How can I get natural blonde highlights in my hair?

I tried lemon juice but I don’t think it was pure lemon juice, it worked barely but its not that noticeable. I don’t want to dye it and I just want natural high lights. I’ve also heard certain kinds of vinegar. (I have brown hair btw). Does bleach turn your hair like BLEACH blonde or just normal blonde? If you mix bleach with water is it not as an intense whitey color or does that not do anything? Also does anyone know of any tips to help my hair grow faster? My hair grows REALLY slow like an inch and a half a year. I do straighten it almost everyday, but so does my sister and hers grows way faster.
