The dog flea, (Ctenocephalides canis), are not adapted to survive on human hair due to the distinct characteristics of their bodies. Nonetheless, they can leap from a pet to a person, causing bites.

Although fleas cannot survive on human hair, you should try to avoid their bites as they may transmit harmful human pathogens, and in addition to that, their bites can cause serious itching.

Certain animals become attractive to fleas primarily due to their fur. Take, for instance, a dog covered with thick fur serves as an ideal nesting place for a substantial flea population. Within the fur, these insects can burrow deeply and lay their eggs, creating an optimal breeding environment.

Even if it happens, the flea wouldn’t find a suitable habitat on your head due to the limited amount of hair.

Neglecting the issue may lead to fleas spreading to other animals in your home, as these tiny insects are good at laying eggs wherever they can and can easily jump from one animal to another.
