FUSIO-DOSE The Fusio-Dose In-Salon Hair Routine
A highly personalized 4-step hair treatment protocol
using Fusio-Scrub and Fusio-Dose.

1. Diagnose
Request your in-salon diagnosis, so your hairdresser can assess your hair’s current condition.

2. CHOOSE YOUR MIX
Depending to your 1st hair need, the hairdresser selects a concentré. And depending to your hair desire, he/she chooses your booster.

3. Mix and spray
The hairdresser mixes and applies the Fusio-Dose concentré + booster formula targeting your concerns.

4. PROCEED TO BLOW DRY
Finish with a Thermique to protect your hair from heat before proceeding to blow dry.


Far more than the place to get your root touch-up or an occasional trim, book an appointment at your nearest Kérastase salon for a complimentary personalized hair diagnosis.
