how to sterilize combs
There is no need to doubt that sterilizing your comb regularly is healthy for your hair!

These days, combs are an essential personal care tool, however, many people may neglect to clean and sterilize their combs. During use, combs tend to accumulate flakes, oils, and dirt, all of which can be breeding grounds for bacteria, fungi, and viruses. If not sterilized regularly, these pathogens can spread through the comb, leading to skin diseases or hair health problems. Therefore, how to sterilize combs?

How to sterilize combs?

1. Disinfecting with alcohol

Sterilizing with alcohol is a simple but effective way to sterilize combs.

  • Prepare alcohol: You need to prepare a certain concentration of alcohol, usually, 75% medical alcohol is the most suitable for disinfection. This concentration of alcohol is effective in killing bacteria and viruses without damaging the material of the comb.
  • Soak the comb: Pour the prepared alcohol into a container and make sure the amount of alcohol is enough to completely soak the comb. Then place the comb in the alcohol, making sure that every part of the comb comes into contact with the alcohol. Generally, the soaking time should be at least 5 minutes to ensure that the alcohol has enough time to kill the pathogens.
  • Washing and drying: After soaking, remove the comb and rinse well with water to remove any residual alcohol. Afterward, gently wipe the comb with a clean towel or leave it in a well-ventilated area to dry naturally. Make sure the comb is completely dry before using it to prevent moisture from causing bacteria to grow again.


  • Ensure that it is operated in a ventilated environment to avoid inhaling alcohol vapor.
  • If the comb is made of plastic or other materials that are not resistant to heat, do not use high temperatures to sterilize it as this may damage the comb.
  • Sterilize regularly to keep the comb clean and hygienic.

2. Sterilizing using high-temperature

High-temperature disinfection is the use of high temperatures to kill bacteria, viruses, and other pathogens.

  • Boil with hot water: Place the comb in a clean pot and add enough water to ensure it covers the comb. Heat the water to boiling and keep it boiling for 5-10 minutes. This time is enough to kill most pathogens. After boiling, switch off the heat and allow the comb to cool naturally in the hot water for some time.
  • Use steam to sterilize: If available, you can use a professional steam sterilizer to sterilize. Place the combs in the basket of the steam sterilizer and set the time and temperature according to the instructions of the device. Usually, steam sterilization needs to last for 15-30 minutes.


  • Before sterilizing at high temperature, make sure the comb material can withstand the high temperature, otherwise, the comb may be damaged.
  • During the sterilization process, operate carefully to avoid burns.
  • After sterilization, rinse the comb with clean water to remove any limescale that may remain.
  • When drying the comb, place it on a clean towel or in a well-ventilated area.

Other disinfection methods

1. Using a UV steriliser

A UV sterilizer is a tool that uses the germicidal principle of ultraviolet light to disinfect.

  • Preparing the UV sterilizer: Place the UV sterilizer on a smooth surface and make sure the sterilizer is clean. Switch on the sterilizer and follow the instructions of the unit to warm it up, which usually takes a few minutes.
  • Place the comb for sterilization: Place the combs on the shelves inside the sterilizer, making sure that the combs do not block each other so that the UV light reaches every part evenly. Set the appropriate disinfection time according to the instructions of the sterilizer. Generally, the disinfection time is between 15 and 30 minutes, depending on the power of the sterilizer and the degree of cleanliness of the combs.
  • Completing Disinfection: After the disinfection time, switch off the UV sterilizer and remove the comb. As UV light is harmful to human skin and eyes, avoid direct exposure during operation. The sterilized comb can usually be used directly or left to dry naturally in a clean place.


  • When using the UV sterilizer, make sure that no one or pets are in the room to avoid UV light causing harm to people and pets.
  • Regularly check the UV lamp of the sterilizer, if the lamp is aging, it needs to be replaced in time to ensure the disinfection effect.
  • The UV sterilizer is suitable for a wide range of comb materials and is a gentler way of disinfecting.

2. Soaking in a disinfectant solution

Soaking in a disinfectant solution is a common method of disinfection, especially for items that do not tolerate high temperatures.

  • Choose the right disinfectant: There are a variety of disinfectants available in the market, such as chlorine disinfectant and hydrogen peroxide disinfectant. When choosing a disinfectant, make sure it is suitable for the material of the comb and follow the instructions in the product manual.
  • Prepare the disinfectant solution: Dilute the disinfectant solution to the appropriate proportion according to its concentration requirement. Usually, the disinfectant is labeled with the dilution ratio and instructions for use.
  • Soak the comb: Pour the diluted disinfectant into a container, making sure there is enough to cover the comb. Place the comb in the disinfectant, making sure that every part of the comb is in contact with the disinfectant. Soak for the recommended time according to the instructions on the disinfectant solution, usually between 10 and 30 minutes.
  • Washing and drying: At the end of the soaking time, remove the comb and rinse thoroughly using water to remove any residual disinfectant. Gently wipe the comb with a clean towel or place it in a well-ventilated area to dry naturally.


  • Wear gloves and a mask when using the disinfectant solution to prevent irritation of the skin and respiratory system caused by the disinfectant solution.
  • Ensure that you operate in a ventilated environment to avoid inhaling vapors from the disinfectant.
  • Do not mix different types of disinfectant to avoid the generation of harmful gases.

3. Using an ozone sterilizer

An ozone sterilizer is a device that uses ozone gas for disinfection with high efficiency and broad-spectrum germicidal ability.

  • Prepare the ozone sterilizer: Place the Ozone Steriliser in a smooth, dry place and ensure that the cabinet is clean and free from debris.
  • Place the combs: Place the combs to be sterilized on the shelves inside the sterilizer, making sure that there is enough space between the combs so that the ozone gas can circulate fully.
  • Set the disinfection time: Close the door of the sterilizer and set the appropriate disinfection time according to the sterilizer’s instructions. Generally, the disinfection time is between 20-60 minutes, depending on the power of the ozone generator and the degree of contamination of the combs.
  • Start disinfection: Press the start button, and the ozone generator will start to work and produce ozone gas for disinfection. During the disinfection process, avoid opening the door of the sterilizer to avoid ozone leakage.
  • Finish disinfection: After the disinfection time, wait for some time to let the ozone decompose naturally, usually 10-15 minutes. Open the door of the sterilizer and remove the comb. As ozone is strongly oxidizing, make sure that the ozone in the cabinet has finished decomposing to prevent irritation to the skin and respiratory tract.


  • When using the ozone sterilizer, ensure that there are no organic and flammable substances in the cabinet as the ozone may react with these substances.
  • Follow the product instructions when operating to ensure safe use.
  • The ozone sterilizer is suitable for combs made of all materials and is an efficient and safe way to sterilize combs.

Comb maintenance and cleaning

Maintenance and cleaning of combs is the key to keeping them hygienic and prolonging their service life.

The importance of regular cleaning of combs should not be overlooked and it is recommended that combs are cleaned at least once a week. This not only removes accumulated dirt and bacteria but also ensures comfort when combing and healthy hair.

2. Cleaning method

  • Before cleaning, use a tool such as a flat comb with fine teeth or a toothpick to pick out tangled hair and dirt between the teeth of the comb.
  • Soak the comb in a solution of warm water and a small amount of detergent for about 30 minutes to allow the detergent to soften the dirt.
  • Use a soft-bristled toothbrush or an old toothbrush to gently brush all sides of the comb, especially the bottom and roots.
  • Once clean, rinse thoroughly with water to ensure there is no residual detergent.
  • Gently wipe the comb with a clean towel or leave it to dry naturally in a cool, airy place. Avoid exposure to direct sunlight to avoid deformation or cracking of the comb.

3. Maintenance precautions

  • Avoid exposing the comb to high temperatures or humid environments to avoid deformation or mold.
  • When using the comb, hold the back part of the comb to avoid breaking the teeth of the comb by excessive force.
  • When not in use, store the comb in a dry place and avoid collision with other hard objects.
