Fortifying hair serum

Hair serum has become an essential step in maintaining healthy hair. A truly targeted treatment, it is applied directly to the hair follicle, where the quality of the hair fibre is formed. An unbalanced scalp can lead to weakened, dull and fragile hair. Treating the scalp with precision is the foundation for healthy growth and long-lasting strength.

Concentrated in high-performance active ingredients, the hair serum acts directly on the scalp ecosystem to optimise its biological functions. Enriched with prebiotics, it helps rebalance the scalp microbiome, stimulates microcirculation and creates the ideal conditions for stronger, denser and healthier-looking hair growth.

At Cair, we have formulated a serum designed for maximum efficacy and a flawless application experience: an ultra-lightweight texture, alcohol-free, non-greasy and residue-free, that instantly melts into the scalp without drying it out. Leave-in and easy to incorporate into a daily routine, it helps rebalance the scalp over time and visibly enhances hair density, strength and quality.

All about our fortifying serum

Your scalp is where the health and beauty of your hair is built.

Our detoxifying and strengthening hair serum, exceptionally rich in cutting-edge skincare active ingredients with proven action, is designed to stimulate the vitality of your scalp, redensify your hair and give it health and shine.

Alcohol-free and enriched with pre-biome, our strengthening hair serum respects the microbiota and promotes a rebalanced hair ecosystem. To promote the vital longevity of your hair, we recommend applying your strengthening serum before each shampoo. As a one-month intensive treatment, leave it on overnight 1 to 2 times per week.

How do I use my mask and serum?
+

It's perfectly possible to use your mask and serum at the same time, as these two products don't target the same hair problems.

Before shampooing, we recommend applying your serum to your roots to detoxify your scalp and your hyaluronic acid hair mask to your ends and lengths to repair damaged hair fibers.

Apply the serum directly to the hair roots and saturate the entire scalp using the directional spray, lifting the strands.

Serum, Mask or Oil: Complementary Rituals for Sublime Hair

The Fortifying Serum is applied directly to the scalp before shampooing. Leave it on for 15 minutes or overnight for optimal effectiveness, then rinse thoroughly before washing your hair. It can be used in synergy with the mask for a complete action. A true concentrate of exceptional active ingredients, it detoxifies and strengthens the hair fiber, stimulates scalp vitality, redensifies the hair, and reveals its full health and shine.

The Hair Mask is used before shampooing. A true repairing treatment, it deeply nourishes the hair, regenerates it, and restores strength and suppleness. By integrating it into your routine, you give your hair a moment of deep repair, ideal for reviving vitality from within.

The Protective Oil, on the other hand, is applied after shampooing, on dry or damp hair, as a finishing touch. It acts as a protective shield, enveloping the fiber to guard against external aggressors such as UV rays and dryness. Thanks to this, your hair stays strong and radiant throughout the day. It is the perfect ally for exposed hair.

In summary: the serum fortifies and detoxifies, the mask repairs, and the oil protects and enhances. Complementary rituals, working together to keep your hair healthy and beautiful over time.
