I just dyed my hair blonde and didn't like the colour so have dyed it 3 other shades in the past 3 weeks and yet I still think the colour looks awful against my complextion do you have to be particularly tanned or pale to pull of blonde or am I just missing something

Best bet is to put on a wig when you think of dying your hair another colour, then you can actually see how your complexion looks with the colour you want to be.

You are destroying your hair and won't have to worry about your complexion if you don't have any hair left !

My suggestions, and IMO. Go get your hair cut, let it grow out to your natural colour, don't fool around with it, be healthy and happy in your own skin(and your own hair!). Go to an expert and receive an informed decision. Most beauty experts nowadays have computer imaging to show you how you will look with whatever you desire and advice you on what looks best. Sometimes its worth the money you spend to have this done with no headaches and no DISASTERS !

Let your hair rest from all this dying or your going to damage it really bad like I did once
