K18 Biomimetic Longevity Hair + Scalp Serum — 3.04 oz nightly leave-in, reduces shedding

K18 FutureIQ Biomimetic Longevity Hair + Scalp Serum is a nightly, lightweight leave-in serum designed to support scalp health and help reduce shedding, slow early graying progression, and protect against signs of premature hair aging.

This serum pairs K18's MultiVital™ biomimetic approach with a water-based, non-greasy formula created for regular nightly use. Clinical testing of the MultiVital system showed earlier improvements in shedding, measurable density gains by month two, and notable hair-count and graying benefits by month three. The product is fragrance-free, vegan, and formulated to sit comfortably under existing routines, including color and chemical treatments.

How does this serum address shedding and scalp aging?

The serum targets multiple biological pathways linked to early hair aging rather than a single mechanism. Applied nightly as directed, it supports scalp resilience to create an environment less prone to shedding and aging signs over time.

• Multi-pathway MultiVital™ technology designed to influence factors that contribute to premature hair aging.
• Clinically observed reduction in shedding within the first month when used nightly.
• Water-based, lightweight texture prevents build-up and allows continuous overnight action.

What results can I expect and on what timeline?

Visible changes are gradual and based on consistent nightly use. Clinical testing reported reductions in shedding early, increases in hair density by month two, and cumulative hair-count and graying improvements by month three.

• Less shedding reported as early as the first month of nightly use.
• Increased hair density noted around month two with ongoing application.
• Measured hair-count gains and reduced early graying signs by month three in clinical testing.

How do I incorporate the serum into my hair care routine?

Use once each night on damp or dry scalp after cleansing steps for best continuity. Four droppers per application provide the recommended dose; the product is leave-in and does not rinse out, making it simple to layer under treatments or sleep with overnight.

• Apply 4 droppers filled to the line directly to the scalp nightly.
• Distribute evenly and massage in; do not rinse—one bottle lasts about one month.
• Recommended to follow K18 Detox Shampoo and Mask for a full scalp-to-ends program.

Is this safe for color-treated or chemically processed hair?

The formula is developed to be non-greasy and compatible with treated hair, so it can be used alongside color, lightening, and other chemical services. Its clean, fragrance-free composition minimizes added stress on hair while you sleep.

• Suitable for color-treated, chemically processed, and natural hair types.
• Free from sulfates, parabens, phthalates, and fragrances for gentle daily use.
• Vegan and cruelty-free formulation designed to sit lightly on the scalp.

Who this product is for: K18 FutureIQ Serum is aimed at people noticing early signs of scalp aging—such as increased shedding or premature graying—or anyone wanting to proactively support scalp health. It works for men and women across hair types, including color- or chemically-treated hair, and fits into nightly routines for those seeking a non-greasy, evidence-informed option to preserve hair longevity.
