At Headmasters, we believe that great hair starts with great care – and we don’t just mean the colour, the cut, or the finish. We mean what happens underneath all of that. The health of your scalp. The condition of each strand. The foundations that make every style work harder and last longer.
We’re proud to offer one of the most comprehensive treatment menus in the industry – because we know that no two heads of hair are the same. But today, we want to shine a light on one of our newest additions: the Kérastase Fusio Dose + Serum. A treatment so good, it’s already got our clients a little bit obsessed.
What Exactly Is the Kérastase Fusio Dose + Serum?
Think of it like a bespoke skincare routine – but for your hair. The Kérastase Fusio Dose is a multi-stage, personalised in-salon treatment that combines targeted boosters with a customised serum, working from the scalp right through to the ends to address your hair’s specific needs.
There’s no one-size-fits-all formula here. Your stylist will assess your hair and select the exact combination of actives that your hair is asking for – whether that’s strengthening, smoothing, rebalancing, or restoring.
And the best part? The results are instant. You’ll feel the difference before you’ve even left the chair.
Our Creative Director Clare sums it up beautifully:
“It really is a range that covers all your hair and scalp needs – just like skincare, this is a bespoke care routine service. And it’s something that isn’t time consuming, unlike many hair-care regimes – with both instant and long-term results.” – Clare, Creative Director
Creative Ambassador Danielle adds:
“It’s perfect for colour clients, especially after a global application, as it allows you to target the scalp with treatments tailored to specific needs or to help rebalance it. At the same time, the booster works through the lengths and ends to address additional hair concerns – making the whole service completely bespoke to each client’s individual needs.” – Danielle, Creative Ambassador
The Results – In Our Clients’ Own Words
We recently invited a group of clients with completely different hair types and concerns to try the Fusio Dose + Serum for themselves. Different ages, different hair, different frustrations – and every single one of them left with the same look on their face.
Here’s what they had to say:
“Weightless! As someone with thicker hair, I always find my hair gets weighed down – and this is probably one of the first times I’ve had something done to my hair and it doesn’t feel like I can feel it. Voluminous and clean – it feels squeaky clean, and nourished.” –Freya, 20s
Hair concern: Frizz, dryness and heat damage
“So soft and silky! I’ve not got the worst hair struggles, but I think even if you have healthy hair you can still benefit from a treatment like this.” – Sasha, 20s
Hair concern: Fine, flat hair lacking volume
“My hair feels like I don’t even have hair on my head – it feels so light and fluffy, like a cloud, and it’s got a nice shine. Instant results. Voluminous, healthy and happy – if you have irritated hair, this is great!” – MonaLisa, 30s
Hair concern: Scalp irritation and shedding
“I’ve never had so much volume – it’s got so much bounce, it’s got movement in it. I’m pre-menopausal and lots of women at my age struggle with hair getting finer and less of it. This treatment will really help, and it makes you feel good.” – Sabine, 50s
Hair concern: Fine hair lacking volume and style retention
For Every Hair Type.
What we love most about the Fusio Dose + Serum is just how universal it is. From a client in their 20s dealing with heat damage and frizz, to someone in their 50s navigating hormonal hair changes – this treatment meets your hair exactly where it is. Bespoke doesn’t mean complicated. It just means it works for you.
And if your concern is more about scalp health specifically – think buildup, sensitivity, or thinning – don’t worry, we’ve got that covered too. Our wider treatment menu includes options tailored to scalp-focused concerns, including our brilliant Deep Cleanse and Exfoliate Treatment.
“It was a game changer. I did not know how much I needed it. My hair has never felt like this before! It felt like a deep cleanse with hydration. I’m really happy and would do it again.” – Hamzah, 20s
Hair concern: Frizz, scalp buildup and loss of natural shine
