Does hydrogen peroxide drive lice and nits

Попробуем разобраться, следует ли выводить вшей перекисью водорода...

It is known that hydrogen peroxide affects lice and nits in approximately the same way as some other folk remedies, in particular kerosene and vinegar. Namely - the parasites themselves die or try to spread out of the place of its application, but using hydrogen peroxide from head lice, and even more so on the pubic area - from the point of view of specialists, the occupation is very risky.

При использовании перекиси водорода от вшей стоит думать не только об эффективности средства , но и о безопасности его применения

How peroxide is dangerous to lice, so it can be dangerous for the skin and hair of a person : if it is misused, serious skin burns can be obtained, as well as other unpleasant side effects. Therefore, even if you still decided to use hydrogen peroxide to remove lice , you should strictly follow the rules of its use and be ready for some troubles, which will be discussed below.


"It was like this, I was poisoned with lice peroxide. I was afraid to take kerosene, I decided to withdraw them with something more "medical". The result is neither lice, nor hair, nor, actually, hair. Rather, something is left on the head, but it's hard to call it hair. Plus, such a non-weak chemical burn in the area of ​​the temples. It's a good thing that in life with a short haircut and after a good bribe to a hairdresser she was able to create a sort of painted business hairstyle on my head. I do not play games like that anymore, and my daughter licked her with a good and expensive cream. "

How does hydrogen peroxide affect lice?

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

So, for example, hydrogen peroxide very effectively destroys bacteria, viruses and fungi, which provides reliable disinfection in the treatment of her wounds. When pouring peroxide deep and pinched ulcers and boils, it helps to separate from healthy tissues pus and necrotic areas, thus helping to avoid the development of gangrene and aggravation of the patient's condition.

Перекись водорода обычно применяется для дезинфекции ран, так как является мощным окислителем

Extremely active hydrogen peroxide also affects lice - it damages the outer integument of an insect and literally burns internal tissues when ingested in the respiratory tract (spiracles). Although remotely, but, nevertheless, a similar way to lice acts and acetic acid in more or less high concentrations.

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

Almost always after treatment of hair with peroxide, surviving lice remain, not dead, but severely injured and unable to feed, crawl and multiply. Therefore, before removing lice with hydrogen peroxide, it is necessary to prepare a thick comb in advance (it is better to use special combs from lice) with which such weakened individuals can be easily combed after hair treatment.

Rules for the application of peroxide

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

Перед применением перекись водорода нужно разбавить водой.

Даже разбавленная в два раза перекись водорода сохраняет свою высокую активность от вшей, становясь при этом менее опасной в обращении для человека.

Immediately should be prepared for the fact that even with a brief application of peroxide hair will change color and become lighter. And even an occasional delay can completely discolor them.

Do not confuse the usual 3% solution of hydrogen peroxide, 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!

To excite lice and nits with hydrogen peroxide should be in such a sequence (we are talking about a 1.5% solution, which is obtained by diluting the pharmacy by 3% twice):

  1. The skin is tested for sensitivity to the solution: several drops are spread on the skin behind the ear or on the elbow bend and left for a few minutes, after which they are washed off with water. If there are no red spots left on the site of application, you can proceed further. Redness or itching - obvious signals that the skin is easily burned with peroxide and when applied to the entire head, you can get an extensive chemical burn. If such redness from a single drop has appeared, peroxide can not be used. Перед использованием перекиси водорода обязательно нужно проверить кожу на излишнюю чувствительность к ней.
  2. The second stage - peroxide is applied to the head with a sponge, while the hair is divided into strands and wetted by the solution along the entire length. The solution should get wet and the skin under the hair. The entire procedure should be carried out quickly enough, since it is possible that in the places treated first, a sharp pain and irritation, requiring washing off of the solution, will begin, and a part of the hair will not be processed yet. During treatment, avoid contact with the solution in the eyes.
  3. After 7-10 minutes, the head is rinsed with water and soap, you can sprinkle it with citric acid and rinse again. Через некоторое время после обработки перекисью волос нужно вымыть голову с мылом.
  4. At the end of the procedure, wet hair should be carefully combed out with a special comb from lice.

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


"I decided to go to the salon, my hair will be discolored, color, and I will be without lice in a new color. But in the salon they saw what was in my head, they arranged a scandal. So ashamed, I felt like a bomzhiha. Etched lice at home by Nixom ... "

Irina, Taman

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

Если вшей много, то избавиться от них только лишь с помощью перекиси водорода бывает проблематично.

The degree of lightening of hair with the use of hydrogen peroxide depends on the concentration of the substance and the time of its aging on the head. For 7-8 minutes of exposure to a 1.5% solution, hair color practically does not burn out.


"Grandma told me that peroxide is good for lice. I know that it is used for bleaching hair. Why not do it all at once? I bought myself a paint, peroxide, called my friend, we sat down, my head was plastered with peroxide, we waited until we started to pluck it, and washed away a lot of lice in the bathroom. Probably, the part remained on the hair, but also dead. Painted, and all - no lice, brown hair is. "

Katya, Yekaterinburg

Safety above all: how not to get a chemical burn instead of lice?

It must be remembered 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.

Вши вызывают немало проблем, но неграмотное использование перекиси водорода может причинить еще большие неприятности.

If peroxide does not want to be replaced with safer means, in order to avoid side effects it is necessary to observe several rules when applied from lice and nits:

  • Be sure to check the sensitivity of the skin before each application of the remedy (even if you do not have an allergy to peroxide, suddenly you have not diluted it properly and it is too concentrated).
  • Do not keep peroxide on your head, if burning and tingling began to occur.
  • Do not repeat the procedure "to fix 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 absolutely unpredictably. Also, do not use peroxide if there are wounds, irritations, rashes of any nature on the head. After treatment with peroxide, the healing of such lesions can occur with the formation of scars and scars.

Нельзя применять перекись водорода для выведения вшей у детей.


"First time lice peroxide with peroxide. More of these nonsense, do not do it - it's good that I've been poisoning myself. Hair turned white, broke, behind the ears and on the back of the head burns appeared, although it seems that everything was done according to the instructions. I survived somehow, after a year I had to poison both myself and my daughter. I bought a pedulin shampoo, washed my head once - and no irritation, no parasites. "

Tatiana, Vologda

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

Preparations against lice, which give a quick and reliable result today in the market a huge variety:

  • shampoos from lice - Pedilin, Parasidosis, Lais-Gard Шампунь от вшей Педилин

To combat lice in children, as well as with a special weakness of hair, one should definitely prefer these means.

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