How do I dye my brown hair blonde?

my natural hair color is medium brown, well I've always wanted to go 2 a dirty blonde color for years now.so I went to go get it professionally done in December and after of hours sitting there it ended up a strawberry blonde color more red ( I dunno if it was because she mixed to different blondes together)...so few days later I just said screw everything and just go back to a brown color, I think I got light ash brown from loreal...but then in the sun I noticed I have red tones in my hair (which I dont want) and everything so I figured I would give blonde another try but reading up on brunettes going blonde from what other people are saying its seems to me its freggin impossible to go blond with no orange tone or red tone or whatever, so right now I still have the light ash brown color but I frosted it so its kinda blonde but not the blonde I want, so should I just keep highlighting for a while until it gets blonde enough to dye with no problems or am I just wasting my time?

and don't tell me to go to a professional I just want some tips to get my hair blonder... oh and since I've frosted my hair my roots are coming in which is bugging me to so I need to dye it all one color but I dunno if blonde would take or not without me looking like a red head. thanks for the people who can help me

can someone tell me what to buy at like sallys beauty shop or walmart or something

okay well bleach it on a friday or saturday and dont go outside because it'll be alittle tinted and then the next day dye it the color that you want and it;ll be totally fine I promise I did the same thing...condition it a lot

yeah...
you can go buy a bleach that bleaches your hair blonde.
then if it is to blonde,get some more hair dye and dye it a little darker like Dirty blonde or some lighter blonde color.
trust me.
I am a natural blonde.

ooohhh I wouldn't bleach it. believe me it will never be the same. my natural fair color is a dark brown I went and got my hair professionally down it took forever but it was worth it before they dyed it the color I wanted they put in another dye to take the red tones out and then they died it the dirty blonde color and then put highlights it was like 110 bucks but it was worth it but it wasn't the exact blonde that I wanted to after that I just started doing it at home since they already got the red out it's easy and I just buy revlon golden blonde color and dye it at home and every 2 months I go and get my highlights for 35 bucks and I love it! hope that helped!!!
