NatureLab Appoints Fuka Koshiba as Brand Ambassador for 'Diane Perfect Beauty', Launches 'Silky Shine' Series and New Commercials

NatureLab Co., Ltd. (HQ: Shibuya-ku, Tokyo) is launching new commercials for its 'Diane Perfect Beauty' hair care series, featuring brand ambassador Fuka Koshiba. The new dry shampoo commercial, 'Shu-tte Shite Ikimasho (Let's Give it a Spray),' will air starting May 20, 2026, and the new brand commercial, 'Watashi no Shinsho ga, Hajimaru (My New Chapter Begins),' will start airing on TV and digital platforms on June 1, 2026.

The brand's new commercial depicts a positive woman who embraces her work and personal life to the fullest, portrayed by Fuka Koshiba.

The 'Silky Shine' series, set to launch on June 1, is the first hair care line in Japan to adopt the 'LOCKSCENT™ Technology,' which traps fragrance within the hair. This allows fragrance components to remain inside the hair shaft, ensuring long-lasting scent. The 'Silky Shine Formula' also repairs damaged hair, leading to silk-like shine and a smooth texture.

Since its launch in March 2019, the Diane dry shampoo series has been the number one selling brand for six consecutive years.
