Yamasaki Corporation (Headquarters: Hiroshima City, Representative Director & CEO: Hikaru Doi), which operates La Sana, the No. 1 hair treatment counseling seaweed cosmetics brand in Japan (※1), will be launching a limited-time new product, the 'La Sana Shampoo & Treatment Exclusive Clear Empty Bottle Set,' through mail order and the internet from Wednesday, April 1, 2026, to Sunday, May 31, 2026 (※2). This comes in response to customer requests for 'empty bottles that allow the refill pouches inside to be seen' and can be used across all La Sana series. ※1 Based on 2023 results, 'Cosmetics Marketing Yearbook 2024' counseling (including mail order), as the La Sana brand ※2 While supplies last ## 【Development Background】 La Sana values 'co-creation' with its customers. As part of this initiative, it operates the fan community website 'Lala La Sana.' At 'Lala Meets in Tokyo,' the first offline event for 'Lala La Sana' held on September 26, 2025, participating customers voiced a desire for 'bottles that clearly show the refill designs.' The existing 375ml/g shampoo and treatment exclusive empty bottles are milky white with a simple design, blending into any bathroom interior. However, as they are common bottles for all La Sana series, there was an aspect where the design of the refill pouches was not easily enjoyed. Therefore, in response to these customer voices, we have developed shampoo and treatment exclusive empty bottles with a transparent body. We are now launching these limited-edition bottles, designed to allow users to enjoy their daily hair care, including the refill designs. La Sana aims to continue growing as a brand that listens to customer feedback and evolves with its customers. ## 【Points】 * **Transparent empty bottles born from customer feedback 【NEW】** Born from feedback received at an event by 'Lala La Sana,' a fan community website that embodies La Sana's cherished 'co-creation' with customers. * **Enjoy refill designs! 【NEW】** La Sana's shampoo and treatment refill pouches come in a rich variety of designs for each series. While these designs were hidden in conventional bottles, transparent bottles now allow users to fully enjoy them. It also makes it easier to judge when it's time for a refill.
