The Exclusive Launch of ZEN Shampoo at 37 COSTCO Locations Across Japan

ZEN Shampoo Now Available at COSTCO

Oji Pharmaceutical Co., based in Shibuya, Tokyo, has launched its hair care brand, ZEN Shampoo, in exclusive packaging for COSTCO. The shampoo and conditioner set will be gradually available in all 37 COSTCO locations nationwide, following its success in online sales where it quickly sold out. ZEN Shampoo offers a hair care experience that turns daily bath time into a soothing ritual, ensuring cleanliness while maintaining moisture for light, manageable hair.

Unique Formulation Inspired by Skin Care

ZEN Shampoo employs a formulation philosophy inspired by skin care. This design gently cleans both the scalp and hair while preserving moisture, resulting in a light finish. This series has gained popularity among many customers, making it a perfect addition to their daily hair care routine.

Special Features of ZEN Shampoo

Designed specifically for those concerned about an oily scalp, this product eliminates excess sweat and sebum, leaving the hair fresh and invigorating. It features a refreshing green leaf scent reminiscent of traditional Japanese herbal ingredients, creating a pleasant atmosphere post-bath.

Moisturizing Care for Scalp

With ingredients like Niacinamide and Panthenol, ZEN Shampoo nourishes both the scalp and hair, creating a fresh sensation without overwhelming moisture. It's easy to incorporate into one's daily hair care practices.

Lightweight and Silky Finish

Its fine foam gently envelops the hair, resulting in an impressively light and smooth finish. It provides a sense of ease in handling the hair while avoiding heavy moisture.

Fragrance Profile: "This is the Scent of Balance"

The scent profile is based on Fresh Green Leaf with an aromatic depth inspired by traditional Japanese ingredients. It encapsulates a mix of freshness and tranquility, creating a pleasant bathing experience. The fragrance notes create a feeling as if you want to take a deep breath in a moment of serenity.
