Does Lice Make Your Hair Fall Out?

Today, there are several ailments that can cause a person to experience hair loss. Among those causes are heredity (family history), poor nutrition, side effects from medications, certain diseases or ailments, stress and fluctuations in hormones, or hormone imbalances. Notice, however, that the presence of lice is not a cause or stimulus of hair loss.

Head lice are parasites that live on the human head. While there are other forms of lice that a human can get, head lice live on or occupy space on the human head while doing the things that they need to do to survive and reproduce. The warmth of the human head provides the exact temperature that lice need to survive. While there, they feed off of the scalp, sucking blood as their sole source of nourishment several times a day. They also reproduce, after a male and a female louse mate, the female louse will lay eggs on the individual strands of hair, up to ten eggs a day, and potentially over one hundred eggs during the course of her entire life span. These lice eggs (nits) are camouflaged as they tend to take on the color of the hair they are laid on. The nits are laid within one-quarter of an inch from the scalp as they need the warmth of the head to survive, and, once hatched, they need to feed soon after.

Considering the way head lice live, and the environment they need in which to survive, it would seem to be counterproductive to their life cycle for them to cause their human host to lose their hair. Head lice cannot survive on a bald head as they need the protective layer of the hair on the head to provide warmth. In addition, they need hair to help shield them from discovery and to continue with their daily activities uninterrupted. As mentioned previously, head lice need strands of hair to lay their eggs on – if the hair falls out, they will have no place to secure their eggs. Additionally, if there is an egg on an individual strand of hair that falls out, the baby louse (nymph) will die in the very off chance that they do hatch due to being separated from their food source.

So does lice cause hair loss? With regard to head lice as a cause of hair loss, taking into account the basic needs of lice to survive, it would stand to reason that it would not be practical for the long term survival of an infestation of head lice for these parasites to be a cause of hair loss.

Can Lice Cause Hair Thinning?

Thinning hair is a cause for concern for pretty much everyone, but especially so for girls and women. When hair starts to fall out, red flags go up. When dealing with a lice infestation and thinning hair, it would seem to be reasonable to conclude that the head lice are the cause for thinning hair. However, just as lice will not directly cause hair loss, it will not directly cause hair thinning. However, it is possible that head lice are the cause of stress, which is a known cause of hair loss and hair thinning.

According to the Mayo Clinic, there are three different types of stress that are associated with hair loss. These are telogen effluvium, trichotillomania (literally pulling your hair out), and alopecia areata. Once the primary source of the stress has been eliminated, the hair likely will grow back.

Can Lice Treatment Make Your Hair Fall out?

There are several treatment options to help you get rid of lice. The most effective treatment to get rid of head lice is combing with a professional nit comb. During the course of everyday combing or brushing of hair, strands of hair will become detached from the head; which is absolutely normal. The average person loses approximately from fifty to one hundred hairs every day. During certain phases or seasons, shedding can be more prominent, which is why you may, at times, notice more hair loss than usual. Because hair loss, or shedding, is normal, and hair naturally comes out during the course of brushing your hair daily, it is not unusual to notice some hair coming out during the comb out process of getting rid of lice, especially so when using a professional nit comb. Be that as it may, the combing and manual removal of head lice and nits is not the cause of any potential hair loss you may experience during the course of a head lice treatment.


Another treatment option that families often opt for is pesticide lice treatments. These can be purchased at local grocery stores or pharmacies, some of which require a prescription from your family physician. Over the counter lice treatments; such as permethrin (Rid, Nix) and prescription lice treatments; such as lindane, containing pesticides come riddled with undesirable, and potentially dangerous, side effects. These can include itching, burning, redness, swelling, stinging, tingling, numbness, rash, and even (with overuse) neurological damage. Notice, however, that these treatments are not associated with hair loss.
