Avant-garde treatment that uses innovative technology to keep your hair straight for 4 to 6 months. You will only need 5 minutes of combing with your hairdryer to maintain it. With French straightening you will get controlled volume without frizziness. It is a thermodynamic treatment that doesn't harm your hair fibre's structure. Moreover, it doesn't interfere in colouration processes, so you can dye your hair before or after this treatment without damaging the results. French straightening includes in its formula natural ingredients, such as purified water, natural keratin and hyaluronic acid, that provide hydration, flexibility, combing easiness without weighing the hair and an incredible natural brightness. It is done at the hairdresser's and lasts between 2 and 4 hours, depending on your hair's length. The treatment includes a 4-product kit: pre-treatment shampoo (2), the straightening treatment and a hair mask that keeps up and improves the duration of the treatment.
