How long does pink take to get out of hair?

I have natural light blonde hair I would say and I wanna dye the whole thing neon pink but this would be the first time I’ve done that. I’ve done colored highlights but never this. I was wondering how long would it take for my natural hair color to come back. I’m not super into beach because I feel like it my not natural hair color(I’ve done partial highlights twice in my life) so just wondering if it would come out naturally or stay peachy or pale pink for years and years
