DISCOVER THE 6 CONCENTRÉS & 5 BOOSTERS OF FUSIO-DOSE
UP TO 30 DIFFERENT MIXES POSSIBLE
What Is Fusio-Dose?
Fusio-Dose is a professional-only, in-salon treatment system developed by Kérastase — the global leader in luxury hair care.
It’s powered by a simple but powerful idea: that your hair’s needs change from day to day, season to season, and service to service.
Each Fusio-Dose treatment is a custom-blended mix of two concentrated formulas:
Concentré: Your stylist’s chosen base formula, targeting your primary hair concern (like dryness, damage, or frizz).
Booster: A potent second formula infused with skincare-grade actives that deliver your desired end result — shine, strength, volume, or color protection.
Together, these two components create over 30 possible combinations, allowing your stylist to tailor the treatment exactly to your hair type, texture, and goals.
Think of it as a bespoke special treat for your hair — crafted in seconds, designed to deliver immediate results that last.
During your appointment, your stylist will take a close look at your hair’s texture, porosity, and condition to determine what it needs most.
From there:
Your stylist selects a Concentré to treat your main concern.
They add a Booster, chosen to amplify the result you want — like frizz control, shine, or strength.
The blend is freshly mixed in front of you, then evenly applied to your hair at the shampoo bowl.
After just five minutes, your hair is noticeably softer, smoother, and more radiant — no downtime, no heavy feel.
Fusio-Dose is the perfect add-on to any color, cut, or blowout, instantly enhancing your results and extending your salon-fresh shine.
The Fusio-Dose experience starts with a personalized diagnosis by your stylist.

Why Guests Love Fusio-Dose
This is not your average “deep conditioner.” Each Fusio-Dose treatment is powered by skincare-inspired ingredients like amino acids, ceramides, and nourishing oils that work deep within the hair fiber.
You’ll notice the difference right away:
Hair feels healthier, softer, and easier to manage.
Frizz is reduced and shine is amplified.
Treatments address multiple concerns at once (for example, dryness and color fading).
Results last through multiple washes — without weighing your hair down.
Fusio-Dose for Curly & Textured Hair
At Dwell, we know curls. From waves to coils, every curl pattern comes with its own set of needs — and that’s where Fusio-Dose truly shines.
Curly and coily hair often struggles with dryness, frizz, or loss of definition.
Traditional masks can feel too heavy, but Fusio-Dose delivers lightweight, deep hydration and strength without sacrificing bounce.
Our top curl-friendly combination?
Concentré Curl Manifesto – Infused with glycerin to hydrate and fortify curls for soft, defined texture with natural volume and reduced frizz.
Booster Anti-Frizz – Smooths and softens with polypeptides to make detangling easier and curls more touchable.
Or, for color-treated curls, Booster Brilliance – With lactic acid to preserve vibrancy and add luminous shine.
This blend enhances the natural beauty of your curls — leaving them hydrated, defined, and full of life.
Pro Tip: Fusio-Dose pairs beautifully with our KurlPro services, amplifying definition and nourishment while keeping your natural texture healthy between appointments.
What to Expect During Your Appointment
The best part? Fusio-Dose only takes about 5–10 minutes and is done right at the shampoo bowl. There’s no processing time — just an instant refresh for your hair.
You can add it to:
Any color or blonding service to boost strength and shine.
A haircut or blowout for smoothness and softness.
Or even on its own as a quick, luxurious pick-me-up.
Healthy Hair, Personalized Care
We love that Fusio-Dose fits perfectly into what we believe in most: care that’s personal, thoughtful, and transformative.
Whether your hair needs a post-summer recovery, a pre-holiday boost, or a regular dose of shine, this treatment delivers visible results that last — tailored completely to you.
