Kuznetsova asked the umpire to supply her with a pair of scissors to carry out her impromptu haircut.
WTA Finals Singapore Round- Robin stage Elimination match is between Agnieszka Radwanska & Garbine Muguruza on Wednesday.
"I was trying to stay and hang in there and play every point".
"Every time I would hit a good shot, it would hit my eye every time and I had [to] struggle", she said, according to the Guardian.
"I thought, 'okay, what's more important now - my hair which I can let grow or the match?'"
"It was bothering me a lot", she admitted during the post-match press conference. "I think hair is not very important".
The first match of the day between Pliskova and Kuznetsova gets under way at 7.30 pm Singapore Time (5 pm IST) on October 26.
Kuznetsova, who qualified for the season-ending tournament by retaining her Kremlin Cup crown on Saturday, beat the Pole 7-5 1-6 7-5 in a stamina-sapping match, but it was her behaviour in the deciding set that stole the show. "Good thing she didn t cut her anything else".
Kuznetsova was a break up on three occasions in a final set that saw both players fail to serve out the match.
Head-to-head, Kuznetsova leads Radwanska with 12 wins compared to Radwanska's 4, but Kuznetsova will obviously be more tired coming into the match.
Next up for US Open runner-up Pliskova is a clash against Svetlana Kuznetsova on Wednesday, with the Russian having also saved a match point in beating Agnieszka Radwanska. It is not the first time a tennis player has taken action after being distracted by their own locks on court.
After a hold to love extended her lead to 4-1, it all appeared to be going the defending champion's way, but Kuznetsova clawed her way back into the set, breaking in the seventh game to 30 to get the set back on serve. "I always do", she said.
"I have not been at my best these past years, but something has changed this year and I just enjoy my game, I enjoy the crowd and I enjoy playing the best players in the world", said Kuznetsova, a 2004 US Open and 2009 French Open victor who is now back in the top 10 for the first time in six years.
