Can Fleas Live in Human Hair? What’s the Real Truth?

Can fleas live in human hair? No, most fleas will not live in or on human hair; they are host-specific parasites. Host-specific means that they need a particular host to survive and procreate.

However, a flea can crawl across your hair if your home is infested with fleas. If a flea happens to crawl in your hair, it will not be making a home on your head.

The following types of fleas: [Pulex irritans] [Ctenocephalides canis] [Ctenocephalides felis] [Xenopsylla cheopis] can all feed on humans. However, none of them live in human hair.

Once adult fleas are on their host (whether a dog, a cat, a raccoon, or some other mammal), they rarely leave. The primary way fleas transmit from animal to animal is through an infested environment. For example, if you take your dog to the park and they walk by a flea cocoon in the grass, there is a good chance that a flea will emerge and jumps on them.
