K18 FutureIQ is a 3.04 oz leave-in scalp and hair serum built around the brand's biomimetic peptide approach, extended from the hair shaft to the scalp itself. It is applied to a clean scalp and left in, aimed at reducing shedding and supporting the follicle environment rather than conditioning the ends. The texture is lightweight and non-greasy so it does not weigh down fine hair or require a second wash. This is a long-horizon product where results are measured over months, not a same-day styling change, and the price puts it firmly in the salon-brand tier. Best fit: anyone already using K18 mask who wants a scalp step, and people watching increased shedding who want a topical rather than an oral supplement.
Pros
- Targets the scalp and follicle rather than only repairing the hair shaft
- Lightweight leave-in texture that does not leave fine hair greasy or need rinsing
- From the brand that made bond repair mainstream, so the peptide science is its actual specialty
- One 3.04 oz bottle lasts a long time at a few pumps per application
Cons
- At $120 it is a real commitment, and scalp serums take months before any change is visible
Frequently asked questions
Do I rinse it out?
No, it is a leave-in. Apply to a clean, damp or dry scalp and leave it.
How long until I see results?
Scalp and follicle products work on the hair growth cycle, so expect to use it consistently for at least three months before judging.
Will it make my hair greasy?
The texture is lightweight and designed not to weigh hair down, which is a common failure point for scalp oils. It is a serum, not an oil.
Can I use it with the K18 leave-in mask?
Yes, they target different areas. The mask treats the hair shaft, this treats the scalp, so they layer in the same routine.
