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.

    Jury’s still out

    I have a bone to pick about the product design. Why make a huge bulky dropper that only fills 1/3 of the way and make the nightly dose 4 dropper fills? Clunky and annoying to use. Anyway, I have been using this product for about a month for hair loss. I have noticed some new baby hairs around my hair line but not in my other problem areas (e.g crown)… but might just be because I’ve been doing less slick backs. I don’t have any greys so can’t comment on that. Will keep trying for a few months but if I don’t see more improvement, it’s not worth the price.

    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.
