Can products from the Blond Absolu range be used on natural blonde or grey hair?

Blond Absolu is designed for bleached and highlighted hair, but can also be used for natural blonde or grey hair in search of shine and care. Neutralising products are designed to eliminate yellow and copper reflections.

What is the source of the repairing effects in the Blond Absolu range?

Inspired by skincare, Blond Absolu range is formulated with ingredients that contain regenerating properties that repair hair fibres from the inside and offer lightweight protection: Hyaluronic Acid and Edelweiss Flower.

How often should I use Ultra-Violet shampoo and Ultra-Violet mask?

Ultra-violet treatments are enriched with blue and purple pigments to preserve the cool reflections of polar blondes. They can be used as regularly as required for the desired degree of neutralisation.

What precautions should be taken when applying Ultra-Violet shampoo and Ultra-Violet mask?

As with any product composed with pigment, the risk of allergies is possible: We recommend taking an allergy test at least 48h prior to usage, wearing gloves for protection.

How do I protect my already weakened bleached hair from heated appliances when brushing or styling?

It is essential to protect the hair before using styling appliances. Apply Sérum Cicaplasme before blow-drying or straightening, to protect hair from heat, smooth lengths, and reduce split ends.
