There is no rule stating that goth hair has to be black.
There are many blonde goths, however they are extremely blonde, a platinum blonde bordering on white. Take your hair, then slick it back, if you don’t have platinum blonde hair already then take white hair spray dye and spray it.
I recommend this kind of look, it doesn’t have to be exact, just take it and put your own twist to it
I think these looks will look even better with blonde hair
