How will I know if I'll look good blonde?

I've always wanted to go blonde like Sarah Harding from girls aloud but dunno if it will wreck my hair or if it will be ok. I have naturally normal brown hair and wanted to know whether it will look good please help!!

I don't know whether or not it will look good, since I can't see you and have no idea what you look like. So I can't help you there.

Going blonde when you have your natural haircolor still is an easy enough task. Just a couple hours in a salon with a styist.

Go for it. As far as it wrecking your hair--the odds of that happening are very, very, very slim. Especially if you have virgin hair. Just go to a stylist and have a consultation about it. She'll tell you how the process will work.
