KERASTASE Discipline Fluidissime Anti-Frizz Heat Protectant Spray 150ml

KERASTASE Discipline Spray Fluidissime 150ml is a lightweight anti-frizz and heat-protectant styling spray for unruly, frizz-prone hair. It helps smooth the hair fibre, improve manageability and provide up to 72 hours of anti-frizz protection, while its thermo-protective properties prepare hair for blow-drying and heat styling.

Unlike richer anti-frizz creams or oils, Fluidissime is designed to leave hair soft, fluid and shiny with a weightless finish, making it especially useful for fine-to-normal unruly hair.

72H anti-frizz protection – Helps control frizz and maintain smoother-looking hair for up to 72 hours.

Heat protection – Thermo-protective ingredients help protect the hair during heat styling.

Faster blow-drying – Helps improve manageability so hair is easier and quicker to style.

Lightweight smoothing – Controls frizz without leaving hair feeling heavy.

Softness & shine – Leaves hair smoother, more supple and visibly shinier.

What Is It?

KERASTASE Discipline Fluidissime Anti-Frizz Heat Protectant Spray 150ml is a lightweight leave-in styling treatment designed to make unruly and frizz-prone hair smoother, softer and easier to manage.

KERASTASE describes Spray Fluidissime as restoring the hair fibre's homogeneity while coating the fibre to improve manageability and provide anti-frizz protection.

Its role in the Discipline routine is:

Detangle → Smooth → Protect from Heat → Control Frizz → Improve Blow-Dry → Add Shine

The major advantage is the weightless finish.

For someone who wants anti-frizz control but finds creams and oils too heavy, Fluidissime gives us a much lighter alternative.

Fluidissime vs Kératine Thermique

Both are Discipline leave-in heat-protective products, but I would position them differently.

Fluidissime → Lightweight spray for anti-frizz control, manageability and easier blow-drying. Particularly good for fine-to-normal unruly hair.

Kératine Thermique → Smoothing blow-dry milk/cream with a richer texture for unruly hair needing stronger taming and smoothing.

KERASTASE describes Kératine Thermique as a heat-protecting blow-dry milk, while Fluidissime is its lightweight anti-frizz spray.
