While those styles sound really interesting... if you haven't dyed your hair before you might want to think hard about it. Dying can really mess with the 'health' (quality and texture) of your hair. .. That said I've always been a sucker for bottle-redheads as I know a lot of other guys are, so no ones going to be complaining.
I'm actually getting dreads some people say i act like a hippie and i so really act like a hippie sometimes so i decided to get my hair dreaded and put red highlights in it so i think it would look good, if it doesn't we can look badly highlighted together
I think it looks nice. Just know that any bright colors demand lots of maintenance and care. Otherwise it'll lose its brightness quickly and will end up looking dull... or worse, ugly. Red has a tendency to turn either pink or orange if you don't touch it up regularly. And depending on your tastes, you might not like it.
