Lice cause itching on the scalp, especially around the ears (behind them) and the back of the neck, due to allergic reactions to their bites, which can also feel like something is crawling in your hair. For body lice, itching occurs where clothing seams touch the skin (waist, groin, armpits). Pubic lice cause itching in coarse hair around the genitals or anus.
Only 1 in 3 people with head lice experiences itching. It is worse behind the ears and at the back of the neck. Itching is caused by an allergy to the saliva of the louse, and it may be several weeks before it occurs.
Wet combing or dimeticone are the preferred choices to treat head lice in breastfeeding. Malathion may also be used as an alternative. Other preparations (isopropyl myristate/cyclomethicone or isopropyl myristate/isopropyl alcohol) can be considered after other treatment options have failed.
Symptoms of head lice include:
Medicated lotions and sprays
Head lice should die within a day. Some lotions and sprays come with a comb to remove dead lice and eggs. Some treatments need to be repeated after a week to kill any newly hatched lice. Check the pack to see if they're OK for you or your child to use, and how to use them.
Getting head lice isn't a sign of poor hygiene or unclean surroundings. Head lice prefer clean hair to attach and lay their eggs. Another common misconception is that head lice can jump or fly from one person to another. Head lice only crawl, most often leading to transmission through direct head-to-head contact.
Itching (pruritus) is the most common symptom of head lice infestation. It is caused by an allergic reaction to louse bites. It may take four to six weeks for itching to appear the first time a person has head lice.
Smothering agents: There are several common home products that may kill lice by depriving them of air and smothering them. These products include petroleum jelly (Vaseline), olive oil, butter, or mayonnaise. Any of these products may be applied to the scalp and hair, covered with a shower cap, and left on overnight.
There are many other causes of scalp itching that can be mistaken for head lice. These include folliculitis, psoriasis, eczema and dandruff, but they do not have the features mentioned above.
Our head lice treatment service can help you banish lice as part of our free NHS Minor Ailments service. No appointment is needed, all you have to do is provide is with information showing that you are registered with a GP in the local area and bring a sample of the confirmed head lice.
Comb sections of hair using a fine toothed lice comb.
Rinse the comb in a sink or bowl of warm water, and wipe dry. Continue section by section until the entire head is done. Make sure hair stays wet with conditioner during combing. Metal or plastic nit combs are available at your local pharmacy.
Hedrin® Lotion can be used in pregnant and breastfeeding women and in children aged 6 months to 2 years, as it is licensed for use in these groups.
People who have head lice for the first time may not feel itchy right way. It can take 4 to 6 weeks for itching to start. You may be able to see lice, but they move quickly, avoid lights and are small. You may also see lice eggs on hair shafts.
Lice dislike the aroma of peppermint, hence its function as a repellent; however, peppermint is not harmful to lice. To kill lice, a substance must enter the breathing mechanism and remain there for long to strangle them. There are more effective alternatives to peppermint oil that can be used in killing lice.
Adult lice can only live a day or so without blood for feeding and nymphs can only live for a few hours without feeding. Nits will generally die within a week away from the host and cannot hatch at temperature lower than that close to the human scalp.
Body lice treatment
If you have body lice, the first step is to wash yourself with soap and hot water. You also need to wash any contaminated items, such as clothes or bedding, in hot water. Dry them in a clothes dryer on high heat. Any clothes that can't go in a washing machine should be dry-cleaned or ironed.
Common black bugs found in hair besides lice include fleas, bed bugs, gnats, and other small flying insects. Each has distinct characteristics and requires different treatment approaches.
Use fingers to separate hair and create a part. The part should allow you to clearly see the person's scalp. Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed.
The best way to check is by using a fine-tooth comb on wet hair. After applying lots of conditioner, comb the hair out in very small sections, and look for lice or nits on the comb. You can wipe the comb onto a tissue or paper towel where it will be easier to see them.
After the first treatment, when the egg-laying lice are eliminated, you are no longer contagious. To stop the cycle of lice you must stop the egg laying first, then remove the nits.
If using Nix or Rid, it is recommended that you shampoo with the lice shampoo again on the 9th day after the initial shampoo. This step may not be necessary for Sklice. If you continue to see live bugs 2 days after shampooing, please call our office for recommendations.
Note: If you will be using Nix, do not use hair conditioner or any other substance that might block the residual action of the pesticide after treatment. If you want to use vinegar or products such as Clear and Step 2 to help with nit removal, apply and comb out the nits before you shampoo your child's hair.
