Radiance Duo: La Bonne Brosse Pink October and the Leave-in Beauty Cream

A commitment at the heart of Pink October

For the second year, La Bonne Brosse is supporting the Breast Cancer Research Foundation (BCRF) and its mission to advance breast cancer research. By funding scientists and research institutions around the world, BCRF helps drive progress across key areas of research, from prevention and diagnosis to treatment, metastasis and survivorship.

Since the start of this partnership, La Bonne Brosse has donated $20,000 to help support BCRF’s work. This Breast Cancer Awareness Month, each Pink October product contributes to supporting the research funded by the foundation.

The Radiance Duo: a caring ritual to reveal your hair’s beauty

The Radiance Duo brings together the La Bonne Brosse Pink October Limited Edition brush and the Cair leave-in beauty cream, combining the benefits of brushing with daily care. Together, they help leave hair soft, smooth and radiant, while caring for the hair fibre day after day.

Available in several models to suit your hair type, La Bonne Brosse offers brushing tailored to every head of hair. Its 21 cm / 8.27 in size sits comfortably in your hand, making it easy to weave this caring gesture into your routine.

The leave-in beauty cream, daily care for your lengths

Designed as a true day cream for hair, the Cair leave-in beauty cream is a hydrating leave-in treatment that nourishes the lengths, coats the fibre and enhances the hair without weighing it down. Applied daily, it helps preserve your hair’s suppleness and hydration.

Its formula also works on frizz, rehydrates the ends and supports the natural definition of curls. Over time, hair becomes softer, shinier and more resilient against external stressors.

Paired with the La Bonne Brosse Pink October brush, it creates a two-step ritual to care for your hair and reveal its radiance every day.

Leave-in beauty cream: 100 ml, around 6 weeks of use.

La Bonne Brosse measures 21 cm / 8.27 in.

Five models with distinct qualities to help you choose the La Bonne Brosse that best meets your hair's needs.

Begin by gently brushing your hair with La Bonne Brosse, then apply Cair leave-in beauty cream to dry or damp hair, focusing on the lengths and ends.

Adjust the amount to your hair type: use 1 to 2 pumps for fine or short hair, and 3 to 4 pumps for long, thick, or sensitised hair.

Warm the cream lightly between your hands before distributing it evenly with your fingertips through the lengths and ends. As a leave-in treatment, it seamlessly fits into your daily ritual.

Biomimetic moisturising and repairing actives to enhance the hair fibre.

- Active waters of rice, grape and bamboo: they coat and moisturise the hair fibre without weighing it down
- Fermented organic nutrients: derived from a complex of 5 rich, revitalising oils, they are used for their nourishing power, enhanced by fermentation.
- Bond repair / biotechnology / biomimetic protective barrier: working on the keratin structure to repair fibres and regenerate lengths.
- Hyaluronic acid: it maintains moisture in the hair fibre throughout the day thanks to its ability to retain up to 1,000 times its weight in water.
- A heat-protective complex: derived from peptides, it is used to protect the hair fibre, making it more resistant to styling heat and the drying effects experienced by coloured hair.

This synergy of ingredients makes Cair hair cream a unique leave-in treatment that provides lasting moisture, protects and enhances the hair day after day.
