Most results I've seen from people with naturally blonde hair do not really achieve the quality that I would personally find acceptable from getting work done on myself. You can generally see right through the hair at a reasonably close distance and like
@pegasus2 said, the density requirements are much higher then someone with naturally dark hair.
You can however get great results from having dark hair and bleaching your hair afterwards. Machine Gun Kelly is the textbook case of this. His hair has the thicker density of naturally darker hair but when he bleaches it the result is much better because the contrast is great. I have a feeling if his hair was darker now he wouldn't be able to pull off these types of hairstyles because the density vs contrast would be more apparent.
The issue isn't the color of the hair itself, it's the natural characteristics of each hair type.
