Does hydrogen peroxide allow lice and nits to get out

≡ Article 16 comments

Let's try to figure out whether to remove lice with hydrogen peroxide ...

It is known that hydrogen peroxide acts on lice and nits in about the same way as some other folk remedies, in particular kerosene and vinegar. Namely, the parasites themselves, when they are processed, die or try to spread out from the place of its application, but using peroxide from lice on the head, and even more so on pubic, from the point of view of specialists, is a very risky job.

When using hydrogen peroxide against lice, it is worth thinking not only about the effectiveness of the product, but also about the safety of its use.

As far as peroxide is dangerous for lice, it can also be dangerous for human skin and hair.: if it is used improperly, serious skin burns can be received, as well as other unpleasant side effects. Therefore, even if you do decide to use hydrogen peroxide for removing lice, you should strictly follow the rules of its use and be prepared for some troubles, which will be discussed below.


“I had it, poisoned with lice peroxide. I was afraid to take kerosene, decided to remove them with something more “medical”. The result - no lice, no hair, or, in fact, hair. Rather, something remained on the head, but it is difficult to call it hair. Plus, such a weak chemical burn in the temples. It’s good that I have a short haircut and after a good bribe to the hairdresser, she was able to create on my head a kind of dyed business hairstyle. I don’t play such games anymore, and my daughter lice hunted with good and expensive cream. ”

How does hydrogen peroxide act on lice?

Hydrogen peroxide is used for various medical purposes primarily as a chemically active substance, which, due to its strong oxidizing properties, leads to the decomposition of complex organic molecules and biological structures.

The structural formula of hydrogen peroxide

For example, hydrogen peroxide is very effective at killing bacteria, viruses, and fungi, which ensures reliable disinfection during the treatment of wounds. When peroxide is poured into deep and festering ulcers and boils, it promotes the separation of pus and necrotic areas from healthy tissues, thereby helping to avoid the development of gangrene and aggravation of the patient's condition.

Hydrogen peroxide is usually used to disinfect wounds, as it is a powerful oxidizing agent.

Hydrogen peroxide is also very active in lice - it damages the integument of the insect and literally burns out the internal tissue when it enters the respiratory tract (spiracle). Although distantly, nevertheless, acetic acid acts in a more or less high concentration in a similar way on lice.

Hydrogen peroxide is also effective against nits: the protective shell of the egg itself is intact, but the peroxide destroys the secret with which the nit is attached to the hair. After this treatment, the nits are much easier to comb out from the hair with a comb and even partially crumble themselves.

After treating the hair with hydrogen peroxide, the attachment of the nits to the hair weakens

Combing loose nits from the hair will help a special comb

Almost always after treatment with peroxide hairs, lice surviving on them remain, not dead, but severely injured and not capable of further feeding, crawling and reproduction. Therefore, before removing lice with hydrogen peroxide, a thick comb should be prepared in advance (it is better to use special lice combs), which can easily comb such weakened individuals after treatment.


Peroxide application rules

If you decide to use peroxide against lice, it should be used in a less concentrated form than it is sold in pharmacies.To do this, before you get rid of lice with hydrogen peroxide, the tool itself should be diluted with water at least twice (from 3% to 1.5%). If you do not do this, you run the risk of skin burns.

Before use, hydrogen peroxide must be diluted with water.

Even diluted twice the hydrogen peroxide retains its high activity against lice, while becoming less dangerous in circulation to humans.

Immediately, you should be prepared for the fact that even with short-term use of peroxide, the hair will change color and become lighter. And even an occasional delay can completely discolor them.

In no case should not be confused with the usual 3% hydrogen peroxide solution, which is sold in pharmacies and 30% solution, which can also be found in pharmacies (usually sold in cans), but which is incomparably more dangerous to handle. 30% peroxide is extremely aggressive and dangerous to health!

Lice and nits should be removed with hydrogen peroxide in the following order (we are talking about a 1.5% solution, which is obtained by diluting the pharmacy 3% twice):

  1. The skin is checked for sensitivity to the solution: a few drops are spread on the skin behind the ear or on the elbow bend and left for a few minutes, then washed off with water. If at the site of application there are no red spots left, you can proceed. Redness or itching - clear signals that the skin is easily burned with peroxide and when applied to the whole head you can get an extensive chemical burn.If such reddening from one drop appeared, the peroxide cannot be used.Before using hydrogen peroxide, be sure to check your skin for excessive sensitivity to it.
  2. The second stage - the peroxide is applied to the head with a sponge, while the hair is divided into strands and moistened with a solution along the entire length. The solution should be wet and the skin under the hair. The whole procedure should be carried out fairly quickly, because it is possible that in places treated first, there will be a sharp pain and irritation, requiring rinsing of the solution, and some of the hair will not be processed yet. When processing, avoid contact with eyes.
  3. After 7-10 minutes, the head is rinsed with soap and water, you can sprinkle it with citric acid and rinse again.After some time after treatment with peroxide, you need to wash your hair with soap and water.
  4. At the end of the procedure, wet hair should be carefully combed with a special comb for lice.

Lice and nits are combed from hair strand by strand.

Considering the fact that when bleaching and repainting hair, peroxide is usually applied for 20-25 minutes, this procedure also turns out to be detrimental to lice. Therefore, many women prefer to combine business with pleasure, and use hair dye to remove parasites.


“I decided so - I will go to the salon, my hair will discolor, they will be dyed, and I will be without lice in a new color.But in the cabin they saw that in my head, they made a scandal. So it was a shame, I felt bomzhihy. Louse grass house Nyx ... "

Irina, Taman

However, it should be noted that with a serious infection, even hair dyeing with their prior discoloration with peroxide is not always a guarantee for the destruction of all lice. Therefore, it is better to divide these procedures - first remove the lice, and then repaint the hair.

If there are many lice, it can be difficult to get rid of them only with the help of hydrogen peroxide.

The degree of hair lightening when applying hydrogen peroxide depends on the concentration of the substance and the time it is held on the head. For 7-8 minutes of exposure to a 1.5% solution, the color of the hair practically does not fade.


“Grandma told me that peroxide is good for lice.” I know that it is also used for bleaching hair. Why not do it all at once? I bought myself a paint, a peroxide, called a friend, we sat down, smeared it with peroxide, waited until the pinnacle began, washed off - and a lot of lice went to the bathroom. Probably, some remained in the hair, but also dead. Painted, and all - no lice, brown hair there. "

Katya, Ekaterinburg


Safety is paramount: how not to get a chemical burn instead of lice?

Be sure to remember that hydrogen peroxide is a very aggressive substance. In some cases, the consequences of its use are more serious than the problems caused by lice.

Lice cause a lot of problems, but illiterate use of hydrogen peroxide can cause even more trouble.

If peroxide doesn’t want to be replaced with safer products, in order to avoid side effects, it is necessary to observe several rules when applying lice and nits:

  • Be sure to check the sensitivity of the skin before each use of the product (even if you are not allergic to peroxide, all of a sudden you have diluted it incorrectly and it is too concentrated).
  • Do not keep peroxide on the head, if you started to feel burning and tingling.
  • Do not repeat the procedure "to consolidate the effect" or prevention - this is a serious stress of the skin and hair.

Do not use peroxide from lice for children and adolescents. Their skin can react to this drug completely unpredictable. Peroxide should also not be used if there are wounds, irritations, rashes of any nature on the head. After peroxide treatment, the healing of such damage can occur with the formation of scars and scars.

Do not use hydrogen peroxide to remove lice in children.


“The first time poisoning lice peroxide. I didn’t do more of such nonsense - it’s good that I hounded myself.Her hair turned white, broke, there were burns behind the ears and on the back of her head, although she seemed to be doing everything according to the instructions. She survived once, in a year she had to poison herself and her daughter. I bought Pedilin shampoo, washed my head once - and no irritation, no parasites. ”

Tatyana, Vologda


Alternatives to hydrogen peroxide: when is it better to prefer special drugs

Lice drugs that give fast and reliable results on the market today are a lot:

  • lice shampoos - Pedilin, Parazidoz, Lyse-GuardPedilin Lice Shampoo
  • emulsions and concentrates for their preparation - Medilis, Medifox, AvicinConcentrate for the preparation of emulsion from lice Medifox
  • sprays - Pedikulen, Nuda, ParanitSpray for the destruction of lice and nits Pedikulen Ultra
  • creams - Knicks, Nittifor.Cream Knicks for lice

To combat lice in children, as well as with a particular weakness of the hair, it is definitely necessary to prefer these drugs.

Each of the above drugs has its own contraindications, but they are all safer and easier to use than hydrogen peroxide. Their only drawback in front of this folk remedy is the cost, but for the sake of health and safety (especially when it comes to children) it is not worth saving in cases of infection with lice.

    Half a year we are already poisoning the child with expensive, safe, and most importantly “effective” pharmaceuticals: lice have been and are. The state has already spent on these funds. 4 days - and again run, although, like, combed everything. And large adult individuals run. Apparently, these shampoos and sprays do not even kill the lice, and even more so they don’t peel the nits - it was difficult to tear off some by hand. Burn 3% peroxide? It is ridiculous, how then are the scratches treated without washing it away, and no burns on the skin surrounding the scratch? Delirium (or the work of PR managers, manufacturers of shampoos).
