How to Clean Hair Brushes After Lice

  • by

When dealing with lice, it’s crucial to ensure that your hairbrush is entirely free from these pesky critters. Properly cleaning your hairbrush is a key step in preventing reinfestation.

In this comprehensive guide, we’ll walk you through the entire process in a straightforward manner.

Gather Your Supplies

Before you start cleaning your hairbrush, it’s essential to have all the necessary supplies at hand.

Here’s what you’ll need:

  • Hot Water: The hot water will serve as a natural lice killer.
  • Fine-Tooth Comb: This comb is handy for removing lice and nits from the brush.
  • Cleaning Solution: You can use a mild shampoo or a specialized lice-killing solution.
  • Disposable Gloves: Wearing gloves is essential to avoid direct contact with lice and cleaning solutions.
  • Container: Find a container that’s large enough to soak your hairbrush in.


Before you start cleaning your hairbrush, take some precautions to avoid any further spread of lice. Lice can be quite contagious, and you want to make sure they don’t find a new home.

  • Wear Gloves: Put on disposable gloves to protect your hands from coming into direct contact with lice or any cleaning solutions.
  • Dedicated Lice Comb: If you have one, use a lice comb specifically for this purpose. It will help prevent cross-contamination.

Initial Brush Inspection

The first step in cleaning your hairbrush is to inspect it carefully for any signs of lice, nits, or hair strands. It’s important to do this before you start cleaning to get a clear picture of the extent of the problem.

  1. Examine the Bristles: Look closely at the bristles of your hairbrush. If you see any lice, they’ll typically be tiny and brownish, often clinging to the base of the bristles.
  2. Nits (Lice Eggs): Check for nits, which are small oval-shaped eggs that are usually attached to individual hair strands. They can be translucent or pale in color.
  3. Loose Hair Strands: Remove any loose hair strands from the brush. Hair strands can make it easier for lice to hide.

Inspecting your brush thoroughly at this stage will help you determine how extensive the cleaning process needs to be. If you discover only a few lice or nits, you may not need to go through the full deep-cleaning process.

Once you’ve gathered your supplies and inspected your hairbrush, it’s time to move on to the next steps in the cleaning process.

Soak in Hot Water

Hot water is a simple yet effective way to kill lice and nits.

Follow these steps:

  1. Fill a Container: Take your container and fill it with hot water. The water should be hot enough to kill lice but not boiling, as boiling water could damage your hairbrush.
  2. Submerge the Brush: Place your hairbrush in the container, ensuring that it’s fully submerged. Leave it in the hot water for about 10-15 minutes. The heat will kill lice and nits effectively.

The hot water step is crucial as it eliminates any live lice and nits that may be present on your hairbrush.

However, it’s essential to remember that it may not remove all the debris, so we’ll proceed with further cleaning steps to ensure thorough sanitation.

Scrub and Disinfect

Now that your brush has been soaked, it’s time to scrub and disinfect the bristles. This step will help remove any remaining lice, nits, or debris.

  1. Remove the Brush: Carefully remove the hairbrush from the hot water.
  2. Apply Cleaning Solution: Use a mild shampoo or a specialized lice-killing solution to clean the bristles. Apply the solution generously to cover the entire brush.
  3. Scrub the Bristles: With a fine-tooth comb or an old toothbrush, scrub the bristles thoroughly. Pay close attention to the base of the bristles and the crevices where lice and nits might hide.

This step is crucial for ensuring that your hairbrush is free of lice and nits. The cleaning solution and scrubbing action will help dislodge and remove any remaining pests.

Rinse and Dry

Once you’ve completed the scrubbing and disinfection, it’s essential to rinse your hairbrush and allow it to dry thoroughly.

Here’s how to do it:

  1. Rinse Under Hot Water: Rinse the hairbrush thoroughly under hot running water. Make sure you remove all the shampoo or cleaning solution from the bristles. You don’t want any residues left on the brush.
  2. Allow the Brush to Dry: After rinsing, set the hairbrush aside and let it air dry completely. Lice can’t survive without a host for more than 24-48 hours, so this drying period ensures that any remaining lice or nits die.

Deep Cleaning (if necessary)

In more severe cases or if you want to be extra cautious, consider these deep cleaning methods:

  1. Disassemble the Brush: If your hairbrush is designed for easy disassembly (detachable bristles or pads), disassemble it to access hard-to-reach areas.
  2. Use Specialized Products: Some products are formulated specifically for lice removal from hairbrushes. Follow the manufacturer’s instructions for use. Typically, you’ll apply the product, allow it to sit for a specified time, and then scrub and rinse the brush.

Deep cleaning methods are a good option when you suspect a heavy infestation or want to ensure no trace of lice remains on your brush. These steps can provide an extra layer of protection.

Preventative Measures

Preventing future lice infestations is essential once you’ve gone through the effort of cleaning your hairbrush.

Here are some preventative measures to consider:

  1. Launder Bedding and Clothing: Lice can survive on bedding, clothing, and towels. Wash and dry them at high temperatures to kill any potential lice and nits.
  2. Hair Accessories and Hats: Any accessories that come into contact with your hair, such as hair ties, headbands, and hats, should also be washed or disinfected.
  3. Educate Family Members: Lice are highly contagious. Make sure everyone in your household is aware of the situation, so they can take preventative measures too. Teach them how to recognize lice and nits.
  4. Regularly Check Hair: Keep an eye on family members’ hair for signs of lice. Early detection can prevent a small problem from becoming a big infestation.
  5. Use Lice Repellents: There are natural lice repellents like tea tree oil and lavender oil. A few drops of these oils on combs and brushes can deter lice from taking up residence.
  6. Avoid Sharing Brushes: Teach family members not to share hairbrushes, combs, or headgear. Sharing is one of the most common ways lice spread.
  7. Vacuum and Clean Living Areas: Vacuum upholstered furniture, car seats, and other areas where lice could be lurking. Dispose of the vacuum bag carefully.

Preventative measures are crucial to ensuring that lice don’t return. By maintaining a clean environment and educating your family on lice prevention, you can significantly reduce the risk of future infestations.


Regular maintenance of your hairbrush is a simple habit that can go a long way in preventing lice from coming back:

  1. Weekly Brush Inspection: Make it a routine to inspect your hairbrush every week for any signs of lice, nits, or debris. The sooner you catch an issue, the easier it is to address.
    • How to Inspect: Examine the bristles closely, looking for tiny brownish lice or translucent nits attached to hair strands. If you spot any, it’s time for a quick cleaning.
  2. Quick Cleaning: If you spot any lice or nits during your weekly inspection, give your hairbrush a quick cleaning as outlined. This immediate action can prevent a full infestation from taking hold.
    • Quick Cleaning Recap: This involves disassembling your hairbrush (if possible), soaking it in hot water, scrubbing the bristles with shampoo or a lice-killing solution, rinsing thoroughly, and allowing it to air dry.

By integrating these simple maintenance tasks into your routine, you can stay one step ahead of lice and prevent them from returning.

Final Thoughts

Lice infestations can be quite a nuisance, but with the right knowledge and a little effort, you can successfully eliminate them from your hairbrush. Here are some final thoughts to keep in mind:

  • Persistence Pays Off: Lice may be persistent, but so are you. Don’t be discouraged if it takes time to completely eliminate them. Consistency in your cleaning routine is key.
  • Prevention Is Key: The best way to deal with lice is to prevent them in the first place. Make sure everyone in your household is aware of lice prevention measures, like not sharing brushes or hair accessories.
  • Early Detection Matters: Regularly check the hair of family members for signs of lice. The earlier you detect an infestation, the easier it is to manage.
  • Clean Your Living Spaces: Remember that lice can lurk in various places. Vacuum upholstered furniture, car seats, and any other areas where they might hide. Dispose of the vacuum bag or contents carefully.
  • Stay Informed: Lice and their prevention methods may evolve over time. Stay informed about the latest developments in lice control and prevention to maintain a lice-free environment.
  • Don’t Hesitate to Seek Professional Help: If lice infestations become severe and persistent, consider consulting a healthcare professional or a lice removal specialist for guidance and assistance.

Lice can be a pesky problem, but with knowledge, persistence, and preventative measures, you can keep them at bay.

By following the steps outlined in this guide and maintaining a vigilant approach, you can ensure that your hairbrush remains a lice-free zone.

Remember, you’re not alone in this battle. Lice infestations can happen to anyone, but with the right approach, you can protect your family and keep those unwanted guests away.
