How to get rid of head lice

Let’s find out a little bit more about how to remove lice.

  1. How to detect lice.

    To ensure you have every chance of catching lice before your child gets a full-blown head lice infestation, you should check your child’s hair weekly. Work in sections, checking every section of hair and the scalp. Checking your child’s hair regularly will help prevent the lice from spreading rapidly.

  2. How to get rid of lice by combing

    If you’re wondering how to get rid of lice naturally, combing can be very effective if the correct procedure is followed. Shampoo and towel dry hair thoroughly. Add a very liberal amount of hair conditioner or olive oil to the hair so the comb slides more easily through the hair shaft. Working from the root of the hair, comb the hair through to the ends using a lice comb. If the hair is long, section it with clips and work through the sections.
    Check the teeth of the comb for any nits or live lice, and rinse the lice comb well after each hair stroke. Repeat this every night for at least a week until you can no longer find live lice or eggs.
    This process will not kill lice. It will just remove them from your child’s hair.

  3. How to get rid of lice overnight

    Insecticide head lice treatments from the pharmacy can be applied to the hair and start working within a few minutes, depending on the manufacturer’s instructions. You will still need to use the comb-through technique described above to get rid of any dead lice and eggs.

  4. How to get rid of lice eggs in hair.

    Knowing how to get rid of nits or lice eggs and learning the common facts about headlice are the most important elements in killing lice. Because the lice eggs are cemented or glued onto the hair shaft, removing them can be very difficult. I’ve found the best way to get rid of lice fast is to use an over-the-counter lice treatment or lice killer to kill lice and eggs. After you have treated and rinsed the hair well, methodically comb the hair with conditioner and a nit comb as described above. Don’t rush this stage of the lice removal process, as it is important to remove any eggs that are alive and also any young newly hatched lice that may have hatched overnight. I prefer to repeat this process for up to a week after a lice infestation.

  5. How to get rid of lice when pregnant

    If you’re wondering how to get rid of lice naturally when pregnant or breastfeeding, you could try smothering the lice. A simple way to do this would be to use the comb-through method discussed above, using a couple of drops of tea tree oil mixed in with approximately 2oz of olive oil. This may help smother the lice and is one of the most popular home remedies. If this method does not work for you, you might seek medical advice on which over-the-counter methods are the best products without compromising you or your baby’s health.

  6. How to stop the spread of head lice

    If you find your child has head lice, you do not need to be embarrassed at all. Most children will encounter lice at some time in their lives.
    Check and treat all family members.
    Avoid sharing hats, pillows, brushes, combs, towels, and headphones for disease control.
    Ensure all towels and bedding are washed thoroughly in a hot wash.
    It’s always best to tell family, friends, other parents, and carers that your child has lice so that they can check their child too and treat them if necessary. Letting other parents know about a lice outbreak will help to control reinfection within your child’s friendship groups.
    Let your child’s teacher know there is a problem, too, so they can send a letter home with facts about head lice, advising all parents to check their children regularly.
    One of the main reasons schools have a problem with head lice is that not everyone checks their child’s hair regularly and doesn’t know how to treat head lice quickly should they discover any. Many people don’t know the full facts about headlice and how to get rid of them.

  7. Head lice prevention

    Knowing how to remove lice permanently is one of the best things you can do to stop a re-infestation.
    Tea tree oil is an effective way to repel head lice. Add a few drops to your conditioner or shampoo bottle to make a repelling head lice shampoo lice will avoid! This is one of the cheapest and most effective head lice home remedies. Special tea tree shampoos are also available, as are tea tree leave in hair sprays.

  8. How to get rid of lice with household items

    If you’re wondering how to treat lice with household items, butter, mayonnaise, or olive oil can sometimes be used to smother head lice. However, how well these methods kill head lice is debatable.
    Does peroxide kill lice? Unfortunately not, you can put that bottle back in the medicine cabinet!

  9. How to get rid of lice with vinegar

    Does vinegar kill lice? It is believed that vinegar may help dissolve the cement or gluey-like substance that adheres the eggs to the hair shaft.
    A solution of 1 cup of vinegar to 1 cup of water is used to apply to the hair. The solution is then left for a few minutes before rinsing. This may help the eggs to detach from the hair shaft. This method will not kill any lice or eggs. However, it may soften the gluey substance on the eggs to make them easier to remove from the hair when using the combing method described in step 2.
    This method should be repeated daily until the infestation has gone and no live lice or eggs are found in the hair.

  10. How to get rid of head lice with salt

    Little evidence suggests that salt is the best head lice treatment. One of the most common facts is that head lice can survive in water for up to half an hour and seem to cling tight to the hair shaft when submerged. If you’re looking for an effective way to eliminate lice in your hair, this might not be the best method, and you might want to try something else!
    If you want to try it for head lice removal, make a saturated salt solution using one pound of Epsom salts in a water basin and stir until dissolved. Saturate your hair with the solution as well. Leave for approximately 2 minutes, then rinse all the solution out well. Comb out the eggs and lice as directed above in step 2.

If you are struggling to get rid of a lice infestation, please seek medical advice, a treatment center, or help from your pharmacy service. You can read more about head lice at the British Association of Dermatology.
