Bright red hair tint that lasts

[1989 hayley]

hi my client wants half black, half red hair (I've attached a picture) at the moment she has a 3 all over with a panel of red at the front, I currently use majicontrast red on it but it fades in about two weeks. to achieve this look I will have to bleach the hair up first to get it vibrant, does anyone know of any good reds that are vibrant and will last?
Thanks for any help

The more vibrant she goes the quicker she'll fade she could try a top up conditioner revlon nutricreme 600 and it's a conditioner aswell, just an idea

I used to use majicontrast red and I just used to mix directions red (whichever tone of red you like) into white conditioner and popped it on after I shampooed in shower as usual and it never faded x
I also used matrix SoRed and that was gorgeous too x
