    • more to know

      Noticing shedding, graying, or scalp aging earlier than expected? You’re not alone—69% of people see earlier graying, and 66% notice shedding sooner than they anticipated. These can be signs of premature hair aging accelerated by stress, chemical services, your environment, or lifestyle.

      FutureIQ™ serum intervenes at the earliest biological markers of premature hair aging like shedding, graying + scalp aging. It works best for those with less than 30% gray and minimal to moderate hair shedding.

      Proprietary MultiVital™ technology's biomimetic peptides, root anchoring complex + advanced antioxidants synergistically activate together to help reduce the breakdown of root proteins that hold hair in place, support the signaling involved in melanin synthesis and transport, and amplify the follicle’s natural defenses against oxidative stress to help protect the scalp. As a result, the appearance of grays is delayed, shedding is reduced, and the scalp looks and feels healthy.

 your FutureIQ™ questions, answered
How is FutureIQ™ biomimetic hair longevity serum different from traditional anti-gray and hair growth serums?

Premature hair aging is a multifaceted problem caused by several biological mechanisms happening at once. Pigment cells are slowing down, follicle anchorage is weakening, and oxidative stress is accelerating it all. A single-target solution may only address one of these symptoms or temporarily mask the visible presentation of them. By targeting key biological pathways associated with visible signs of premature hair aging like oxidative stress, hair shedding, and hair graying with targeted multi-prong technology, FutureIQ™ serum addresses the full picture of what's actually driving the visible changes.

Does FutureIQ™ work for everyone?

FutureIQ™ is specifically designed for anyone experiencing signs of premature hair and scalp aging. It works best for those with less than 30% gray and minimal to moderate hair shedding.

Will it leave residue on my pillows or leave my hair greasy?

No, the product is lightweight and absorbs quickly. When used as directed, it should not leave residue on pillows or leave hair greasy.

Can this be used on a wet or dry scalp? Will there be a difference in results?

FutureIQ™ can be used on both wet and dry scalp. There is no difference in results if used wet versus dry.

Will FutureIQ affect silk presses, blowouts, or other non-chemically straightened styles?

As this is a water-based serum, it may revert hair textures that have been straightened. If this is a concern, spot treatment around hairline and edges is recommended vs full head application.

"K18 is known for its biology-first approach. Everyone knows that we repair hair fiber. But we've actually been doing scalp research for several years now, and that research is finally getting into the consumer's hands so we can fight premature aging at the root."

dr. rachael williams

senior scientist at K18 + expert in scalp and hair follicle biology

"As a board-certified dermatologist, I'm always looking for products that are backed by science and address the underlying causes of hair concerns rather than simply masking them. FutureIQ™ stands out because it takes a scalp-first approach while leveraging K18's peptide technology to support long-term hair and scalp health. I've been impressed by its focus on creating an environment that supports healthier-looking, fuller hair over time, while still being lightweight enough for everyday use."

dr. mina amin

board certified medical & cosmetic dermatologist

"Your scalp is skin. Full stop. It ages that same way, it responds to the same biological signals, and it has been completely ignored by the industry until now. FutureIQ™ brings the same preventative thinking to hair that we have always applied to the face. That is long overdue."

dr. Vali

twice board-certified cosmetic dermatologist + medical wellness and longevity expert + K18 ambassador

"As a dermatologist, I love that FutureIQ™ takes a longevity approach to hair by focusing on the scalp and hair follicle. It's designed to support healthier, fuller-looking hair while also addressing concerns like thinning, graying, and scalp aging."

Reviews Summary
Customers say this hair serum noticeably reduces shedding and promotes fuller, thicker-looking hair. Many reviewers mention new growth around the hairline and improved scalp health within weeks of consistent use. The lightweight, non-greasy formula absorbs quickly and fits easily into nightly routines. Common feedback includes softer, shinier hair and reduced flaking. Some users report less frequent graying, though results vary. A few note the high price point as a consideration, and consistency with daily application is emphasized as key to seeing benefits.

    L-O-V-E this stuff!!!

    This FutureIQ is absolutely amazing!!! My hair has never felt so good, and yes, it has turned back the time on my hair! Makes my hair feel like it did when I was waaaayyyy younger. It's easy to use and I don't ever want to be without it. I finally found something that actually works. And believe me, I have a graveyard of products in my bathroom cupboards of stuff that just doesn't do much. I want to tell all my friends about this - it's that good! Sometimes I'll even skip and day of washing it because it still looks so good - soft, manageable, shiny and amazing. That has NEVER happened before. I'm not sure what's in this but I am impressed with the results! 👍🥰

    So far so good.

    I absolutely love K18 products! After just 15 days of consistent use, I noticed a significant difference in the texture and overall health of my hair. Hair also growing faster..

    In terms of graying, still too early to have concrete feedback. But overall happy with the purchase.
