L'Oréal Serie Expert Silver Shampoo is a professional neutralizing shampoo formulated for grey, white, silver, platinum, and light blonde hair to eliminate warm, brassy, and yellow tones. Infused with violet micro-pigments, it helps restore cool tones and maintain the purity of natural or color-treated white and grey hair. Enriched with Magnesium to strengthen the hair fiber and Amino Acids to protect against external agents, it gently cleanses while nourishing and protecting, leaving hair soft, clean, and shiny. The Gloss Protection System maintains the hair's purity while enhancing softness, suppleness, and shine. For best results, distribute evenly through wet hair, massage into a lather, and leave in for up to five minutes before rinsing thoroughly. Use one to two times per week depending on desired neutralization, and follow with L'Oréal Professionnel Silver Anti-Brass Purple Conditioner for maximum results.
