Generally, it's recommended to leave shampoo in your hair for about 1 to 3 minutes before rinsing. This allows the shampoo to effectively cleanse the scalp and hair.

The longer you leave it, the more pigments will be deposited on your hair and they could even stain it permanently.
Make sure you get washed immediately after you notice you have over-toned those locks! Most toners are not permanent, therefore eventually, after several washes, the 'cool' tones will fade. If you want that toner gone quicker, 2-3 washes with a clarifying shampoo will start to remove the blue, grey or purple stains.
