If you do a search on the internet, you can read articles that advise you to let your blue shampoo sit for several hours so that its effect is doubled.
This is however not recommended by professionals, due, once again, to the drying properties of this type of shampoo.
This technique can however be interesting if you want to add blue or purple reflections to platinum blonde coloring.
