How to dye blonde hair brown?

WELL you can go to Google and find a hair site that let's you upload ur picture and try different shades and stuff and also...never use ASH!! Ash is horrible. It either turns brown hair some weird color, and it always meshes badly with blonde i dont understand why they even sell any hair dye with "ash" for hair. (I'm a blonde) any hair dye you use going from blonde to brunette you should be fine. Just steer clear from ash colors, also try comparing your hair colors to the colors on the boxes at the store since yoyve already dyed ur hair with ash, its fine, but i dont know how healthy ur hair is and you dont want to do to much hair dying in one day..so if you think yiur hair can handle it or the color is just horrible you cant leave the house or whatever than dye it just do any brunette color u like and it will be fine!. Also---if you have a Sally's beauty supply near by, go there they are inexpensive and have great beauty/hair products. Good luck, and treat your hair good with deep treatments weekly!

Because you already dyed it I would recommend you to buy just a little shade darker or even the same shade again.
