Does Hair Dye Kill Lice? Treatment & Natural Remedies For Lice
Does Hair Dye Kill Lice?
Head lice are a terrible fear in everyone’s mind. It is an annoying and embarrassing condition that affects the life of most people. Kids, youngsters, and caretakers have the utmost possibility of having head lice invasion. Head lice are wingless tiny crawling parasites (insects) that live on people’s hair and feed on the scalp’s blood. The insect’s size is that of a benniseed (sesame), and the color varies from white to brown. There are inadequate studies to validate if hair dye eradicates lice. However, several unscientific facts indicate that chemicals in the hair dye, viz, hydrogen peroxide and ammonia, might kill them. Yet, one should never forget that no hair dye can kill the lice eggs (nits).
The article will explore how chemicals in hair dye impact lice, the use of hair dye to eradicate lice, hair dye’s precautions and risks, lice treatment, and some natural ways to tackle lice effectively.
Does Ammonia in Hair Dye Affect Lice?
- Most permanent hair dyes have hydrogen peroxide and ammonium persulfate (chemical). Hydrogen peroxide is a chemical substance with a pungent odor that can kill germs. Ammonia is a poisonous erosive substance that liberates an annoying gas that the lice cannot bear, making them die.
- Informal facts suggest that alkaline ammonia and hydrogen peroxide in permanent dye help to kill the lice.
- Research studies have found that hydrogen peroxide efficiently kills sea lice, but further studies are needed to validate its consequences on head lice.
- The lice eggs have tuft shells with a gluey substance that helps them stick to the hair. The chemicals in hair dye cannot break the egg shells or the gluey material and hence cannot kill the nits. The lice come out from the nits in around ten days. So, the individual must do the hair dye again after ten days to kill the lice .
Does Bleaching Hair Kill Lice?
- Most hair bleach contains ammonium persulfate, stearyl alcohol, and hydrogen. Ammonium persulfate is a colorless substance with an unpleasant odor that helps remove the original color. Stearyl alcohol is a fatty alcohol in most cosmetics and dyes and is slightly toxic to insects.
- These chemical substances in hair bleach might help kill the lice. But notably, these substances are again ineffective to lice eggs, similar to hair dyes .

Treatment to Kill Lice Instantly
There are many lice treatments to try at home, but most of them, viz; medicated shampoos have become ineffective for most lice due to the development of resistance against them. However, all anti-lice treatment requires post-combing with a fine comb.
Some of the standard treatments are listed below-
Over-the-counter anti-lice treatment
Nix (1% permethrin lotion)
- It is a non-natural treatment to kill both lice and eggs. After treatment, it leaves a residual amount in the hair that kills the nymphs (young lice) that did not die in the first treatment.

- Repeat the procedures daily for about a week or until all the lice have moved out.
Wash the items
- Clean all the lice-infested things in hot water, preferably 54 degrees centigrade.
- Then, insert them in a hot dryer for twenty minutes to kill any lice and their eggs.
- One can also use vacuum cleaners to clean the floors where lice have fallen , .
Dyeing Hair After Lice Treatment
Lice treatments usually wholly remove the lice and eggs. Lice treatment can impact the hair, depending on the type of treatment, hair, and other factors. After lice treatment, an individual might experience hair dryness and temporary color change due to certain chemicals viz; permethrin present in the treatment.
There are specific risks in dyeing hair just after lice treatment, and are as follows-
- Some lice treatments can cause sensitivity in some individuals. So, using hair dye just after treatment will only augment the allergic reaction.
- Lice treatment contains chemicals that weaken the hair, so immediate hair dyeing after lice treatment might cause hair loss and breakage.
- Dyeing hair too early after lice treatment might interfere with the lice treatment chemical, making it ineffective in nits (lice eggs) removal .
Time to wait before dyeing after lice treatment
The waiting time depends on the lice treatment one is taking up. Here are some of the waiting times for different lice treatments-
Natural lice treatment
- Wait 14 to 21 days before hair dyeing for vinegar or tea tree oil treatment. It will give time for the hair to recover from the treatment.
Chemical lice treatment
- For anti-lice shampoos containing pyrethrin or permethrin, wait 7 to 14 days before hair dyeing.
- It will allow the hair to recover from the probable chemicals from the lice treatment.
Prescription lice treatment
- Ask your doctor how long to wait before hair dyeing for prescription lice treatment.
- After lice treatment, one should choose gentle hair dye products free from peroxide or ammonia to minimize hair damage.
Life Span & Life Cycle of Lice
How long do lice live?
Lice feed on blood and survive for around thirty days. Female lice lay several nits, i.e., eggs (usually 4 to 6) daily.
Life cycle of lice
- The life cycle starts with the egg or nits. The egg is white and attaches to the human hair with the glueyness in the egg’s shell.
- After about eight to ten days, the egg hatches to become a nymph (young louse). The nymph finally grows into adult lice in around ten to twelve days. The adult lice live for about 21 to 28 days.
- Lice are parasites, and they always need a host, viz; human, to live and reproduce.
- The lice die without a host in around one day. Although lice can move on objects, they can’t survive more than 24 hours in them without a human host , .
Hair Dye to Kill Lice-An Assessment
- Hair dye might destroy lice due to its lice-sensitive chemical contents, such as hydrogen peroxide and ammonia.
- Hair dye cannot eradicate the eggs due to the hard shell around them. So, lice will likely return once they hatch, even after hair dye.
- The information that hair dye and bleach kill lice is theoretical and informal. There is no scientific proof. Further research studies are warranted to validate the effect of hair dye on lice.
- Individuals dying their hair must take necessary precautions to prevent complications from the dye chemicals.
- Other effective treatments are also available to eliminate lice and nits.
- Individuals willing to remove lice with dye or bleach must use a lice comb to withdraw from the hair and keep an eye on the lice that would come up after a few days.
