The "Ideal Series," a hair care brand by hair salon GARDEN, will be releasing a hair styling product in collaboration with Isetan on March 5th. It will be sold in limited quantities in the hair care section on the first floor of the main building of Isetan Shinjuku. Two types are available: "Lilly," for soft, fine hair, and "Kelly," for coarse, thick hair (both 70g/2,415 yen). The cream-type formula reduces the stickiness typical of styling products, making it easy to spread by hand and preventing uneven application. Its moisturizing ingredients also provide hair care benefits. The container also features Isetan's original "Macmillan/Isetan" design. Development of this product began with a collaboration between a popular stylist from GARDEN and the Isetan buyer team, in response to consumer feedback that "I don't know which styling products to choose and can't use them properly." It was created based on a professional perspective that emphasizes the importance of choosing styling products based on "hair type" rather than "desired hairstyle."

Lily is a slightly looser cream type that creates a natural finish and soft volume. Kelly has a firmer texture that makes hair stand up, creating a stylish, three-dimensional nuance. The scent is the same damask rose and bergamot as the Ideal series hair cream "LALA".
