Does Hair Bleach Kill Lice? [2022 updated info]

Does hair bleach kill lice? Well! Head lice can infect anybody with hair. The greatest danger of lice infestation is for children attending nursery and kindergarten programs and their parents and guardians.

Head lice are tiny, wingless insects that dwell in hair and on people’s scalps. They are about the diameter of a sesame seed and come in a variety of hues, from translucent white to brown.
This content will talk about different ways to get rid of head lice. Let’s start with the basics:


About Head Lice

Lice feed on human blood and require it to live. The scalp is where they may survive for 30 days or longer. They lay three to five white nits/lice eggs each day.

There have been no studies on the impact of hair dye on head lice infestation. However, there is a lot of anecdotal evidence that might remove them. Hair dye, on the other hand, does not kill head lice or nits.

How Hair Dye Affects Lice?

Hair dye comes in a variety of forms. Permanent hair dye is used to destroy lice.
Hair dyes, for example, are permanent dyes that include ammonia. Ammonia is an alkaline chemical that generates a harsh gas when exposed to air. Hair dye may be productive to kill head lice.

Hydrogen peroxide, which has a more long-lasting effect, is also used to treat this issue.
A hard shell protects nits.

The chemicals in hair dye can’t break through the shell or detach the natural glue-like substance that holds the shells to hair. That’s why permanent hair dyes are not capable of removing nits before they hatch.

Does Hair Bleach Kill Lice?

Bleach damages hair by removing color. It also includes hydrogen and stearyl alcohol, which may assist with treating lice on the scalp. The strong chemicals in hair bleach kill head lice as they help eradicate lice from the scalp, but they are not very advantageous in terms of nits removal because they do not work well against nits.

How Hair Dye May Kill Lice?

If you want to try using hair color to remove lice fast, it is advised that you apply the hair dye every week until the nits and lice are completely gone.

Combining bleaching or dyeing your hair with additional lice removal treatment, such as using vinegar or combing.

Keep in mind that there is currently no scientific evidence that supports the use of vinegar to kill lice eggs or loosen the glue that connects nits to the hair. Anecdotal evidence may suggest that vinegar kills immature lice.

If you’d want to give hair dye a go as a lice treatment, follow these guidelines:

  • To remove most lice, start with vinegar. Wet your entire scalp using a 50 – 50 mixture of vinegar and warm water. The acidity in the solution should be at least 5%. Use the vinegar solution to work it down each hair shaft at the nape of the neck, behind the ears, and near the scalp. Leave the solution for 5 to 15 minutes. Wash it off if you feel a burning sensation.
  • Hot water should rinse the water solution and vinegar out of your hair
  • Remove as many nits and live lice from your hair using lice comb. Before reusing the lice comb, clean it in very hot water and soak it overnight
  • In a well-ventilated area, combine the hair dye following the instructions on the package.
  • Pour the dye on your scalp. Concentrate on the same regions as you did with the vinegar treatment: at the base of your skull, behind and around the ears, and the nape of your neck.
  • Rinse the hair color thoroughly.
  • Comb your hair once more with hair brushes or head lice comb.
  • To dry your hair, use a hot hairdryer. This can aid in killing lice that may be left behind.
  • If you can’t remove every nit within an inch or two of the scalp, you will likely have lice again in about seven days due to the head lice cycle.
  • If you have lice on your hair, it won’t deter them or keep you from getting infected if you reencounter them.

Safety Precautions

Permanent dyes can alter your natural hair color through chemical reactions. They can also induce allergic responses and irritate your scalp. The face, neck, and scalp may experience the following side effects:

  • Welts or hives
  • Swelling
  • Burning Redness
  • Nasty Chemical Burns
  • Itching

If you color your hair or bleach it more than once a month, you might damage it and cause it to thicken or dry hair

When applying these products to your hair, remember to use the disposable gloves that usually come with them to safeguard your hands and other body regions you may touch.

Make sure no product gets into your mouth, nose, or eyes. It is also crucial to avoid breathing in the fumes produced by hair dyes. Always dye your hair in a well-ventilated area to ensure that you do not inhale any strong chemicals.

Hair bleaches and dyes are not advised for use as a lice-removal solution in children. A child’s head is usually more delicate in texture than adult hair, making it more vulnerable to chemical damage from bleaches and dyes.

Children’s hair may be more susceptible to chemical reactions that affect the airways, eyes, hair, and scalp.

Other Lice Treatments

There are a plethora of at-home lice treatments, and each one has its own set of pros and cons. You may need to test numerous before finding the suitable ones for you.

Some adult lice are becoming resistant to common therapies such as stearyl alcohol and medicated lice shampoo, typical for insects. The manual removal of nits and lice using a fine-toothed lice comb is required for all home head lice treatments.

You can include any head lice treatment:

  • Nix and other over-the-counter super lice treatment products contain a variety of insecticides, some of which may not be safe for nursing and pregnant women, small children, toddlers, or infants. If you have any doubts, talk to your doctor
  • Head lice may be suffocated by applying mayonnaise, olive oil, or tea tree oil to the scalp. This unscientific remedy, which has not been proved successful, demands that you allow mayonnaise or olive oil to sit on the hair for 24 to 48 hours under a shower cap. It is possible that braiding long hair or pinning it up after treating the scalp will assist.
  • Coconut oil has not been scientifically proved to work, but it is non-toxic and natural. Try applying coconut oil after treating your hair with a vinegar solution to improve the efficacy.
  • You can repel lice by using essential oils such as rosemary, lavender, peppermint, or tea tree oil. You can go for essential oils diluted in any carrier oil as a smothering treatment.
  • If home treatments such as harsh combing and Nix do not work, talk to a doctor about prescription medicines that may assist.
