A Fresh Approach to Hair Care for Adult Women
Set to hit shelves and online stores starting February 3, 2026, the KC Hair Serum offers a fresh approach to tackling common hair concerns like dryness and lack of elasticity, which often become more prominent with age. This innovative product directly delivers the hair’s primary components, keratin and collagen, in a convenient spray format.
The development of KC Hair Serum stems from extensive research conducted by Willumina, targeting women aged 30 to 70. The findings revealed a significant appeal for ingredients like collagen (64.3%) and keratin (nearly 40% among women in their 60s and 70s) when it comes to hair care. However, the survey also highlighted a major pain point: the inconvenience and greasy residue associated with traditional oil and milk-based hair products. This insight paved the way for a product that combines potent restorative ingredients with a user-friendly, non-greasy application.
Unveiling the KC Hair Serum: Key Features
The “KC Hair Serum” comes in a 30mL bottle, with an official online shop reference price of 1,980 yen (tax included). Its core strength lies in its ability to directly replenish keratin and collagen, the very building blocks of healthy hair. Keratin, making up 70-80% of hair, is crucial for repairing damage and restoring vitality. The serum features two types of keratin: film-forming keratin that coats the hair surface for protection, and penetrating keratin that works deep within to repair.
Alongside keratin, the serum incorporates moisturizing collagen to provide a smooth, cohesive finish, addressing issues of poor texture and manageability. The formula boasts 99% beauty essence ingredients, is unscented, uncolored, mineral oil-free, and alcohol-free, ensuring a gentle yet effective treatment. Applying it is a breeze: simply spray an appropriate amount (around 4-5 pumps for short hair) onto towel-dried hair from 5-10cm away, then brush it through before blow-drying. This simple routine helps achieve hair that feels soft, smooth, and full of bounce, from root to tip.
As one might imagine, the shift from a ‘sticky’ routine to a ‘spray-and-go’ method is a game-changer. “We heard the calls for effective, yet effortless solutions,” a Willumina representative shared, “and we believe the KC Hair Serum delivers exactly that – essential nourishment for age-defying hair, without compromise.”
