SixTONES' Shintaro Morimoto is the new face of Retispa, a retinol-based hair care line. The group member was announced as the brand's ambassador at a press event in Tokyo on June 18, where he debuted the new "Try Retispa" TV commercial.

In the spot, Morimoto plays a fairy defending Retispa products from being returned to store shelves. He pitches the brand's key features—including its capsule-form retinol that conditions the scalp and leaves hair smooth—before delivering the catchphrase "Retispa shiyou" (Let's try Retispa).

Moremoto was selected for his approachable personality and sense of humor, qualities that align with Retispa's brand identity. At the press conference, he appeared in an orange jacket and pants matching his on-screen fairy outfit, joking that he wanted to clarify he wasn't the other famous personality known for similar roles.

When asked about his casting, Morimoto said he wanted to properly convey the brand's appeal. He reflected on the filming experience with self-deprecating humor, noting that despite being one of SixTONES' taller members, playing a tiny fairy character was surprisingly charming. He also revealed the physical demands of the role, admitting the clinging pose was exhausting—a challenge he hadn't faced since climbing trees as a kid.

Moremoto shared genuine praise for the product, explaining how Retispa helped tame his naturally thick, voluminous hair and improved texture. He highlighted the non-foaming formula's effectiveness, noting his initial concern about whether it was actually cleansing before experiencing the satisfying results. He also mentioned that SixTONES members benefit from thorough hair care due to stage pyrotechnics and special effects during performances, which can leave residue on their hair.

The brand is launching a campaign on July 1 offering Retispa purchasers a chance to win a "clinging charm" figurine modeled after Morimoto's fairy pose. He expressed enthusiasm about fans potentially spotting the charm around town, joking he'd approach anyone wearing it to say the commercial's tagline.

The new commercial is 15 seconds and airs now.
