Hagiwara decided to retire from the entertainment industry to study English abroad in New Zealand following the disbandment of ℃-ute on June 12, 2017.
Hagiwara Mai was born on February 7, 1996 in Saitama, Japan.
Hagiwara continued her work within Hello! Project Kids, performing alongside Morning Musume at concerts as backup dancers.
In late 2004 Hagiwara took part in her first Hello! Project shuffle unit, H.P. All Stars, taking part alongside all the members of Hello! Project at the time. The shuffle unit released one single and became inactive by January 2005.
Hagiwara was assigned as a member of Hello! Project group ℃-ute alongside seven other Hello! Project Kids members. These eight members had been passed over when it came to the forming of Berryz Koubou, which had originally been formed to teach the Hello! Project Kids about being in a group by rotating the line-up amongst the kids. Originally ℃-ute was releasing songs on an indie label, but in 2007 they made their major debut.
Hagiwara Mai released four indie singles as a part of ℃-ute in preparation for their major debut in 2007. ℃-ute also released their first album, Cutie Queen VOL.1.
On February 21, ℃-ute released their debut single, "Sakura Chirari." On the first day in the Oricon charts it ranked third, a feat not even accomplished by Hello! Project's mother group Morning Musume (who had ranked 6th on their debut single). With their debut single, they became the youngest group (with the average age of 13) to rank in the top 10. Hagiwara provided minor vocals for their debut single.
Hagiwara also joined with Morning Musume's Kusumi Koharu to form a one-shot unit named Kira☆Pika. The group was formed to perform songs for the anime Kirarin☆Revolution, as both girls voiced characters in the series. They released their debut single on August 1.
Hagiwara Mai, along with four other members of ℃-ute and Berryz Koubou left the Hello! Project futsal team Gatas Brilhantes H.P.. The members left of their own violition due to feeling that they could not perform as high level players due to their level of ability.
On December 15, Hagiwara opened her first Ustream channel called Mai Desu ga... Nani ka?. In the show, Hagiwara invites various Hello! Project members to do activity with her such as talking and cooking.
On July 25, it was announced that Hagiwara, Yajima Maimi, Nakajima Saki and Berryz Koubou's Shimizu Saki, Sudo Maasa, Kumai Yurina and Sugaya Risako would be performing in an stage play titled CAT'S♥EYE based on a manga. The stage play ran from September 22 to September 30.
On March 2, at Forest For Rest ~SATOYAMA e Ikou~ SATOYAMA movement in YOKOHAMA, Hagiwara was announced a member of the new SATOUMI movement unit, Plumeria (later renamed HI-FIN), along with fellow ℃-ute member Nakajima Saki, S/mileage's Fukuda Kanon, and Morning Musume's Ishida Ayumi and Ikuta Erina.
On July 3, it was announced Hagiwara would be releasing her second photobook called Mai2 on August 5.
On January 17, the official site of Hello! Project announced that Hagiwara had a high fever. She was immediately taken to the hospital where she was diagnosed with influenza. For this reason she was not present for the handshake event scheduled that day and she was also not present in the Hello! Project 2014 WINTER concert tour on January 18 and 19.
From February 5 to 7, Hagiwara, Yajima Maimi, and Nakajima Saki celebrated their birthdays in a joint fanclub event called Yajima Maimi・Nakajima Saki・Hagiwara Mai 2014 Birthday Event, which featured six performances in Saitama, Osaka, and Tokyo.
On February 26, Hagiwara featured in a special book called "Graduation -High school graduation- 2014" with four other idols graduating high school that Spring. It contained photos and interviews.
On February 5, 6, and 8, Hagiwara, Yajima Maimi, and Nakajima Saki celebrated their birthdays in a joint fanclub event called ℃-ute Yajima Maimi・Nakajima Saki・Hagiwara Mai Birthday Event 2015, featuring four performances in Tokyo.
On February 7, Hagiwara and Yajima Maimi celebrated their birthdays in a joint fanclub event called ℃-ute Yajima Maimi & Hagiwara Mai Birthday Event 2016, featuring three performances in Tokyo.
During the last show of ℃-ute's 11th anniversary event on June 11, Hagiwara made an apology after Shukan Bunshun reported and published photos of her walking with a man on the tabloid's web program back in April. She admitted the man was a friend and did not think fans would misunderstand, and even considered quitting in order to take responsibility for the problems it caused. However, she spoke to the other ℃-ute members who wanted to continue to work hard together, and Hagiwara stated she would slowly do her best to regain fans' trust and support. Group leader Yajima also made a blog post with similar statements.
On February 7, Hagiwara and Yajima Maimi celebrated their birthdays in a joint fanclub event called ℃-ute Yajima Maimi & Hagiwara Mai Birthday Event 2017, featuring two performances in Tokyo.
On February 7, Hagiwara showed her face for the first time since ℃-ute disbanded (between this time, other former ℃-ute members had her face covered in photos) by opening an Instagram account on her 22nd birthday. She announced she was currently studying abroad and was working hard on a career path that is not part of the entertainment world.
On May 31, Hagiwara was announced as the design producer of &IDOL, a committee of former idols led by former Idoling!!! member Ito Yuna who aim to collaborate with various industries to develop a new market with a business concept that is centered on idols (active and retired) and would help grow the economy. Their first project was a beach café named SUMMER&IDOL which was open at Yuigahama in Kamakura Prefecture from July 2 to August 31.
On July 2, she announced that she had designed an original T-shirt for the SUMMER&IDOL project under the brand name With Mii which she plans to start as an official company. She established the company on September 13 and opened an official website for it.
Hagiwara has an older sister who auditioned for Hello! Project Kids alongside Mai, but failed to pass.
She also has a pet dog named Chip-kun.
On October 3, 2016, Hagiwara's grandmother passed away. 
Hagiwara's given name, Mai, means "dance" (舞; mai). "Mai" was the name of a heroine in a manga her mother was reading, and since the character was a very beautiful girl, she was named Mai.
