ReVital Elixir – The Power of Silk for Revitalized Hair Modern salon treatments — coloring, chemical straightening, perms, bleaching, and thermal styling — can transform your look, but they often leave hair weakened, dry, and vulnerable. ReVital Elixir SeriSilk was created to restore what salon processes take away: strength, resilience, and shine. At the heart of the collection lies the SeriSilk Complex, a unique blend of natural silk proteins, keratin derivatives, essential fatty acids, amino acids, vitamins, and nourishing botanical extracts.
