Head lice are tiny, wingless insects that feed on human blood. They are typically found on the scalp, but can also be present in other hair-covered areas of the body, such as eyebrows, eyelashes, and facial hair. Head lice spread through direct contact with an infested person, or by sharing personal items such as combs, hats, and towels.
Causes of head lice in adults
Contrary to popular belief, head lice are not caused by poor hygiene. Anyone can get head lice, regardless of their age, gender, or socioeconomic status. The most common way to get head lice is by coming into contact with someone who already has them. This can happen through close personal contact, sharing personal items, or being in crowded environments such as schools, camps, and nursing homes.

Symptoms of head lice in adults
The symptoms of head lice in adults are similar to those in children. They include:
- Intense itching on the scalp, neck, and ears
- Redness and irritation of the scalp
- Small, red bumps on the scalp, neck, and shoulders

Diagnosis of head lice in adults
Diagnosing head lice in adults is typically done by inspecting the scalp and hair for lice and nits. This can be done by using a fine-toothed comb to comb through wet hair and looking for live lice or nits that are attached to the hair shafts. If you suspect that you have head lice, it is important to confirm the diagnosis with a healthcare professional.
Treatment options for head lice in adults
There are several treatment options for head lice in adults, including over-the-counter products, prescription medications, and home remedies. The most commonly used treatments include:
- Permethrin lotion or cream, which is applied to the scalp and hair and left on for a specific amount of time before being rinsed off.
- Pyrethrin and piperonyl butoxide shampoo, which is also applied to the scalp and hair and left on for a specific amount of time before being rinsed off.
- Ivermectin lotion, which is a prescription medication that is applied to the scalp and hair and left on for a specific amount of time before being rinsed off.
- Manual removal, which involves using a fine-toothed comb to remove lice and nits from the hair.
Home remedies for head lice in adults
In addition to conventional treatments, there are several home remedies that can be used to treat head lice in adults. These include:
