Roman K Salon proudly offers the Kérastase Fusio-Dose treatment, a highly personalized service that transforms your hair instantly. Launched by Kérastase in 2011 and enhanced in 2022 with advanced skincare activities, this treatment has stood the test of time due to its exceptional customization and immediate results.


Tailored to Your Hair's Specific Needs

The Fusio-Dose treatment begins with a professional hair diagnosis by our trained stylists. This allows us to determine your primary hair concerns. The treatment involves a unique blend of a Concentré, which targets your main hair concern, and a Booster, which is enriched with powerful skincare active ingredients to achieve your specific hair goals. With up to 30 different combinations available, the Fusio-Dose can address dual hair needs in one application, offering solutions such as 95% less breakage, 70% more shine, and 24-hour anti-frizz protection.

Quick and Effective Treatment Process

This tailor-made treatment is designed to be swift and effective. After the initial hair diagnosis, your stylist will mix the appropriate Concentré and Booster, applying it directly to your hair. The entire application process takes just about 5 minutes at the back bar, leaving you with re-energized, visibly healthier hair almost immediately.
