Who is Lois Boisson?

Lois Boisson is a French tennis player who first made her WTA Tour debut in 2021 when she received a wildcard into the doubles main draw at the WTA Lyon Open.

In singles, the right-handed Boisson has a career record of 132-79, plus a 2-11 record in doubles. She’s the owner of six ITF singles titles and one WTA 125 title, which came at Saint-Malo in 2024. That title led to Boisson earning the No. 152 ranking by the WTA in May 2024.

Boisson was set to receive a wildcard and make her major main draw debut at the 2024 French Open, but a week before the tournament, she tore her ACL at the Trophée Clarins.

However, Boisson’s stardom has instead exploded at the 2025 French Open, her Grand Slam debut. As a wild card, she recorded her first major wins and reached the semifinals, including victories over world No. 3 Jessica Pegula and world No. 6 Mirra Andreeva. With her success, Boisson became the third player since 1980 to make the semifinals in her first major, joining Monica Seles and Jennifer Capriati.

At the 2025 French Open, Boisson also became the lowest-ranked (No. 361) quarterfinalist and semifinalist at the tournament in 40 years.

Where is Lois Boisson from?

Boisson was born in Dijon, France. When she reached the French Open semifinals, Boisson also became the French No. 1 player.

Lois Boisson career earnings

Boisson’s success at the 2025 French Open will be life-changing in more ways than one. Financially, her tennis career will grow exponentially.

Prior to Roland Garros, Boisson had a career earnings total of around $148,000. Just by making the semifinals at the French Open, she has netted at least $785,000, per Front Office Sports, over quadrupling her career earnings in the major alone.

Lois Boisson injury history

Even outside of the fact that Boisson was playing in her first-ever major at the French Open, her run is remarkable for another reason: her injury recovery. In May 2024, Boisson tore her ACL, putting her tennis career at a complete halt.

Because of that torn ACL just a week before her potential first Grand Slam tournament began, it prevented her from competing. At the time, she was ranked a career high of No. 152. Now, she’s become the biggest story at the French Open after her injury recovery and will be skyrocketing up the world rankings.

Before the 2025 French Open, Boisson started to get back into her rhythm at the ITF-level, winning a tournament. But even still, with the level of competition she’s faced at Roland-Garros, she’s had a shocking run and unique story.

“It’s incredible, no matter what, given what happened last year and all the difficult moments I went through,” Boisson said after advancing to the 2025 French Open semifinals, per ESPN.

Lois Boisson deodorant

Boisson has been in a big spotlight before, but for a very different reason. In April, at a WTA 250-level tournament in Rouen, France, Boisson’s opponent asked the umpire if she could tell Boisson to wear deodorant.

“She smells really bad,” Britain’s Harriet Dart said in a clip that went around social media. 

Boisson then posted on social media poking fun at the clip, using a photo of deodorant photoshopped into her hand. 

Dart later apologized for her comment about Boisson wearing deodorant, posting on Instagram: “I want to apologise for what I said on court today, it was a heat-of-the-moment comment that I truly regret. That’s not how I want to carry myself and I take full responsibility. I have a lot of respect for Lois and how she competed today. I’ll learn from this and move forward.”
