We all have days when our hair just isn’t behaving. Whether it’s feeling dry, dull, lacking volume or just not quite itself, sometimes your locks need a little extra love. That’s exactly where Kérastase Fusio-Dose comes in — and we are absolutely obsessed with it here at Julian Holland Hair @ Hesslewood.
So what exactly is Fusio-Dose?
Fusio-Dose is a liquid care technology designed for instant hair transformation. It’s an exclusive Kérastase service, only available in salon — consisting of a custom-blended mix of a Concentré and a Booster, making it the ultimate quick-fix problem solver for all hair types. Kerastase
What makes it truly special is that no two treatments are the same. Every single formula is freshly blended just for you, based on what your hair needs on that particular day.
How does it work?
When you come in for your appointment, your stylist will begin with a hair diagnosis — taking a close look at the condition of your hair and talking through your concerns and goals. Your stylist will perform a detailed professional diagnosis to define your main hair need and pick the right Concentré, then discuss your hair goals to pick the right Booster. Kérastase
The Concentré addresses your primary hair concern, with options including Resistance with Ceramides for breakage, Nutritive with Niacinamide for dryness, Genesis with Collagen Peptides for volume, and Chroma Absolu for colour-treated hair. This is then combined with a Booster to target your secondary concern — whether that’s shine, reconstruction, frizz control, or nourishment. Kérastase
The result? Up to 30 possible combinations, all designed to instantly and lastingly transform the hair. Kérastase
Why is it different to a regular treatment?
This isn’t your standard conditioning mask. Fusio-Dose molecules are up to 100 times smaller than a traditional haircare product, and it is supplemented with skincare actives Kerastase — meaning it gets to work deep within the hair fibre rather than just sitting on the surface.
Think of it as a “hair reset” tailored just for you — all in under 15 minutes. KérastaseIt can be added on to any appointment, meaning you don’t need to set aside extra time in your day to see a real difference.
Who is it for?
The honest answer is — everyone. If your hair feels dry, dull, or damaged due to heat styling, colour treatments, or environmental factors, Fusio-Dose can help. It’s also an excellent option for those looking to maintain healthy, vibrant hair throughout the year. Kérastase
It works beautifully alongside colour services too — particularly after a toning or colouring treatment to lock in vibrancy and restore condition.
How often should I have it?
Every salon visit! Your stylist will diagnose your hair and create a freshly-mixed formula that specifically targets your current hair concerns, and will recommend and adapt the formula each time to suit your hair needs as they evolve. Kerastase
Because your hair changes with the seasons, your lifestyle and the services you have, the beauty of Fusio-Dose is that it evolves with you.
