takes no extra time, and the results are visible before you leave

Kérastase Fusio-Dose is a professional in-salon hair treatment that combines a targeted Concentré with a Booster into a custom formula built for your specific hair. It is available exclusively through certified Kérastase salons. The treatment repairs damage, smooths the cuticle, and delivers visible results from the first application. No two formulas are the same.

A Fusio Dose works because it gets into the fiber, not just the surface. Kérastase's concentrated actives penetrate where standard conditioning products stop, addressing structural damage rather than coating over it.

Personalized from 36 targeted combinations, Fusio-Dose is not a single formula applied the same way to every client.

Before your specialist applies anything, they assess your hair: damage level, texture, scalp condition, and what you want out of today's visit. From there, they select the Concentré that addresses your primary concern and the Booster that handles the secondary one. Color-treated and frizz-prone gets a different formula than dry and structurally weak. That specificity is the point.

This is what separates a Fusio-Dose treatment at a certified salon from anything you buy off a shelf.

Most clients benefit from it. It's particularly worth adding if any of these apply:

• Color-treated or chemically processed hair that needs structural support
• Heat-damaged hair that has lost elasticity or shine
• Dry, brittle, or dehydrated strands
• Anyone wanting visible improvement before an event
• Healthy hair you want to maintain between head spa visits

If you are unsure whether it is the right add-on that day, your specialist will tell you. The scalp and strand assessment at every visit gives them what they need to make a real call on it.

Here's what happens to your hair in a single appointment:

• Damage repair and fiber rebuilding from within
• Cuticle smoothing for softer, shinier, more manageable hair
• Frizz reduction and improved texture
• Visible improvement before you leave the chair

For damaged or chemically processed hair, you notice it in how the hair moves and feels. For hair that is already in good shape, it keeps it there.

Your specialist applies it during the rinse as part of your head spa service or blowout, so nothing changes about your appointment. No extra booking, no added time.

If your hair would benefit from it that day, they will tell you. Every visit at The Head Spa includes a microscopic scalp-skin screen, so your specialist already has a clear picture of what your hair needs before they recommend anything.

The Fusio-Dose conversation usually comes up on its own, but you can always ask.
