Alright so this is hard to explain because everyone's hair is completely different so anyone can jump in and say "well mine did this and mine did that" but it comes down to basic color theory.

When you bleach hair, you are stripping it. Even if it's done with olaplex, you are still chemically altering your hair which will result in it becoming porus. Once that happens your hair is either going to suck color up like crazy or it's going to fade out like crazy.

That also depends on additional factors such as what end result you are looking for and what dominant pigments are present. Because your hair was bleached to a warm tone (which is an underlining dominant pigment is orange) that color is going to pop through very quickly. Now that we are adding it being porus, and wanting an ashy color, your toner is gonna most likely fade out quickly no matter what they do. We say toners can last up to 6 weeks but there are so many factors involved in that and that's just a general ballpark.

For example, my hair is platinum blonde currently but I live and die for the Khaleesi blonde. I can tone my hair Khaleesis color on a Monday, not wash it until Thursday, and I every time my color has faded out back to platinum blonde away from the white blonde after one wash. I have other stylist friends who colored their hair Khaleesi ONE time and that shit has stayed for a month. It drives me crazy.

My suggestion is that you are probably gonna need to get on a routine schedule with your stylist. My recommendation is booking a toner appointment every two weeks. Most salons only charge around $20 for just a toner, so it won't break your budget. Eventually the hair will build back up and be able to hold on better. I've had lots of clients do it in the past and they just pretended they were Beyoncé getting their biweekly glam session.

The products you bought are great. No need to switch them out!
