Does anyone have suggestions for a guy that wants to change hair color from dark brown to blond or dirty blond?

So I'm 18 and I am interested in changing my hair color. I am thinking about blond or dirty blond. But I don't want my hair to be really standing out and that is why I am thinking about dirty blond. I am wondering what is the best way to go about this. I have never done any coloring to my hair so this is a huge step for me. If there is any advice or tips on what I should do. Please let me know anything. Thank you. (also no snarky remarks, this is a honest question and i also would like to avoid being called gay for this)
