Fleas usually go for pets, but they’ll bite people too, and if you’re dealing with a real infestation, they can end up on you specifically — hiding in hair or clothing since you don’t have fur to burrow into. Here’s how to actually get rid of them.

Wash your clothes first
Fleas hide in clothing more than people expect, since you don’t have the fur they’d normally burrow into. Wash anything you were wearing when you noticed the bites — hot water, and that alone clears out a chunk of the problem before you even touch your hair.
Dealing with your hair
Hot shower helps, but for actual fleas hiding in hair or a beard, you need something with real killing power, not just water.
A permethrin-based treatment is the better call here, not dog shampoo. Products made for human lice — like Nix — use permethrin at a concentration that’s tested and approved for human scalp use, and permethrin kills fleas the same way it kills lice. Dog shampoo wasn’t formulated with human skin in mind, and it’s just not worth the irritation risk when there’s a real, human-safe alternative sitting on the same pharmacy shelf.
Dish soap works in a pinch too — gentler than people expect, tough enough on fleas. Work it through, leave it about 10 minutes, rinse.
Baking soda, salt, and water paste shows up as a home remedy for this. Worth being honest: it’s low-effort but also low-evidence, more anecdotal than proven, and the salt can be a bit rough on the scalp. Fine to try if that’s what you’ve got on hand, just don’t expect it to outperform an actual treatment.
Whatever you use, follow up with a comb — a proper fine-tooth comb pulls out dead fleas (and eggs) that shampoo alone leaves behind. This step matters more than people give it credit for.
Keeping them off you going forward
Once you’re clear, a store-bought flea repellent spray on clothes and skin adds a layer of protection. If you’d rather go the homemade route, a diluted essential oil spray works reasonably well — mix water with a small amount of peppermint, tea tree, or citronella oil, keeping the oil well under 10% of the mix. Patch test on a small area of skin first, especially with tea tree oil specifically, since it can irritate sensitive skin even diluted.
Handle the actual source
None of this sticks if you don’t deal with where the fleas are actually coming from. Usually that’s a pet — cats and dogs are flea magnets simply because of the fur. Treat your pet with an appropriate flea shampoo, and don’t stop at just you and them — the house itself needs attention too, or you’ll be right back here in a couple weeks.
Clearing fleas from your house
Beyond pets, hair, and clothes, fleas hide in curtains, carpet, cushions, and furniture. Hot water or a flea-labeled spray handles fabric; regular vacuuming is genuinely one of the more effective tools for carpet, curtains, and under furniture specifically. Keep at it consistently rather than as a one-time fix — that’s what actually keeps a house flea-free long term.
Common questions
Where do humans actually get fleas from?
Mostly pets — cats and dogs bring them in and fleas spread from there. Visiting an infested space (a farm, another infested house) is the other common route.
How do you know if you’ve got them?
Small, itchy bite marks are the clearest sign. If your pet’s scratching constantly, that’s worth checking into as well, since it often means you’ve been exposed too, even before you notice bites on yourself. Some people feel movement under clothing or in their hair — fleas move fast, so you won’t always actually see one.
How long does it take to get rid of them?
Depends entirely on the method and how thorough you are. Some approaches work faster than others, and you’ll likely need to repeat hair treatments more than once before you’re confident they’re actually gone.
Bottom line
Pets are almost always the real source, so dealing with them matters as much as dealing with yourself. Wash clothes, treat your hair with something actually made for this (not a pet product), comb thoroughly, and don’t skip the house — vacuuming and repellent sprays keep it from coming right back.
