Kerastase Genesis Anti-Breakage Fortifying Serum 90ml

When comparing the Kerastase Genesis Anti-Breakage Fortifying Serum and the K Nutritive 8H Magic Night Serum, the primary distinction lies in their core functions. The Genesis serum is specifically formulated to address concerns around breakage and hair fall, offering strengthening benefits, while the 8H Magic Night Serum focuses heavily on intensive overnight care, providing deep nourishment, frizz control, and enhanced shine. While both products target general hair health and are suitable for various hair types, the Genesis serum's suitability spans a much wider range, including fine, greasy, and blonde hair. Conversely, the 8H Night Serum focuses its specialized benefits, such as deep moisturising and softening, primarily on dry, frizzy, and distressed hair. Therefore, your choice should align directly with whether your main goal is preventative strengthening against loss or intense overnight repair and smoothness.
