The Silver Shampoo from L'Oréal Professionnel Paris has been specially developed for white, gray, and bleached hair. Enriched with magnesium, the professional formula strengthens the hair fiber. The violet pigments contained in the shampoo neutralize unwanted yellow tones in the hair. This restores the shine and brilliance of gray, white, and blonde hair. This refill pouch contains 73% less plastic than the bottle format.
