What are ways to make my hair color lighter?

My hair is a little darker than dirty blonde...what are some ways to make it lighter w/o dyeing it? All I know is that sun can help because it brings out natural highlights. I've tried lemon juice, but it doesn't work well. Any ideas?What are ways to make my hair color lighter?
try vinegar! it brings through your natural highlites! it also makes hair soft and shiny. sun in is also great. just don't use those unpermanent hair dyes that say they wash out in 6 or so shampoos..they suck and will ruin your hair! trust me, i've tried them before. vinegar always worked for me!What are ways to make my hair color lighter?
pour clorox on it.
sun-in and a blow dryer will work, but try just a little at first so you don't overlighten.
There's a product called ';Sun In'; that you spray in your hair and works with UV rays to help lighten the hair. The more you use it the lighter your hair.
Use a wash of chamomile tea.
Just dye it! you can use a semi permanent dye and they make organic dyes too if you are worried about the chemicals.
die it or bleach it
