THREE WEEKS TO GET FULLER, SHINIER, THICKER HAIR! Your hair ages too! Treat it to a three-week treatment to make it fuller, shinier, thicker, and more manageable. It's not just your skin that shows the signs of aging; your hair ages too. It loses its strength and vitality, just like the epidermis. To compensate for the biological deficiency in your hair linked to aging, you must nourish it. With this in mind, the Claude Bell Institute developed TONUS ANTI-ÂGE, a specific shampoo that restores hair's vitality and beauty. Ingredients: The TONUS ANTI-AGING shampoo is formulated with: - Ceramide A2, a physiological lipid that acts as a "natural cement" between the hair's scales, providing cohesion, structure, shine, and protection against external aggressions; - Rosemary extract, a plant with anti-free radical and antioxidant properties that combat chemical damage to the hair, but also promotes microcirculation in the hair follicles; - Argan oil, nourishing, revitalizing, and moisturizing. Clinical tests: Conducted over a three-week period, these tests showed: - A 33% increase in volume; - A 42% increase in shine; - Fuller hair: 57%; - A 31% increase in thickness; - A 75% increase in hair structure.
