HAIR RITUEL Sisley's Revitalizing Fortifying Serum. A scalp serum treatment that slows hair loss and improves hair strength and density. This exclusive hair treatment, rich in vitamins, minerals, proteins and plant extracts, acts directly on the scalp, favoring the growth of healthy and strong hair and drastically reducing hair loss. Its secret lies in the fact that its formula activates the hair bulb, thus improving the anchoring of the hair, giving it an advantage of resistance and protecting the natural tone. In addition, it has a smooth and light texture of rapid absorption, flavored with a pleasant and refreshing fragrance, which penetrates quickly without leaving a feeling of fat or heaviness. After its use, it immediately soothes any discomfort or discomfort of the scalp, thus leaving hair shiny, healthy and voluminous.
