How long should silver shampoo be left in haar?

Silver shampoo works best when you allow it some time to absorb, so the pigments can do their job. Usually, 1 to 2 minutes is enough to neutralize unwanted yellow tones. However, always check the instructions on the packaging, as they may vary by product.

Keune Care Silver Savior Shampoo is an excellent choice for combating unwanted yellow tones in blonde or grey hair.
