Consistency is key for the hair ecosystem to regain its natural balance. The Cair subscription supports you through this essential continuity, offering a routine designed to extend the benefits of your treatments and sustainably strengthen the health of your hair microbiome.
After 1 month, your hair feels shinier and lighter. It stays clean for longer. Lengths feel naturally smoother and softer.
After 3 months, your hair fibers are detoxified, your scalp is purified and regains its balance. Hair regrowth becomes stronger and faster.
Beyond that, your hair is sustainably freed from accumulated petrochemical residues and your scalp feels soothed.
The essential step for stronger hair and a revitalized scalp
The Strengthening Duo brings together the N.04 hairbrush and the La Bonne Brosse strengthening serum for a simple and effective ritual that stimulates the scalp and strengthens hair from the roots.
The vegan, detangling N.04 brush provides an invigorating massage thanks to its soft nylon bristles. It stimulates microcirculation, promotes hair growth and gently detangles all hair types.
The strengthening serum, rich in skincare actives and prebiotics, respects the scalp microbiome thanks to its alcohol free formula. It hydrates, rebalances the scalp and strengthens hair from the very first use.
A complementary duo for a healthy scalp and visibly stronger, more radiant hair.

How to use
How to use the strengthening serum and the massage brush
Before shampooing, apply the strengthening serum directly to the scalp to support long lasting hair vitality and strength. Thanks to its precision spray, distribute the treatment evenly over the roots by gently parting the hair. Then massage the scalp to activate microcirculation, help remove impurities and promote the absorption of active ingredients into the upper layers of the epidermis.
Leave on for ten to fifteen minutes, or extend the application overnight as part of an intensive one month treatment, one to two times per week. Rinse thoroughly and follow with your usual shampoo.
The massage brush ideally completes this ritual. Suitable for all hair types, including thick, curly, frizzy or sensitive hair. Use the brush on dry or slightly damp hair, after shampooing or treatments, for a revitalizing massage that stimulates the scalp and enhances the hair’s natural beauty. This gesture can be performed daily, in the morning or evening, according to your preference.

Reviews
Angenehmes Serum
"Das Serum lasst sich leicht anwenden. Es schäumt etwas beim Einreiben. Es riecht gut. Ich lasse es über Nacht wirken. Da ich es bisher nur 3 mal angewendet habe kann ich keine Langzeitwirkung beurteilen."
— Ana E. (5/5)
Un excellent soin pour fortifier les cheveux
"J’aime beaucoup ce sérum ! Il laisse mes cheveux plus doux, brillants et soignés. Sa texture est agréable et il ne laisse pas les cheveux gras. Une belle découverte que je recommande volontiers."
— Méhanya B. (5/5)

Routine Cair
"La routine est ultra complète, le packaging est très qualitatif et soigné, la sensorialité des produits est dingue (on retrouve l’odeur signature dans tous les soins). C’est simple, depuis que j’utilise les produits Cair (couplés à l’utilisation quotidienne de La Bonne Brosse), je remarque que mes cheveux sont beaucoup plus brillants et semblent en bien meilleure santé. La possibilité de commander des petits formats pour les voyages + les recharges pour ne pas « sur consommer » fait de cette marque un exemple en terme d’éthique. Bravo et merci les filles ✨"
— Jeanne R. (5/5)

"Enamorada de los productos! Todos! Los amooooooo"

The best serum ever
"I love the floral scent and after washing my hair, it feels silky soft."
— Andrea H. (5/5)
La baronne brosse 1
"Je l’adore je ne peux plus m’en passer à tel point que j’ai commandé la petite pour en avoir toujours une avec moi. J’ai les cheveux fin et long qui avait tendance à faire des queues de rat et c’est fini grâce à la bonne brosse. J’ai aussi plus de volume et ils regraissent moins vite. C’est devenu mon rituel matin et soir."
— Jenna T. (5/5)
