Patients can have an infestation by Pediculus humanus capitis (head louse) on hair, beards, moustaches, eyebrows and eyelashes. They spread by having direct hair-to-hair contact with a person who has head lice. They can also spread from indirect contact with items such as hats, towels or combs.
Other Hair
Meaning head lice don't often infest beards and mustaches. Facial hair is often coarse and widely spaced. This makes it difficult for head lice to live comfortably and attach. It is extremely rare for head lice to infest facial hair though it does happen on rare occasions.
To rid your beard of these tiny horrors, start with a fine-toothed comb to methodically remove the lice and their nits (eggs). Over-the-counter medicines, lotions, and shampoos containing 1 percent permethrin, or pyrethrins and piperonyl butoxide, are often effective in staving off the pests.
Head lice survive less than one or two days if they fall off the scalp and cannot feed. Head lice eggs (nits) cannot hatch and usually die within a week if they do not remain under ideal conditions of heat and humidity similar to those found close to the human scalp.
Body lice most often affect people who aren't able to bathe or wash clothing often, such as homeless people. Pubic lice, also called crabs, that occur on the skin and hair of the pubic area. Less often, they may be found on coarse body hair, such as chest hair, eyebrows or eyelashes.
Heat Method:
There are recent studies that show that treatment of lice with heat can be quite effective in killing head lice. Products such as Lousebuster are very effective but even a home hairdryer can successfully treat lice.
Itching on the areas where head lice are present is the most common symptom. However, it may take up to 4 to 6 weeks after lice get on the scalp before the scalp becomes sensitive to the lice saliva and begins to itch. Most of the itching happens behind the ears or at the back of the neck.
Nits that are attached more than ¼ inch from the base of the hair shaft are almost always non-viable (hatched or dead). Head lice and nits can be visible with the naked eye, although use of a magnifying lens may be necessary to find crawling lice or to identify a developing nymph inside a viable nit.
Lice and nits can live on pillows and sheets. Lice glue their eggs to the hair strands of their host. However, if a piece of hair with an egg falls out while the lice host is sleeping, an egg could end up on pillows or sheets.
If we do find head lice in your beard, most men choose to shave the beard, which is a perfectly acceptable way to eliminate it.
Shaving Will Not Get Rid of Lice.
The reason shaving will not work is because lice live on the base of the hair, and on the scalp. The nits are laid right at the base of the hair oftentimes against the scalp. Shaving will not get close enough to make an impact on the lice and nits.
Shaving the head does not cure lice. The itching should go away within a few days, but the medicated treatment will need to be repeated in 5 to 7 days to kill any new lice that may have hatched since the first treatment.
The head louse, or Pediculus humanus capitis, is a parasitic insect that can be found on the head, eyebrows, and eyelashes of people.
If you recently experienced a head lice infestation and upon a post-treatment head check, you find nits but no lice, it is possible that these nits are leftover from that infestation and are no longer viable.
There are two reasons for a recurrent lice infestation: The lice treatment you used didn't work. You or someone in your family came in contact with lice again.
If you're infested with body lice for a long time, you may experience skin changes such as thickening and discoloration — particularly around your waist, groin or upper thighs. Spread of disease. Body lice can carry and spread some bacterial diseases, such as typhus, relapsing fever or trench fever.
Key takeaways: Formication is the sensation that bugs are crawling on or under your skin when they don't really exist. Causes include mental health conditions such as depression, medical conditions like Parkinson's disease, certain prescription medications, or drug use.
You Have to Treat Them
Head lice will not go away on their own. If you think your child has an infestation, there are several steps you should take right away. Call your doctor to confirm the diagnosis. Notify your child's day care or school so other students can be checked.
Coconut, tea tree oil, lavender, eucalyptus, rosemary, lemon grass, and peppermint are scents popularly believed to repel lice. Using any coconut scented shampoo and conditioner is an easy way to increase your defense. At 1% concentration, tea tree oil killed 100% of head lice after 30 minutes.
Do not use a conditioner. It can keep the lice medicine from working. Rinse well with warm water and towel dry. Do not use the towel again until it has been laundered.
Simply washing the items in hot water and drying them at a high temperature should get rid of the critters. The head louse (Pediculus humanus capitis) is easily killed by temperatures above 122 degrees Fahrenheit, and the typical residential hot water temperature is about 130 degrees.
Tea tree oil works by repelling lice because of its insecticidal properties. In addition to keeping the hair tied up and artificially dirty, you can use tea tree oil to repel a head louse looking for a new home. You may also include lavender essential oil or peppermint essential oil for this purpose.
