Bouchard on Monday said that the world number eight spends far too much time on his locks.
“I made fun of his hair last year,” said Bouchard.
“I don’t know how it’s different now. I just think he spends way too much time worrying about his hair.”
Raonic refused to be drawn into a debate with Bouchard after his straight sets win over Ukraine’s llya Marchenko on Tuesday.
“Next question, really. I’m not going to get into this,” he said according to AP.
