Fusio-Dose is Kérastase's personalised salon treatment, mixed fresh in the salon. The stylist first makes a diagnosis and chooses a Concentré for the main hair need, such as nourishment, colour care or repair. The client adds a Booster for a second need, for example shine, anti-frizz or extra nourishment. Together they offer more than thirty combinations. The formulas are inspired by skincare and contain a higher concentration of active ingredients than the previous Fusio-Dose. The treatment itself is simple: Concentré and Booster are mixed, applied to the lengths and ends and rinsed out again. From shine to repair to volume: the mix changes with what the hair needs at that moment, composed anew at every wash. That's why it isn't a standard course, but a treatment that differs for every client.
No two heads of hair are the same, so why should the treatment be?
Kérastase Chronologiste Overnight Youth Serum — repair while you sleep
A night serum that skips the rinse: Pro-Xylane and algae extract keep working all night while the hair is left completely undisturbed.
Kérastase Elixir Ultime — oil that softens hair after summer
Sun and salt water leave hair dry and frizzy after summer. Elixir Ultime, with wild camellia oil, softens lengths without weighing them down.
Chronologiste — the ritual for her and her scalp
Chronologiste isn't just another wash — it's a moment of indulgence that calms the scalp and nourishes hair from root to tip.
