Why are monkeys, chimps, orangutans and white people so hairy?
White people sometimes have thicker hairs. The actual number of hairs is pretty consistent with other groups. Hair is a response to environment. Straight hair seems to be a better heat insulator. The curly hair is better at protecting from too much sun yet not insulating heat too much. There are lots of features that racists can use in comparisons. Those features are soon found superficial by an intelligent person.
