Do you have to use chemicals for perming your hair?

You don't have to use chemical solutions to perm your hair. Earlier, perming hair was done by placing a tong-like tool on a fire to heat it, and then wrapping the hair around the tongs to curl the hair. It's called blanching.

You can directly perm your hair. Common self-perm techniques:

First of all, it is necessary to wet the hair with warm water, it is best to use a spray head, it is more even, it is not recommended to use cold water, it is easy to catch a cold. Wipe off the excess water with a towel and don't wipe it too dry.

Then, do a bow and throw your hair in front of you, preferably not standing up straight and applying gel cream to your hair. At this time, the posture is the same as wiping the water with the hair upside down, pouring the gel cream on the hands first (not too much, otherwise it is easy to make too many places just wiped, and the second time the place is too little, uneven, to be wiped in 3 or 4 times), rub the palms of both hands with each other so that both hands have gel cream.

Then, wipe evenly from roots to ends.

It is estimated that all the places that should be wiped have been wiped, then you can stand up straight! Use your fingers to straighten your hair a little, remember to use your hands, never a comb!

Finally, hold the ends of the hair with your hollow hand and scratch it a few times at the roots! That is, to catch the curls of hair out of it! It's important to go through all your hair!

Okay, almost, shake your hair, let your hair be natural, and you're good to go!

Chemical composition of perm hair potion: hydrothioacetic acid, ammonia (ammonia), fragrance, distilled water.

The main ingredient of the perm.

1. Hydrothioacetic acid, which contains hydrogen atoms, separates the sulfur key locks during the perm process.

2. Amonia (ammonia), open the hair and make the skin into it, so that the hair swells and is easy to absorb the potion, other ingredients: hair care ingredients, fragrances, distilled water.

The ammonium mattelic acid (alkaline) in the special perm potion enters the cortical layer through the hair cuticle of the hair layer of the hair layer, changing the protein chain structure of the hair to form curls. Hair is a keratin protein that is made up of a series of amino acids. These macromolecules are like long chains, and amino acids are the links in them.

An amino acid called cysteine, which is abundant in hair.

Two cysteines placed in different places, the sulfur bridge bonds are connected to form a cystine. These cystines resemble small springs that give the hair a certain shape and elasticity. The perm first uses a reducing chemical solution to disassemble the small spring of cystine, so that the cystine is thinned.

The sulfur bridge bond breaks off and becomes two cysteines.

At this time, the amino acid links of the hair loosen and coil into a certain waveform at the mercy of others. Then apply the fixative so that the cysteine that disconnects the small spring is combined in pairs nearby to form a new spring and fix the hairstyle.

The principle of chemical perm: when perming, the hair is physically wound on the core of different diameters and different shapes, and the first dose of perm (reducing agent) enters the hair, and about 45% of the second-flow bonds are cut and disturbed, so that they become monosulfide bonds, which are squeezed, deformed and moved by the influence of factors such as the shape, diameter and tensile force of the core.

Under the action of the second dose (oxidizing agent), these monosulfide bonds form a new set of difluidized bonds with another monosulfide bond in a new position, causing the hair to become permanently curled.

Chemical perm liquid, also known as cold perm liquid, is a perm method that uses thioethyl thiocolethol as a cold perm to curl hair into a hairstyle. Cold perm is convenient and simple.

Main ingredients: At present, most of the chemical perm reagents used in various chemical perm shops are "cold perm liquids" produced from different origins, with a wide variety and different formulas, but the main components of Chenhe are ammonia bicarbonate, barium hydroxide, sulfur veins, ammonia, etc., which is an alkaline liquid with a pH value of 9-10 [1].

Summary. Hello, it is a pleasure to serve you, the chemical composition of the perm hair potion: hydrothioacetic acid, ammonia (ammonia), fragrance, distilled water.

The chemical composition of the perm potion.

Hello, very high waiter or Xing can serve you, the chemical composition of the perm hair potion: hydrothioglycolic acid, ammonia (ammonia), fragrance, distilled bitan. The main ingredient of the perm 1, hydrothioacetic acid, contains hydrogen atoms, which separate the sulfur bonds during the perm process.

2. Amonia (ammonia), open the hair to make the skin formed, so that the hair swells and is easy to absorb the potion, other ingredients: hair care ingredients, penitent fragrances, distilled water.

Allergic to**?

Hello, people with allergies will definitely be allergic, and generally people will have slight scalp discomfort, such as a little itching, or like pinpricks.

Perm potions usually consist of a perm and a neutralizer. Hair perms are mainly composed of a mixture of ammonia and thioglyconic acid, but there are also other types such as lanolin, proteins, moisturizers and conditioners. Thioglycoic acid is the active ingredient and is the main component that alters the structure of the hair.

Ammonia is alkaline and causes hair to swell. The concentration of perm potion can be changed by increasing or decreasing its thioricaronic acid and ammonia content. Neutralizers contain components of hydrogen peroxide and sodium bromide, and are generally used in conjunction with ingredients containing hair conditioners.

In the process of perming, the alkali in the perm potion will cause the loss of natural oil in the hair, and the perm potion is added with lanolin, protein, emollient and other substances as a hair care ingredient, which can replace the lost natural oil, so that the hair will not be too dry and brittle, and minimize the damage of the perm potion to the hair. Some contain protein, lanolin, used to repair **holes, **damaged hair, a special hair conditioner applied to the hair before perming, called pre-perm conditioner, can be used for hair care treatment before perming. In order to meet the needs of various types of hair perms and according to their hair conditions, various concentrations of perm potions can be selected, and the concentration of perm potions can be determined according to the content of its pH value and the number of active ingredients.

There are generally three types of perm potions; Alkaline perm potion (pH is greater than neutral perm potion (pH is acidic perm potion (pH is.
