L'Oréal Paris Serioxyl Advanced Density Activator Serum 90ml

L'Oréal Serioxyl Advanced Density Activator Serum primarily targets boosting hair density and stimulating new hair growth, making it ideal for users seeking thicker hair. In contrast, Kerastase Genesis focuses on strengthening hair strands and reducing breakage to prevent hair loss, targeting hair resilience more than growth. Both offer the same quantity of 90ml, but differ in active ingredients and fragrance profiles, with L'Oréal users noting a potent scent and possible oily residue, while Kerastase is praised for a more refined woody citrus smell. According to user reviews, Serioxyl can improve volume over time, whereas Genesis tends to enhance hair strength and reduce shedding effectively. Ultimately, those aiming for thicker hair might prefer L'Oréal, while users wanting to fortify and protect existing hair may find Kerastase more suitable.
