Well to start off I'm currently blonde right now. A little on the pale side, but I don't really care. I dyed it blonde a long while ago, so I'm not worried about my hair falling out. Anyways, I'm tired of being blonde, and I find my natural color very boring, and I want to go dark brown but there's a conflict. I have felt more confident and attractive with my blonde hair, and guys have seem to notice me more than they did, so I'm afraid I won't be as attractive if I dye my hair. Here's a pic of me as I am now:
I think that it will look pretty but I could tell you from experience that once you go that dark you will have trouble going back to blond if you ever wanted to go back. My hair was blond and I dyed it dark this year and then I decided I wanted to go back to blond and the hairdresser had trouble doing it because it was so dark. So really think about it before you do it.
i think you'll get as a dark brunette. if you feel like a change go for it. you can always dye with a semi-permanent hair colour, so if you don't like it will wash out. that what I always do when I feel like trying out a new hair colour and I have tried being all shades of brunette(from black to lightest brown), been a redhead and even tried the blonde side.
