Hydrogen peroxide

Hydrogen peroxide has been used for decades by women to lighten their hair. This method is quite ambiguous, and has both strong supporters and opponents. If used correctly, the product can give strands not only a light shade of hair, but also softness and shine, but if used incorrectly, it can cause stiffness and yellow hair.

What is this?

Peroxide is a liquid that dissolves well in alcohol and water. It has a characteristic metallic flavor and lack of color and smell.

It is widely applied in medical practice, the food and chemical industry and in a life. Also among women the method of clarification of hair by hydrogen peroxide in house conditions is extended.

Impact on hair

By coming into contact with oxygen, the hydrogen peroxide oxidizes. Melanin (the pigment contained in the hair that determines its colour) is discoloured by the oxidation process. This is the effect of peroxide on the strands.

Pros and cons of peroxide


  • Low cost and affordability (you can buy in any pharmacy).
  • Relative safety (not as burnt hair as some ammonia dyes).
  • Rarely causes allergies, has no unpleasant smell.
  • After clarification hair becomes more obedient, get shine and elasticity.
  • Hydrogen peroxide helps to get a beautiful shade, reminiscent of slightly sun-burned strands.


  • If the concentration of the solution is not correct, the curls can get an unnatural yellowish or reddish shade.
  • The procedure should not be used too often as the hair will become dry.
  • If you choose too long a time of lightening with initially fine and brittle hair, it is possible that your hair will fall out.
  • Unlike dyeing in the cabin, peroxide can be used to dye your hair irregularly.

The process of dyeing, despite its simplicity and availability, can affect the condition of the hair both positively and negatively.

Before and after the peroxide bleaching

Dark-haired girls won’t get a platinum shade, but they can lighten their hair by 2-3 tones. At the same time you need to be ready that the hair will get a slightly reddish shade.

If the hair shaft is light-blonde by nature, you can be lightened to blonde.

Red hair should be used especially carefully, as there are cases when after discoloration of the strands acquired an orange shade.

The easiest way to do this is by nature with blonde hair: depending on the seasoning time, the final result may vary from wheat to California blonde.

How to use peroxide

Exposure time and concentration of the solution:

  • For short haircuts you need about 30 grams of solution.
  • For medium-length hair clarification, about 50 grams of solution is required.
  • For long hair you need to take 50 grams or more of the solution.

Percent of hydrogen peroxide content in the solution:

  • If the hair is thick and hard, take a concentrated solution – 8-12%. Time of endurance of a solution on a hair shaft varies from 2 hours to one night. Because of the thickness of the hair, they may have to be clarified several times.
  • For medium hair thickness 6-8% solution is suitable. Strand contact time should be 1 to 2 hours.
  • If the hair is very thin, use a 3-5% solution. Keep hydrogen peroxide on your hair for half an hour to an hour.

Hair density should also be taken into account when choosing concentration and time of clarification. If the hair shaft is porous, the contact time should be kept to a minimum.

This also applies to the concentration of the composition: with porous hair that gets wet quickly during washing, the hydrogen peroxide solution should have a lower concentration than with strong, hard-to-wet hair.
