L’Oréal Professionnel Série Expert Serioxyl Advanced Density Activator Serum is designed for individuals experiencing thinning hair, aiming to enhance hair density and achieve a fuller appearance. This lightweight serum is enriched with 5% Stemoxydine, a patented molecule that awakens dormant follicles to stimulate new hair growth, and Resveratrol, a powerful antioxidant that enhances the efficacy of Stemoxydine by optimizing hair cycles and promoting follicle renewal. Clinical studies have demonstrated significant improvements in hair density and volume with daily use over a 12-week period. To use, apply the serum evenly on the scalp, ideally at night on towel-dried hair. Part the hair into four sections and spray six times in each section. Gently massage with fingertips and leave on without rinsing. This serum is suitable for all hair types and is free from silicones, ensuring a natural feel. Incorporate this serum into your daily routine to achieve visibly denser and thicker hair.
