Because it's historically ignorant? IANA ethnographer, but I expect that until the collapse of antiquity/migration period, only a vanishingly small part of the population did not share the most prevalent phænotype (dark hair etc.) in the cis-alpine part of the peninsula. I distinctly remember from school that blonde natural hair wigs were a prized possession among Latin female nobility because it was so rare to see and so difficult to obtain because of distance.
