70% fewer grey hairs in 3 months with the K18 Future IQ serum
Seventy percent fewer grey hairs in three months: that is the promise the Future IQ serum by K18 makes, backed by clinical data. A result that, if it holds over time, could radically transform the hair routine of millions of people tired of booking one colour appointment after another.
A simple evening ritual with real results
One of the standout qualities of the Future IQ serum is how easy it is to use. Every evening, simply apply four pipettes to the scalp, whether hair is dry or damp. K18 recommends dividing the head into four distinct zones: the centre parting, the two side partings, and the hairline at the roots, dedicating one pipette to each.
Once the product is distributed, a gentle massage is advised to help it absorb. This massage follows a specific path: start at the top of the forehead, work up toward the crown, then move down to the nape of the neck. Another welcome bonus: the serum is leave-in, which makes the step even more straightforward.
To make application easier, Sephora suggests tying hair into a loose ponytail before distributing the pipettes. This allows easier access to each section of the scalp and helps avoid missing any spots.
What the Future IQ serum contains and how it works
To develop this treatment, K18 created an exclusive complex called MultiVital™. This complex targets several mechanisms at once, which sets it apart from a standard hair care product. First, it incorporates a rich blend of antioxidants designed to nourish and care for the scalp.
The complex also acts on the process that anchors proteins at the hair root, which helps reduce hair loss. Finally, the formula contains biomimetic peptides: their role is to intervene directly in hair pigmentation, targeting the very mechanism responsible for grey hair appearing in the first place.
This triple simultaneous mode of action is at the heart of the Future IQ serum‘s promise. By working on scalp vitality, hair strength, and hair colour all at once, the product aims to tackle the problem at its source rather than simply masking it.
Clinical results and user reviews
After three months of use, the clinical study conducted by K18 delivers striking figures. 54% of participants reported that their scalp felt revitalised. They also observed 70% fewer grey hairs and up to 19,000 hairs retained.
- 54% of participants felt a revitalised scalp

Consumer reviews published on the Sephora website tell a similar story. Some users mention a noticeably slower progression of grey hair, while others describe it as a product that has changed their life. One customer is already on her fourth bottle, a level of loyalty that speaks volumes about the satisfaction it delivers.
Why this serum meets a genuine need
Grey hair is not just an aesthetic concern. For many people, it means a demanding upkeep routine: regular colour treatments, frequent touch-ups, and a significant investment of both time and money. This cycle can become exhausting, especially when ageing hair also loses vitality, breaks more easily, and grows back with difficulty.
This is precisely the context in which the K18 Future IQ serum makes so much sense. Rather than covering grey hair with colour, it aims to act upstream, on the biological mechanisms that cause it. The fact that the appearance of grey hair is partly genetic makes a solution that claims to measurably slow this process all the more valuable.
By continuing the treatment beyond the first three months, the effects can become even more significant, according to the brand. The Future IQ serum is therefore designed as a long-term care ritual, to be incorporated into an evening routine with no rinsing required and no extra time commitment.
