Can I go back to blonde without looking bad?

I dyed my hair brown and now want to go back to my natural color blonde. Can it be done? Without wrecking my hair and without looking tatty ??

I have the same problem but I dyed it black & I'm blonde but the dye has faded now and itz a brown now. But have you tried washing your hair with washing powder twice a day try it my hairs iz getting a bit lighter every day!! good luck =)
