on Monday, visited the salon last week.
But the hairdressers have yet to receive a visit from British men's number one Andy Murray. "Djokovic comes in most years but Murray never comes in," Mrs Strong said.
