Benefits
1 - Fortifying serum, the first step in your hair routine
The first step in your Cair hair routine is the fortifying serum which must be applied directly on your hair roots. Made with 99% natural ingredients, such as rice water, it fully respects the microbiota : it soothes and revitalizes the scalp. The hyaluronic acid present in this natural hair care product helps retain more water. As a result, your hair is deeply moisturized and denser. Finally, thanks to its pre-biome complex, this natural hair care product is particularly effective against hair loss.
Its travel size allows for around 10 uses - 20 ML.
2 - Cair hyaluronic acid shampoo: your best ally for moisturizing your hair
This sulfate- and silicone-free shampoo gently cleanses and coats your hair. Its active waters (rice water, bamboo water, grape water and fermented raspberry water) moisturize, soothe, nourish and strengthen your hair. Its natural formula also contains hyaluronic acid, which absorbs and retains water in the hair fiber, keeping hair hydrated even in very dry environments.
Its travel size allows 3 to 5 uses - 30 ML.
3 - Detangling mist with 98% natural ingredients
This natural hair care product enriched with skincare active ingredients detangles, coats and adds volume to your hair. Active waters such as rice water strengthen brittle hair while providing deep hydration. This detangling mist also helps protect your hair fiber from external aggressors such as pollution and UV rays, thanks to its slightly acidic pH and its concentration of antioxidant plant nutrients. The scales of your hair are thus tightened and cared for: your hair is shiny and healthy.
Its travel size allows for around 10 uses - 20 ML.
How to use
How to do the Cair hair routine ?
1 - Before shampooing, apply Cair Fortifying Serum to your hair roots. Massage the product into your scalp. Leave in for 10 to 15 minutes, then rinse with clean water.

- Thin or short hair: 6 to 8 sprays

- Very damaged or dry hair: 15 to 17 sprays
Finally, brush your hair to detangle and style it, using your Bonne Brosse.
