La Sana Launches Limited-Time 'Clear Empty Bottle Set for Shampoo & Treatment' Born from Customer Feedback on April 1, 2026 (Wednesday)

Yamasaki Co., Ltd., which operates "La Sana," the No. 1 domestic hair treatment counseling seaweed cosmetics brand (※1), will launch the 'La Sana Shampoo & Treatment Exclusive Clear Empty Bottle Set' for a limited time from April 1, 2026 (Wednesday) to May 31, 2026 (Sunday) via mail order and internet sales (※2). This product was developed in response to customer feedback requesting "an empty bottle that shows the refill pouch inside." ※1 2023 results, "Cosmetics Marketing Handbook 2024" for counseling (including mail order), as La Sana brand ※2 While supplies last 【Development Background】 La Sana values "co-creation" with its customers. As part of this initiative, we operate the fan community site "Lala La Sana." At 'Lala Meets in Tokyo,' the first offline event for "Lala La Sana" held on September 26, 2025, participating customers expressed a desire for "a bottle that clearly shows the design of the refill pouch." The existing 375ml/g shampoo and treatment empty bottles are milky white with a simple design, blending well with any bathroom interior. However, as they are common bottles for all La Sana series, there was a drawback in that customers could not fully enjoy the design of the refill pouches. In response to these customer voices, we have developed a shampoo and treatment exclusive empty bottle with a transparent body. This limited-edition bottle allows customers to enjoy their daily hair care, including the design of the refill. La Sana will continue to listen to customer feedback and aim to be a brand that grows together with its customers. 【Points】 ■ Transparent Empty Bottle Born from Customer Feedback 【NEW】 This product was born from customer feedback received at an event of "Lala La Sana," the fan community site that embodies La Sana's commitment to "co-creation" with its customers. ■ Enjoy the Refill Design! 【NEW】 La Sana's shampoo and treatment refill pouches come in a rich variety of designs. While these designs were hidden by conventional bottles, the transparent bottle allows customers to enjoy them directly. It also makes it easier to judge when to refill. ■ Easy Refilling with a Refillable Bottle System By simply attaching the shampoo and treatment refill pouch to the dedicated empty bottle, refilling can be done easily without pouring. This eliminates the stress of getting the bathroom or hands dirty during refilling. ■ Hygienic Use Down to the Last Drop When the pump draws up the product, the inside of the shampoo/treatment refill pouch becomes a vacuum, preventing the contents from coming into contact with water or outside air. This ensures hygienic use down to the last drop. 【Shampoo & Treatment Lineup】 ■ Damage Hair Care Series For those who desire manageable, shiny hair. Formulated with marine ingredients optimized for each item to care for daily damage from perms, coloring, UV rays, etc. Repairs damaged hair and fills it with moisture.
