Head-to-head contact with an already infested person is the most common way to get head lice. Head-to-head contact is common during play at school, at home, and elsewhere (sports activities, playground, slumber parties, camp). Lice spread from person to person through close contact and by sharing belongings.
Can Bald People Get Lice?
People should treat head lice with OTC or prescription medications. Doctors typically recommend two rounds of treatment to ensure the medication kills all the lice and nits. The CDC recommends that all people in a family receive head lice treatment if one family member has them.

Storing clothing items in proximity also can lead to indirect transmission. Sharing school locker or hook space, or hanging multiple hats or scarves in the same place, could result in indirect transmission. People that get lice frequently like this should ABSOLUTELY use a lice repellent shampoo and spray in their hair every day.
Myth 3: Seeing 'nits' on the ends of the hair is a sign of an infestation that needs treatment
According to studies cited in a 2023 review, in industrialized countries, head lice infestations tend to occur in school-age children, as they often engage in close social contact. Head lice are tiny parasites that live on the human head and feed on blood from the scalp. They are common in children and spread as a result of head-to-head human contact, not through pets. If unhatched nits remain on the scalp, they will hatch within 9–10 days of being laid, and the lice will return. A person will have to repeat the process if this occurs as hair dye cannot penetrate the egg casing of nits.
Transmission in Children
Sometimes, a brand new wig made of real human hair will have nits in it. These are cosmetically undesirable, and you can use lice combs to remove them. But rest assured that the nits are just old empty eggshells, which are not a risk for catching lice. In order to get rid of head lice, you need to physically remove all of the bugs and nits from the strands. It does not matter how often you wash your hair or how long you shower; it will not get rid of head lice. You can submerge your head in water for six hours and not a single bug will die.

Hair casts slide easily along the hair, whereas nits stick to it and are harder to remove. People may be able to remove hair casts with coal tar shampoo or a fine-toothed comb. As their nickname suggests, adult crabs look like tiny crabs with roundish bodies and six legs. The color of pubic lice can also range from grayish-white to beige. Evidence of lice can often be found above or behind the ear, but they will not enter your ear—even if your ears are hairy. Itching inside your ears during a lice infestation is a sign of an allergic reaction.
lying on a bed, pillow, sofa, or carpet that had recently been in contact with someone who had head lice.
Anyone can get lice, regardless of age, social status, race or gender. Most health departments do not require reporting of head lice infestation. However, it may be beneficial for the sake of others to share information with school nurses, parents of classmates, and others about contact with head lice. If you are not sure if a person has head lice, the diagnosis should be made by their health care provider, local health department, or other person trained to identify live head lice. Many over-the-counter (OTC) lice treatments are available at drugstores.
Did you know that those little buggers aren't just creating a home on your child's head, but also sucking blood? Also, just like mosquitos, lice prefer some people's blood over others. Lice have become immune to everything that used to work in the past. Perhaps you remember your mom using a typical lice treatment or mayonnaise and that doing the trick. The new strain of head lice is no longer killed by those treatments, that’s why lice today are termed by people, “super lice,” because they are immune to those treatments.

Risk factors
Swollen lymph nodes can occur due to the excessive scratching injuring your skin, which leads to open sores and a bacterial skin infection. This causes the lymph nodes to take action to fight the infection. Excessive scratching of the eyes can cause you to develop pink eye (conjunctivitis).
A study showed that head lice had to be fully submerged in water for a full sixteen hours before they finally died. In addition, regular shampoo does not affect them in the least. In fact, even most “lice shampoos” these days are ineffective against head lice.
Nits (head lice eggs) generally die within a week away from their human host and cannot hatch at a temperature lower than that close to the human scalp. While anyone can get head lice, they are most common among children ages 3 to 11. Despite what some people think, head lice infestations are not a sign of poor hygiene.
The term nits can also refer to the empty egg casings that remain in the hair once the nymph has hatched. These are easier to see, especially on darker hair, as they are lighter, usually white or yellow. For more information, read Professor Speare's fact sheet on how to treat head lice. Some are chewing lice that feed off the skin and debris of their hosts.
Crabs are primarily spread by sexual contact and occasionally by infested clothing or bedding. Crabs on the eyebrows or eyelashes of children may be signs of sexual abuse. You can inspect for visual signs of head lice in a well-lit area using a magnifying glass, medical gloves, and a tongue depressor or pencil to move sections of hair. Lice need to get to the head in the first place, so you will likely not find lice on bald head with no hair to climb on. When the odd live bug actually makes it to a bald person's head, it may start feeding on blood, but it probably won't survive long.
