The Osmo Super Silver No Yellow Shampoo is a haircare product specifically formulated to neutralize and diminish yellow or brassy tones in blonde, gray, or bleached hair. This purple-toned shampoo contains violet pigments that work to counteract the unwanted warm tones in lightened hair, leaving it looking cooler and more neutral.

By using purple pigments, which are opposite yellow on the color wheel, the shampoo helps to balance out and neutralize the yellow tones that commonly occur in blonde, gray, or lightened hair due to factors like oxidation or exposure to elements like sun, chlorine, or minerals in water.

It's essential to use this type of shampoo with caution, as excessive use can potentially result in an overly cool or purple tint to the hair. Typically, it's recommended for occasional use (once or twice a week) to maintain the desired tone without overdrying or excessively toning the hair.

The Osmo Super Silver No Yellow Mask is a hair treatment product designed to neutralize and reduce yellow or brassy tones in blonde, gray, or bleached hair, much like the shampoo counterpart. However, the mask typically offers a more concentrated formula and is intended for deeper toning and conditioning effects compared to the shampoo.

Similar to the shampoo, the mask contains violet pigments that help counteract and neutralize the unwanted warm tones in lightened hair. It's used after shampooing and is left on the hair for a longer duration to intensify the toning effect and provide additional nourishment and moisture to the hair.

Users often apply the mask after shampooing, leaving it on for a specified amount of time (as per the product instructions) to allow the violet pigments to work on neutralizing brassiness and maintaining or achieving the desired cool tone in the hair.
