PLEASE NEED HELP WITH HAIR PRODUCTS

I’m on my way to Sally’s and I really want to get this colored hair!! What products should I buy? My hair now is a light brown to medium blonde ombré, it’s very subtle.

I don’t have money to go to a professional and I really don’t want to box dye 😭

This is pretty much exactly the color of my hair

And this is the color I want to achieve.
