Daiichi Sankyo Healthcare Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President: Takahiro Uchida; hereinafter "the Company") will launch a new cosmetic product, "Minon Scalp Moisturizing Lotion," on September 17, 2026 (Thu). This product is developed under Minon, a skincare brand dedicated to sensitive skin, and aims to provide moisturizing care specifically for sensitive scalps. The scalp tends to have high sebum but low moisture content, making it prone to barrier dysfunction due to over-washing or external irritants, which can lead to recurring issues such as dryness and itching. While Minon has previously supported consumers' hair care routines through the concept of "moisturizing cleansing," the launch of "Minon Scalp Moisturizing Lotion" introduces a new habit of directly moisturizing the scalp—"scalp moisturizing care." "Minon Scalp Moisturizing Lotion" is a moisturizer formulated with a balanced blend of moisturizing ingredients (*1) and emollient ingredients (*2), delivering hydration without a sticky or greasy feel. Packaged in a nozzle-type container, it is designed for direct application to the scalp, allowing targeted use on areas prone to dryness. Launched as a skincare brand focused on the skin's barrier function, Minon has earned long-standing consumer trust. Moving forward, the Company will continue to address the concerns of sensitive skin and contribute to improving quality of life (QOL). 1.
