What Is a Kérastase Fusio-Dose?
Fusio-Dose is a customized Kérastase in-salon treatment that combines a booster and a dose, tailored to your hair’s specific needs. Your stylist diagnoses your hair and selects the appropriate combination from a range of boosters (targeting concerns like damage, dullness, or sensitivity) and doses (addressing hair type like fine, medium, or thick).
The treatment is applied at the basin in approximately 15 minutes, making it ideal as an add-on to any service. It does not require a long processing time, and the results are immediate — hair feels softer, looks shinier, and is more manageable right away.
What Is a Traditional Hair Mask?
A traditional hair mask is a deep-conditioning treatment applied to clean, damp hair and left on for a longer processing time — typically 10 to 20 minutes — before rinsing. Masks contain higher concentrations of conditioning ingredients than daily conditioners and are designed to penetrate the hair shaft for deeper hydration and repair.
Hair masks can be used at home or in the salon. Professional masks, like the Kérastase Indulgent Masque, use premium ingredients and are applied with professional techniques for a more intensive result than at-home versions.
Key Differences
The primary difference is customization. A Fusio-Dose is diagnosed and mixed for your hair’s specific needs at the moment of treatment. A hair mask is a pre-formulated product chosen based on your hair type, but it is not customized to the same degree.
Application time also differs. A Fusio-Dose is applied in about 15 minutes at the basin. A hair mask requires 10 to 20 minutes of processing time. Both can be added to a salon appointment, but the Fusio-Dose is faster.

Which Is Right for You?
If you want a quick, targeted treatment that addresses a specific concern — like dullness, damage, or scalp sensitivity — a Fusio-Dose is an excellent choice. It is ideal as an add-on to a haircut, color, or blow-dry appointment.
If your hair needs deep, intensive hydration — for example, very dry, color-treated, or sun-damaged hair — a professional hair mask like the Kérastase Indulgent Masque provides more thorough conditioning. Many clients use both: a Fusio-Dose at each salon visit and a mask weekly at home.
Using Both Together
Fusio-Dose and hair masks are complementary, not competing. A Fusio-Dose at the salon provides a targeted, professional-grade boost, while a weekly mask at home maintains hydration between appointments. Your stylist can recommend the right Kérastase products for at-home use.
For Miami clients, this combination is particularly effective because sun, humidity, and saltwater can deplete moisture rapidly. Regular professional and at-home conditioning helps maintain hair health in a challenging climate.
Cost Comparison
A Kérastase Ampoule Treatment is $50, and the Kérastase Mask Treatment is $70. Both are professional in-salon treatments. At-home masks vary in cost depending on the product. Your stylist can recommend the most cost-effective combination for your needs.
